Corrosion Protection

Posted: Fri Feb 17, 2012 5:40 pm
by randy (psi)
Hello: Everyone, I am also a new builder, in fact the tail section kit for
the Rebel should be arriving mid February. I plan on putting the Rebel on
Floats and I am trying to make a decision on corrosion protection for the
aircraft. In particular should I prime all of the interior components and
if so with what product. I know Murphy suggests using Zinc chromate on
joints and dipping rivets, but is that enough for the water ( I also hate
Zinc Chromate for spraying) . I am interested in anyone's opinion.

Thanks
Randy

Subject: Wing Attach Fittings Paranoia

The Elite is coming along nicely. I'm working on the right
wing after knocking down a wall in my crowded workshop.
But am having an attack of bolt hole edge distance
paranoia.

Things have gone well and I am now fitting the front and
rear spar fittings. These are the fittings that attach the
wing to the fuselage (W-119 and W-124 which I believe are
the same part numbers on the Rebel).

The front and rear spars are pre-punched for placing
the spar fittings. The pre-punched holes at the spar root
have the normal 5/16" edge distance found on most parts.
However, these holes get drilled and reamed for either
AN3 or AN4 bolts which would require at least 3/8" edge
distance (for AN3 bolts).

As these fittings seem *really* small (for attaching something
as important as the wing). And the number of bolts doing
the attaching also seems small, I'm making every attempt
to keep tolerances tight.

The factory parts all seem to be manufactured correctly. I know
there are extra doublers in this area. But why is edge distance
not a problem here, when it seems like you'd *really* like that
extra metal?

Also, the construction in this area does not seem to allow
inspection or replacement of the bolts holding the front spar
fitting. As I'll be on floats, I'd like to be able to inspect
and replace all bolts as they can corrode over time from
water and abuse (especially salt water). Am I misreading
the manual or are these bolts all torque 'em and forget 'em?

I checked Wray's online manual and the Elite looks almost
identical to the Rebel in this area so words of wisdom and
comfort will help me sleep better.

Thanks,

Eric Fogelin

Eric, Torque 'em and Forget 'em, just like a Cessna or any other! Coat them
with epoxy chromate before installing so the water can't get in there! I
have fixed some pretty good wrecks (if you can call a wreck good). The wing
fittings have always been in perfect condition (after the fall) and I had
one where the cabin was narrowed at the rear attach fitting by 8", after
the
wing tip dug into the ground. The wing fittings were just fine, although
the
compression of all three torque tubes jamming together cause the opposite
wing to be damaged inside also. The Rebel that went in the lake and
cartwheeled bent the right wing up like a boomerang, but all fittings were
left like new! In most aspects of flight there is a compression load on the
attach fittings and not tension. Hope this lets you sleep at night now,
Wayne

Thanks, Wayne. I'm feeling better already.

But just to follow-up. How about the edge distance problem?
On the Rebel, is the Root Rib Attach Bracket (W-161) flush
with the root end of the front spar? If yes, then the Rebel
doesn't have an edge distance problem as the W-119 Front
Spar Fitting Attachment will be bolted 15/32" back from the
root end of the front spar. My W-161 bracket overhangs
the root end due to the 5/16" pre-punched holes in the front
spar used to align W-161.

I've got email into Murphy on what, if any, differences there
are in this area between the Elite and Rebel. They seem
almost identical, but something seems wrong.

Your insight and experience has been a great aspect of
this internet group.

Eric,
I have a "spare" Rebel wing out in the hanger and will have a look at it
later tonight (it's -39c so not to keen tonight) or in the morning, to
check
the edge distance. I am working on a SR wing set right now in the shop and
it has very minimal E.D. for the two bolts that hold the Root rib to the
front spar. I know Murphy load tests their wings before offering to the
market (unlike some others) so I wouldn't worry too much about it. The only
thing to check is that when you put the ribs in place, is the distance
between each rib set equal (for and aft) all the way along, to prove the
predrilled holes are in the right location and that you didn't get a bad
front spar.

Blue skies,

Wayne's right !! The Elite ailerons & flaps are COMPLETELY different
animals - there are extra hinge supports, weights in the front, and
large aerodynamic balance horns at the outboard ends.

Again - they added a lot of weight, complexity for building, and
lost roll effectiveness. Why ?? Because a bunch of potential customers
thought aluminum would look more like a "real airplane" - the old
"Cessna did it, so it must be good" thing !!! ;-(
(same reason the Elite was originally a tricycle ...)

FWIW on my Rebel the w161 overlaps the leading edge spar (inboard) on both
wings.
On the right wing I just barely have 1/2" edge distance on the leading edge
spar
for the AN4 bolts. The left wing has quite a bit less. In addition to
Wayne's
comments, I think maybe the spar doublers (.040 and .050?) reduce the need
for
the normal edge distance.

As far as corrosion goes, I chromated over the entire bolt. I asked MAM
about an
inspection/access plate and they said no, which I guess is not surprising
in
this area. I believe I had to insert the bolts with the head forward to
clear
the wing skin so there would be no way to remove them anyway.

There is a similar situation at the rear spar where the width of the flange
on
the root rib is not sufficient for the normal edge distance. I am sure that
MAM
has designed for this as well however.

cheers
Ken

Subject: Rebel 0145R

Hi gang,
I thought it was time to come out of hiding and make myself known. My
name is Frank Arndt and I live in Sarnia, Ont. (about 3hrs west of Toronto,
right on the US border). I bought 145R in Orangeville, Ont 90% complete
less
engine and hanging way up from the rafters. The workmanship was quite good
in my opinion.
I would like to say that this mail list has been a great resource of
idea's and opinions with your primary aim focused on saftey, which it
should
be. I am starting to feel real guilty for absorbing all your ideas but
offering the list nothing, so here goes:
I am not a "HorsePower nut" so my engine choice would probably not suit
most people on the list. I have decided to give the Subaru EA-81 a fair try
at Rebel 145R. I am currently flying a Karatoo (with another EA-81) which
is
overweight 970lbs+ and extreamely nose heavy as the airframe was not
intended for this engine. All that said, it flies not too bad and I figure
I
have to get better performance in 145R. I am almost finished my little
project with some instruments and paint left to do. 145R is relatively
light
(under 800lbs when complete, I hope!) and has all the safety modifications
done. All my flying will be on wheels, most of it solo and I'm not planning
any round the world trips, just a little air-time is what I am after. I am
hoping my new engine produces 85 to 90 HP, (I don't quite buy the 105HP
advertized) and I would be quite happy bumping along at 80 mph.
I don't want to bore you so I will shutup now.
I would love to hear your thoughts, (good or bad) and if there is anyone
out
there trying to do something similar I have lots of digital JPG's of 145R,
mostly the engine installation. Also I will share all my performance data
(good or bad) so anyone interested will learn from my experience.

Special thanks to Bob Patterson and Dave Bangle for your opinions up front
and honest.

Frank

Clay,
I am also working on instrument panel stuff. Aircraft spruce offers a
line of
2 1/4 " gauges that are supposedly vibration resistant. They are their
Microflite-1000 series. I have bought some of them and will try them out.
Mechanical oil press, mechanical oil temp, and voltmeter are the ones that
I
purchased. Their ammeter is only a 30 amp so I got a Westach with a 60 amp
+
shunt. The Microflight-1000's are fairly inexpensive and had a good
description
of them in the catalog. They look nice too. Check their web site it may
have the
same info. I have a vibration isolated main panel for the standard six pack
of
instruments and have not bought any of those yet. I also think that I will
isolate the small panel. The small 8-32 stud mounted shock isolators work
for me.
Same as Cessna panel mounts.
Good luck,
Rick D.

Subject: Re: Instruments

Clay,
One more point of philosophy. I elected to use 2 1/4" gauges instead of
specials such as some of the "many function" instruments. This will allow
me to
use just about anyones gauges if any of these conk out. I have used this
philosophy throught the aircraft. All of the fancy show all gauges put you
at the
mercy of that manufacturer. Which is exactly why I went the homebuilt
route. On
my C-172 I had to buy a small bracket that kept the front of the cowl from
bumping the engine. At $ 92.00 I almost croaked but I had no choice but to

Well said Rick,
Howard just loves his electronic (all in one, with the flashing red idiot
light) engine monitor. I won't name the brand. He did however have his
plane
tied to the dock for 2 days this summer, while he tried to get a hold of
the
manufacturer as all readouts were away off so he couldn't fly. On the 3rd
day he had me come up to the lake and with the owner of the Electronic
Company on the other end of the phone line, I reprogrammed his "hidden" set
up pages that had been zapped by a power surge due, to starting up with the
monitor turned on! Good thing he was tied to his own dock! But if you were
in the boonies, I guess if you know your plane well enough and that it
normally doesn't redline on takeoff, etc and temperatures/pressures usually
run normal you could chance flying to civilization. (NOT With me along for
the ride you won't) Or you do carry all the info and programming sheets
that
come with everything you are putting in the plane don't you! This will
allow
you to use you Cell Phone and call the manufacturer from Lake Timbucktwo.
What, no signal you say!!!! You did bring paddles, didn't you????

I guess I'm just an Analog type of guy also! (I did say Analog)

Clay,
One more point of philosophy. I elected to use 2 1/4" gauges instead
of
specials such as some of the "many function" instruments. This will allow
me to
use just about anyones gauges if any of these conk out. I have used this
philosophy throught the aircraft. All of the fancy show all gauges put you
at the
mercy of that manufacturer. Which is exactly why I went the homebuilt
route. On
my C-172 I had to buy a small bracket that kept the front of the cowl from
bumping the engine. At $ 92.00 I almost croaked but I had no choice but to
buy it
from Cessna. I am unsure installing about electronic ignition for just
this
reason. If I break down somewhere, who will help with repairs of your
custom
electronic stuff, but with the old magnetoes just about anyone can help.

Nothing leaps to mind - most are ok. Are you planning on having any
gyro instruments ?? Vacuum or electric ?? There ARE differences between
vacuum gyros meant for vacuum pumps, and those for venturi tubes - get
the wrong one, and it won't work properly !! Personally, I dislike
vacuum pumps - they suck about 3 hp. all the time, and need overhaul
too often for my liking. Venturi tubes won't hurt much - it's not
a 300 mph. airplane ! :-) If you don't plan IFR anyway, then maybe
just a standby electric turn-and-bank, just in case ! ;-)

Vertical card compasses are nice, but expensive - probably not worth
the price ... If you can find a good one at Canadian Tire - go for it !
At a recent Rebel Builders meeting, we heard about a new type of compass
that's available through Radio Shack for about $60 - electronic, and
easy to set up, even with extreme magnetic conditions (like steel tube
next to compass).

Get an airspeed indicator that covers your range as close as possible
- markings down to 20 mph, and up to 140 or 160, although even 130 would
likely do. Avoid the 250 mph types - too hard to read the 1" needle range
:-)
Many Rebel Builders are using the VAL panel mount radio - they cost
less than a hand held, and give good performance (8 watts), and have a
bright display that adjusts for lighting conditions. They have a 2 channel
flip flop switch which is handy for going to ground control quickly.
For about $75 extra, they will supply a made-up wiring harness, ready
to go - a bargain !

Hand-held GPS, with a bracket on the panel, is the most cost-effective
way to go. The technology is advancing quickly, so wait as long as you
can to buy - prices are falling. The fancy combination radio & GPS units
look sexy, but they're EXPENSIVE - both to buy, and maintain. If one
part goes, you lose both for servicing :-(

A moving map display is really nice, but we fly one Rebel with a
$140 GPS from the sporting goods store - works way better than our old
LORAN !! You can always move up, when you know what you want ...

You might want to check out photos of other panels - the standard
layout is becoming - electrical stuff on left angle panel, mounted on
a flip down panel with piano hinges top & bottom, with a doubler around
the hole. The flight instruments are often mounted on a floating panel
in front of the pilot - use 1/8" Lexan for this, and you can put labels
on the back, and paint the back. This looks great, and is protected.
The floating panel is mounted on shock mounts (or just bolts with
fuel line over them). Cut holes in the metal panel to match the floating
panel, but oversize about 1/4" or so - to keep the strength of the
panel (it IS structural). Attach a 1 1/2" aluminum angle to the bottom
of the panel - all the way across, and even out the angles. This angle
will stiffen up the panel AND give you a plave to mount the throttle,
mixture, carb heat, primer, and trim button, leaving space for 2 rows
of full sized instruments on the panel. (can be a 2" angle)

Glad you spoke up !! I'm sure there is interest here in the Subaru.
There are a LOT of people who just want to fly cheaply and have fun, so
I'm sure you're going to LOVE that Rebel !

Hope you get lots of requests for the photos for posting here & at
Wray's ....

Not to scare you, but the comment about buying a partly-built kit
reminded me -

Just a thought - for anyone buying a 'almost finished' Rebel -
especially the early ones ....

The old manuals had a 'cut-away' drawing of the fuel tanks which
DID NOT show the stringers in the top of the tank. Some Rebels were
actually built with the top stringers cut out of this area !!! This
would be EXTREMELY dangerous - like cutting the main spars ! PLEASE
inspect this area carefully - there are still some out there like this !
And there are some that were "patched up" when the builders realized the
problem - BEWARE !! This MAY be why they are selling cheap !!

There are ways to do a repair, but it will involve a lot of disassembly
and close work with the factory - they WILL be pleased to help !

Anybody out there with a 912 or a small Subaru who can give Frank
some encouragement about how well the Rebel flies with smaller engines ???
We sure enjoy ours with the 912 !! Cheap FUN flying !! :-)

Hi gang,
I thought it was time to come out of hiding and make myself known. My
name is Frank Arndt and I live in Sarnia, Ont. (about 3hrs west of
Toronto,
right on the US border). I bought 145R in Orangeville, Ont 90% complete
less
engine and hanging way up from the rafters. The workmanship was quite good
in my opinion.
I would like to say that this mail list has been a great resource of
idea's and opinions with your primary aim focused on saftey, which it
should
be. I am starting to feel real guilty for absorbing all your ideas but
offering the list nothing, so here goes:
I am not a "HorsePower nut" so my engine choice would probably not
suit
most people on the list. I have decided to give the Subaru EA-81 a fair
try
at Rebel 145R. I am currently flying a Karatoo (with another EA-81) which
is
overweight 970lbs+ and extreamely nose heavy as the airframe was not
intended for this engine. All that said, it flies not too bad and I figure
I
have to get better performance in 145R. I am almost finished my little
project with some instruments and paint left to do. 145R is relatively
light
(under 800lbs when complete, I hope!) and has all the safety modifications
done. All my flying will be on wheels, most of it solo and I'm not
planning
any round the world trips, just a little air-time is what I am after. I am
hoping my new engine produces 85 to 90 HP, (I don't quite buy the 105HP
advertized) and I would be quite happy bumping along at 80 mph.
I don't want to bore you so I will shutup now.
I would love to hear your thoughts, (good or bad) and if there is anyone
out
there trying to do something similar I have lots of digital JPG's of 145R,
mostly the engine installation. Also I will share all my performance data
(good or bad) so anyone interested will learn from my experience.

Special thanks to Bob Patterson and Dave Bangle for your opinions up front
and honest.

Frank

I guess I can add my two cents, after that invite from Bob as I have the
912 in my Rebel. It wasn`t planned that way but I bought the fully
completed/used Rebel this way because;1-the price was right 2- it's
cheap to fly, operate and maintain as it's reg't as an AULA for one
thing 3-licensing was cheap also since I only needed a U/L.

Rick in Australia didn't beleive you could put floats on this setup, and
while I agree you won't get the performance of an 0-320, I can go pretty
much any place they can cheaper but slower. I call it "the poor man's
plane" but most people think otherwise when they see the plane.

As Bob P. put it, there are a few of us with this setup and we do some
nice slow flying which is enjoyable too. Bye the way, Bob flew mine from
the factory in B.C.back in 93 for the original owner to Northern
Ontario, so he's got almost as much time logged on it as I do.

If I ever have the money, like winning the lotary or something, I might
go for something like the 912S for that little extra Ummmph!!!

Keep us posted of your results with the Suburu.

Great advice as usual Bob,

My experience with the Val Radio are:

Make sure you get a newer model that has a battery in it to retain the
frequency you set. Otherwise ever time you turn it on you have to reset the
frequency! Has caused problems for our chapter while doing Young Eagle
Flights because you concentrate on the kids safety as you taxi out. Then as
you pull out on the runway you broadcast your intentions without noticing
that the radio has defaulted to the bottom of the scale! Has cause some
close calls with aircraft pulling out with another on short final, much to
the excitement of the Parents!

Also, I have found if you are using a Val Radio, you better order a $150cdn
filter to put on the power lead AT the radio. The noise in the headset will
drive you nuts otherwise! (Remember test flying Howards Amphib Bob?) Have
had to filter 2 others also. One in a C150 and another Rebel. My KLX135's
are absolutely silent (for noise that is), but yes you are right, the
original one I bought cost me $4200cdn and the latest one the price was
down
to $2200U.S ($3300cdn).

As for the vacuum instruments are you sure there is a difference?? I have
the same instruments (A/H and D/G) in both Rebels. One with pump and one
with V. tube. All work fine! Maybe I just got lucky?????

Corrosion Protection

Randy, some have epoxy chromated the entire interior of all the parts
(wings, fuselage, tailfeathers, etc.)! Not a bad idea if you are going to be
in Salt Water, but adds significant weight (and $$ at $75/quart). If you are
flying fresh water I would only do the interior of all the tailfeathers and
the rear two or three sections of the fuselage. These are the areas that get
bathed in spray when on floats and may be prone to corrosion. There is lots
in the archives about corrosion proofing so have a look through there!

Hello: Everyone, I am also a new builder, in fact the tail section kit for
the Rebel should be arriving mid February. I plan on putting the Rebel on
Floats and I am trying to make a decision on corrosion protection for the
aircraft. In particular should I prime all of the interior components and
if so with what product. I know Murphy suggests using Zinc chromate on
joints and dipping rivets, but is that enough for the water ( I also hate
Zinc Chromate for spraying) . I am interested in anyone's opinion.

Thanks

Subject: Wing Attach Fittings Paranoia

The Elite is coming along nicely. I'm working on the right
wing after knocking down a wall in my crowded workshop.
But am having an attack of bolt hole edge distance
paranoia.

Things have gone well and I am now fitting the front and
rear spar fittings. These are the fittings that attach the
wing to the fuselage (W-119 and W-124 which I believe are
the same part numbers on the Rebel).

The front and rear spars are pre-punched for placing
the spar fittings. The pre-punched holes at the spar root
have the normal 5/16" edge distance found on most parts.
However, these holes get drilled and reamed for either
AN3 or AN4 bolts which would require at least 3/8" edge
distance (for AN3 bolts).

As these fittings seem *really* small (for attaching something
as important as the wing). And the number of bolts doing
the attaching also seems small, I'm making every attempt
to keep tolerances tight.

The factory parts all seem to be manufactured correctly. I know
there are extra doublers in this area. But why is edge distance
not a problem here, when it seems like you'd *really* like that
extra metal?

Also, the construction in this area does not seem to allow
inspection or replacement of the bolts holding the front spar
fitting. As I'll be on floats, I'd like to be able to inspect
and replace all bolts as they can corrode over time from
water and abuse (especially salt water). Am I misreading
the manual or are these bolts all torque 'em and forget 'em?

I checked Wray's online manual and the Elite looks almost
identical to the Rebel in this area so words of wisdom and
comfort will help me sleep better.

Eric, Torque 'em and Forget 'em, just like a Cessna or any other! Coat
them
with epoxy chromate before installing so the water can't get in there! I
have fixed some pretty good wrecks (if you can call a wreck good). The
wing
fittings have always been in perfect condition (after the fall) and I had
one where the cabin was narrowed at the rear attach fitting by 8", after
the
wing tip dug into the ground. The wing fittings were just fine, although
the
compression of all three torque tubes jamming together cause the opposite
wing to be damaged inside also. The Rebel that went in the lake and
cartwheeled bent the right wing up like a boomerang, but all fittings were
left like new! In most aspects of flight there is a compression load on
the
attach fittings and not tension. Hope this lets you sleep at night now,
Wayne

Subject: Wing Attach Fittings Paranoia

The Elite is coming along nicely. I'm working on the right
wing after knocking down a wall in my crowded workshop.
But am having an attack of bolt hole edge distance
paranoia.

Things have gone well and I am now fitting the front and
rear spar fittings. These are the fittings that attach the
wing to the fuselage (W-119 and W-124 which I believe are
the same part numbers on the Rebel).

The front and rear spars are pre-punched for placing
the spar fittings. The pre-punched holes at the spar root
have the normal 5/16" edge distance found on most parts.
However, these holes get drilled and reamed for either
AN3 or AN4 bolts which would require at least 3/8" edge
distance (for AN3 bolts).

As these fittings seem *really* small (for attaching something
as important as the wing). And the number of bolts doing
the attaching also seems small, I'm making every attempt
to keep tolerances tight.

The factory parts all seem to be manufactured correctly. I know
there are extra doublers in this area. But why is edge distance
not a problem here, when it seems like you'd *really* like that
extra metal?

Also, the construction in this area does not seem to allow
inspection or replacement of the bolts holding the front spar
fitting. As I'll be on floats, I'd like to be able to inspect
and replace all bolts as they can corrode over time from
water and abuse (especially salt water). Am I misreading
the manual or are these bolts all torque 'em and forget 'em?

I checked Wray's online manual and the Elite looks almost
identical to the Rebel in this area so words of wisdom and
comfort will help me sleep better.

Thanks,

Eric Fogelin

Eric,
I have a "spare" Rebel wing out in the hanger and will have a look at it
later tonight (it's -39c so not to keen tonight) or in the morning, to
check
the edge distance. I am working on a SR wing set right now in the shop and
it has very minimal E.D. for the two bolts that hold the Root rib to the
front spar. I know Murphy load tests their wings before offering to the
market (unlike some others) so I wouldn't worry too much about it. The
only
thing to check is that when you put the ribs in place, is the distance
between each rib set equal (for and aft) all the way along, to prove the
predrilled holes are in the right location and that you didn't get a bad
front spar.

Blue skies,

Wayne's right !! The Elite ailerons & flaps are COMPLETELY different

large aerodynamic balance horns at the outboard ends.

Again - they added a lot of weight, complexity for building, and
lost roll effectiveness. Why ?? Because a bunch of potential customers
thought aluminum would look more like a "real airplane" - the old
"Cessna did it, so it must be good" thing !!! ;-(

FWIW on my Rebel the w161 overlaps the leading edge spar (inboard) on both
wings.
On the right wing I just barely have 1/2" edge distance on the leading
edge
spar
for the AN4 bolts. The left wing has quite a bit less. In addition to
Wayne's
comments, I think maybe the spar doublers (.040 and .050?) reduce the need
for
the normal edge distance.

As far as corrosion goes, I chromated over the entire bolt. I asked MAM
about an
inspection/access plate and they said no, which I guess is not surprising
in
this area. I believe I had to insert the bolts with the head forward to
clear
the wing skin so there would be no way to remove them anyway.

There is a similar situation at the rear spar where the width of the
flange
on
the root rib is not sufficient for the normal edge distance. I am sure
that
MAM
has designed for this as well however.

cheers
Ken

Hi gang,
I thought it was time to come out of hiding and make myself known. My
name is Frank Arndt and I live in Sarnia, Ont. (about 3hrs west of
Toronto,
right on the US border). I bought 145R in Orangeville, Ont 90% complete
less
engine and hanging way up from the rafters. The workmanship was quite good
in my opinion.
I would like to say that this mail list has been a great resource of
idea's and opinions with your primary aim focused on saftey, which it
should
be. I am starting to feel real guilty for absorbing all your ideas but
offering the list nothing, so here goes:
I am not a "HorsePower nut" so my engine choice would probably not
suit
most people on the list. I have decided to give the Subaru EA-81 a fair
try
at Rebel 145R. I am currently flying a Karatoo (with another EA-81) which
is
overweight 970lbs+ and extreamely nose heavy as the airframe was not
intended for this engine. All that said, it flies not too bad and I figure
I
have to get better performance in 145R. I am almost finished my little
project with some instruments and paint left to do. 145R is relatively
light
(under 800lbs when complete, I hope!) and has all the safety modifications
done. All my flying will be on wheels, most of it solo and I'm not
planning
any round the world trips, just a little air-time is what I am after. I am
hoping my new engine produces 85 to 90 HP, (I don't quite buy the 105HP
advertized) and I would be quite happy bumping along at 80 mph.
I don't want to bore you so I will shutup now.
I would love to hear your thoughts, (good or bad) and if there is anyone
out
there trying to do something similar I have lots of digital JPG's of 145R,
mostly the engine installation. Also I will share all my performance data
(good or bad) so anyone interested will learn from my experience.

Special thanks to Bob Patterson and Dave Bangle for your opinions up front
and honest.

Clay,
I am also working on instrument panel stuff. Aircraft spruce offers a
line of
2 1/4 " gauges that are supposedly vibration resistant. They are their
Microflite-1000 series. I have bought some of them and will try them out.
Mechanical oil press, mechanical oil temp, and voltmeter are the ones
that
I
purchased. Their ammeter is only a 30 amp so I got a Westach with a 60 amp
+
shunt. The Microflight-1000's are fairly inexpensive and had a good
description
of them in the catalog. They look nice too. Check their web site it may
have the
same info. I have a vibration isolated main panel for the standard six
pack
of
instruments and have not bought any of those yet. I also think that I will
isolate the small panel. The small 8-32 stud mounted shock isolators work
for me.
Same as Cessna panel mounts.
Good luck,

Well said Rick,
Howard just loves his electronic (all in one, with the flashing red idiot
light) engine monitor. I won't name the brand. He did however have his
plane
tied to the dock for 2 days this summer, while he tried to get a hold of
the
manufacturer as all readouts were away off so he couldn't fly. On the 3rd
day he had me come up to the lake and with the owner of the Electronic
Company on the other end of the phone line, I reprogrammed his "hidden"
set
up pages that had been zapped by a power surge due, to starting up with
the
monitor turned on! Good thing he was tied to his own dock! But if you were
in the boonies, I guess if you know your plane well enough and that it
normally doesn't redline on takeoff, etc and temperatures/pressures
usually
run normal you could chance flying to civilization. (NOT With me along for
the ride you won't) Or you do carry all the info and programming sheets
that
come with everything you are putting in the plane don't you! This will
allow
you to use you Cell Phone and call the manufacturer from Lake Timbucktwo.
What, no signal you say!!!! You did bring paddles, didn't you????

I guess I'm just an Analog type of guy also! (I did say Analog)

Nothing leaps to mind - most are ok. Are you planning on having any
gyro instruments ?? Vacuum or electric ?? There ARE differences between
vacuum gyros meant for vacuum pumps, and those for venturi tubes - get
the wrong one, and it won't work properly !! Personally, I dislike
vacuum pumps - they suck about 3 hp. all the time, and need overhaul
too often for my liking. Venturi tubes won't hurt much - it's not
a 300 mph. airplane ! :-) If you don't plan IFR anyway, then maybe
just a standby electric turn-and-bank, just in case ! ;-)

Vertical card compasses are nice, but expensive - probably not worth
the price ... If you can find a good one at Canadian Tire - go for it !
At a recent Rebel Builders meeting, we heard about a new type of compass
that's available through Radio Shack for about $60 - electronic, and
easy to set up, even with extreme magnetic conditions (like steel tube
next to compass).

Get an airspeed indicator that covers your range as close as possible
- markings down to 20 mph, and up to 140 or 160, although even 130 would
likely do. Avoid the 250 mph types - too hard to read the 1" needle range
:-)
Many Rebel Builders are using the VAL panel mount radio - they cost
less than a hand held, and give good performance (8 watts), and have a
bright display that adjusts for lighting conditions. They have a 2 channel
flip flop switch which is handy for going to ground control quickly.
For about $75 extra, they will supply a made-up wiring harness, ready
to go - a bargain !

Hand-held GPS, with a bracket on the panel, is the most
cost-effective
way to go. The technology is advancing quickly, so wait as long as you
can to buy - prices are falling. The fancy combination radio & GPS units
look sexy, but they're EXPENSIVE - both to buy, and maintain. If one
part goes, you lose both for servicing :-(

A moving map display is really nice, but we fly one Rebel with a
$140 GPS from the sporting goods store - works way better than our old
LORAN !! You can always move up, when you know what you want ...

You might want to check out photos of other panels - the standard
layout is becoming - electrical stuff on left angle panel, mounted on
a flip down panel with piano hinges top & bottom, with a doubler around
the hole. The flight instruments are often mounted on a floating panel
in front of the pilot - use 1/8" Lexan for this, and you can put labels
on the back, and paint the back. This looks great, and is protected.
The floating panel is mounted on shock mounts (or just bolts with
fuel line over them). Cut holes in the metal panel to match the floating
panel, but oversize about 1/4" or so - to keep the strength of the
panel (it IS structural). Attach a 1 1/2" aluminum angle to the bottom
of the panel - all the way across, and even out the angles. This angle
will stiffen up the panel AND give you a plave to mount the throttle,
mixture, carb heat, primer, and trim button, leaving space for 2 rows
of full sized instruments on the panel. (can be a 2" angle)

Glad you spoke up !! I'm sure there is interest here in the Subaru.
There are a LOT of people who just want to fly cheaply and have fun, so
I'm sure you're going to LOVE that Rebel !

Hope you get lots of requests for the photos for posting here & at
Wray's ....

Not to scare you, but the comment about buying a partly-built kit
reminded me -

Just a thought - for anyone buying a 'almost finished' Rebel -
especially the early ones ....

The old manuals had a 'cut-away' drawing of the fuel tanks which
DID NOT show the stringers in the top of the tank. Some Rebels were
actually built with the top stringers cut out of this area !!! This
would be EXTREMELY dangerous - like cutting the main spars ! PLEASE
inspect this area carefully - there are still some out there like this !
And there are some that were "patched up" when the builders realized the
problem - BEWARE !! This MAY be why they are selling cheap !!

There are ways to do a repair, but it will involve a lot of
disassembly
and close work with the factory - they WILL be pleased to help !

Anybody out there with a 912 or a small Subaru who can give Frank
some encouragement about how well the Rebel flies with smaller engines ???
We sure enjoy ours with the 912 !! Cheap FUN flying !! :-)

I guess I can add my two cents, after that invite from Bob as I have the
912 in my Rebel. It wasn`t planned that way but I bought the fully
completed/used Rebel this way because;1-the price was right 2- it's
cheap to fly, operate and maintain as it's reg't as an AULA for one
thing 3-licensing was cheap also since I only needed a U/L.

Rick in Australia didn't beleive you could put floats on this setup, and
while I agree you won't get the performance of an 0-320, I can go pretty
much any place they can cheaper but slower. I call it "the poor man's
plane" but most people think otherwise when they see the plane.

As Bob P. put it, there are a few of us with this setup and we do some
nice slow flying which is enjoyable too. Bye the way, Bob flew mine from
the factory in B.C.back in 93 for the original owner to Northern
Ontario, so he's got almost as much time logged on it as I do.

If I ever have the money, like winning the lotary or something, I might
go for something like the 912S for that little extra Ummmph!!!

Keep us posted of your results with the Suburu.

Great advice as usual Bob,

My experience with the Val Radio are:

Make sure you get a newer model that has a battery in it to retain the
frequency you set. Otherwise ever time you turn it on you have to reset
the
frequency! Has caused problems for our chapter while doing Young Eagle
Flights because you concentrate on the kids safety as you taxi out. Then
as
you pull out on the runway you broadcast your intentions without noticing
that the radio has defaulted to the bottom of the scale! Has cause some
close calls with aircraft pulling out with another on short final, much to
the excitement of the Parents!

Also, I have found if you are using a Val Radio, you better order a
$150cdn
filter to put on the power lead AT the radio. The noise in the headset
will
drive you nuts otherwise! (Remember test flying Howards Amphib Bob?) Have
had to filter 2 others also. One in a C150 and another Rebel. My KLX135's
are absolutely silent (for noise that is), but yes you are right, the
original one I bought cost me $4200cdn and the latest one the price was
down
to $2200U.S ($3300cdn).

As for the vacuum instruments are you sure there is a difference?? I have
the same instruments (A/H and D/G) in both Rebels. One with pump and one
with V. tube. All work fine! Maybe I just got lucky?????

Nothing leaps to mind - most are ok. Are you planning on having any
gyro instruments ?? Vacuum or electric ?? There ARE differences between
vacuum gyros meant for vacuum pumps, and those for venturi tubes - get
the wrong one, and it won't work properly !! Personally, I dislike
vacuum pumps - they suck about 3 hp. all the time, and need overhaul
too often for my liking. Venturi tubes won't hurt much - it's not
a 300 mph. airplane ! :-) If you don't plan IFR anyway, then maybe
just a standby electric turn-and-bank, just in case ! ;-)

Vertical card compasses are nice, but expensive - probably not worth
the price ... If you can find a good one at Canadian Tire - go for it !
At a recent Rebel Builders meeting, we heard about a new type o

Corrosion Protection

Posted: Fri Feb 17, 2012 5:40 pm
by Bob Patterson
I agree with Wayne ! The tailfeathers are important, as they are the
lowest area, on wheels, anyway. The inside bottom of the fuselage does
accumulate a lot of water, sometimes just condensation.

One tip - to help with drainage, even on wheels, we drilled a small
(1/16 - 1/8) hole in the bottom skins, just in front of each bulkhead
in the rear fuse. Decided to do this after finding several POUNDS of
ice in this area after a month of snow, freezing and thawing, and water
trickling in ... !!!!! This is NOT good for C of G !! :-(

For the same reason, seaplane-style drain grommets are a good idea
on the flapperons - and to get some air flow inside, to prevent corrosion.

As Wayne says, use the factory-recommended chemistry - Polyfibre
Epoxy Chromate - not just any old 'zinc chromate' product !

Hello: Everyone, I am also a new builder, in fact the tail section kit for
the Rebel should be arriving mid February. I plan on putting the Rebel on
Floats and I am trying to make a decision on corrosion protection for the

Did the air-aba inspector not snag the plane for lack of drain holes in the
belly?? That was the first thing Lawrence looked for on mine!(and yes they

Bob, I knew to drill drains in mine, only because of the fact that one day I
picked at a hunk of dirt on the belly of my C182. (remember the ugly
duckling). It turned out this was a drain hole and we watched it drain for
over 1/2 an hour. Probably 30 gallons of water! This was of course followed
by a good spray of corrosion inhibitor thru every access hole in the floor!

I have decided to cromate the interior parts of my rebel. Has any one had
experience with the products aircraft spruce sells. For example there are
several metal prep products listed.

1- improved metal prep no.79
2- alodine no. 1201

Or does any one know of a simplier way to prep aluminum for cromating?
Also are scotch abrasive pads available at Home depot and do I need them as
some builders have said?

Hi MIke.

I found that Alumaprep etch followed by Alodine does a better job faster
(than Scotchbrite) on some of the more complicated pieces like the ribs and
wing stringers or big areas like the wing skins. I used tap water followed
by distilled water for the final rinse and then wiped and let dry for a
couple of hours. It took the epoxy chromate well.
I chromated everything, not just seams, probably an overkill. Later on to
save time I just used the Alumaprep etch, (skipped Alodine), rinsed, dried
and chromated. It also took the chromate well.
In either case, (chemicals or Scotchbrite) you must degrease first. The
plastic protective film leaves a coating that must be removed. (What a pain
pulling all that plastic off the wing skins!!!!)
I did the chemical stuff in a plastic tank or a plastic evestrough for the
long pieces.
With Scotchbrite dust is a problem but it is faster especially on smaller
flat pieces.
I am priming only seams and areas that become inaccessible. In the fuse I
will do only seams and the floor. Anything visible can be done later if
necessary.

Hope this helps!

Mike

I degreased with acetone, then a quick scotch-brite scrub with metal prep on the
exterior (do it in sections and rinse with a hose), then epoxy primer. I did
not use the metal prep on the interior. The metal prep is diluted 4:1 with water
so a quart is enough for the whole airplane and I was impressed with its
effectiveness and ease of use. You get both a chemical etch this way and a
mechanical "etch" from the scotch brite.

For the interior fuselage I took my chances on scotch-brite alone followed by
acetone degrease. Use a very light coat of primer. It would have been easier to
do the panels before assembly but it wasn't too bad with an hvlp sprayer. I left
my wing interior bare but will spray Corrosion-X or ACF-50 oil after painting
the exterior.

I refused to do the alodine for environmental reasons.

I get the fine (maroon) scotch brite pads from Princess Auto (cheap) or an
industrial supplier at about cdn $0.80 ea. for 6" x 9" and cut them into 3
smaller pieces.

you or someone else could clarify the process. I have a flying Rebel and it
is primarely unpainted, just a pin stripe job. About 12-18 months ago I did
use Alumaprep followed by Alodine and did use a scocth pad with one or both
of these. At the time, I thought it looked O.K. but it now appears very
streaky.

Am I using the right products, you mentioned an Alumaprep ecth. Is this a
different product. Do you think my problem is maybe it dried before I rinsed
or didn't rinse thoroughly enough.

Any help would be appreciated. Keep in mind, I will be leaving it unpainted
and do use floats. Can't affor any extra weight !!!

corrosion protection

Posted: Fri Feb 17, 2012 5:46 pm
by C&P Kucera
Hi Aurele.

I used chemicals on inside surfaces only so far. I noticed different shades
of gold after Alodine. It varied with time of exposure.
I did not get streaking but I would think if the Alumaprep evaporated before
rinse it could do it.
I am not messing with Alodine any more. It is an environmental problem. As
far as corrosion protection goes I think the epoxy chromate is more
effective anyway.
The Alumaprep etch is OK as it is only diluted phosphoric acid, (also found
in pop and food!!!....scary!!)

I am also going on floats but I will paint the exterior with grey color
close to the natural aluminum. That way the coat will not have to be too
thick and heavy. To brighten it up I will add a dab of color here and there,
tail/wing tips, graphics etc.......let my son put on some Pokemon
stickers!!! (just kidding...but then maybe???).
Some gray paints contain aluminum powder to give it that metallic look. This
is very difficult to apply with pleasing results and should probably be left
to the pros.
If I decide to paint myself I will go for non metallic paint.

Happy flying!

Paul Kucera,

Streetsville, Ont.

Am I using the right products, you mentioned an Alumaprep ecth. Is this a
different product. Do you think my problem is maybe it dried before I
rinsed
or didn't rinse thoroughly enough.

Any help would be appreciated. Keep in mind, I will be leaving it
unpainted
and do use floats. Can't affor any extra weight !!!

Thanks, Aurele

Hi MIke.

I found that Alumaprep etch followed by Alodine does a better job faster
(than Scotchbrite) on some of the more complicated pieces like the ribs
and
wing stringers or big areas like the wing skins. I used tap water
followed
by distilled water for the final rinse and then wiped and let dry for a
couple of hours. It took the epoxy chromate well.
I chromated everything, not just seams, probably an overkill. Later on
to
save time I just used the Alumaprep etch, (skipped Alodine), rinsed,
dried
and chromated. It also took the chromate well.
In either case, (chemicals or Scotchbrite) you must degrease first. The
plastic protective film leaves a coating that must be removed. (What a
pain
pulling all that plastic off the wing skins!!!!)
I did the chemical stuff in a plastic tank or a plastic evestrough for
the
long pieces.
With Scotchbrite dust is a problem but it is faster especially on
smaller
flat pieces.
I am priming only seams and areas that become inaccessible. In the fuse
I
will do only seams and the floor. Anything visible can be done later if
necessary.

Hope this helps!

I have decided to cromate the interior parts of my rebel. Has any one
had
experience with the products aircraft spruce sells. For example there
are
several metal prep products listed.

1- improved metal prep no.79
2- alodine no. 1201

Or does any one know of a simplier way to prep aluminum for cromating?
Also are scotch abrasive pads available at Home depot and do I need
them
as
some builders have said?

Mike,
If you are going to spray the Polyfiber Epoxy Chromate Primer on the
large inside surfaces, you need only wipe them down with Metal-Sol first,
and spray a VERY thin coat - you should be able to read the lettering
on the aluminum through it ! Anything thicker will add weight, and
might even be thick enough to crack, allowing moisture penetration.

Be sure to use a proper forced-air hood for spraying, as this stuff
can be fatal if it gets into your lungs as a spray !

If you are going to spray parts which have already been put together
with wet Epoxy Chromate Primer, be careful not to flood the surface
with Metal-Sol, or you might dissolve some of the existing Primer in
the joints.

Etching and Alodine treating is an alternative, but Alodine is
an environmental hazard, and hard to dispose of. This method is no
longer a popular solution....

A couple of good points, Ken !! Acetone is probably a better choice
than Metal-Sol or MEK - it isn't nearly as hard on the liver, kidneys,
and lungs !! It also gets rid of any water very effectively.

Stay tuned - I learned about a new NON TOXIC degreaser at Sun 'n Fun
and will soon have sources. It's called Citrus-Safe (or something like
that), is VERY effective, leaves no residue, doesn't hurt the environment,
and is now being used by Boeing !! It IS, however, very pricey - BUT
I am checking a "equivalent" product that is much cheaper in bulk ...

The builder who told me about it said he weighed the cost of a
new liver and decided this stuff was a bargain !! ;-)

The Northern Shield corrosion prevention system would be a better
and cheaper solution than ACF-50, which is messy, drips off, and must
be re-done frequently. Northern Shield goes in as a mist, penetrates,
and sets up to a waxy finish in a few days, so only has to be done
once - and it costs under $50 to do the whole aircraft ...
(we had a presentation on it at a meeting a few years ago ..)

I degreased with acetone, then a quick scotch-brite scrub with metal prep
on the
exterior (do it in sections and rinse with a hose), then epoxy primer. I did
not use the metal prep on the interior. The metal prep is diluted 4:1 with
water
so a quart is enough for the whole airplane and I was impressed with its
effectiveness and ease of use. You get both a chemical etch this way and a
mechanical "etch" from the scotch brite.

For the interior fuselage I took my chances on scotch-brite alone followed by
acetone degrease. Use a very light coat of primer. It would have been easier to
do the panels before assembly but it wasn't too bad with an hvlp sprayer. I
left
my wing interior bare but will spray Corrosion-X or ACF-50 oil after painting
the exterior.

I refused to do the alodine for environmental reasons.

I get the fine (maroon) scotch brite pads from Princess Auto (cheap) or an
industrial supplier at about cdn $0.80 ea. for 6" x 9" and cut them into 3
smaller pieces.

Aurele,
It's normal for an Alodine job to be streaky - it's almost
impossible to get the coating even enough not to get streaks !

Alodine treatment is usually either inside, in non-visible places,
or used before painting. There's not much you can do on the outside
except a primer coat and a light coat of paint - you're right, though -
you will gain at least 25 to 35 pounds !!

Bob, see you landed safely somewhere as I see your laptop is working.
Further to your note, would it be a good idea for me to scrub the rebel down
with Aluminaprep and pad to remove these streaks and then is there anything
I can use for protection. You mentioned primer..., but waht about the
Northern Sheilds stuff you mentioned. If so, where do get this stuff? It
sounds like it is cheap, easy to apply and doesn't add much weight. Would it
laso be good for the interior, especially the tail section. I don't know
what was done to this aircraft when first built.

Thanks Bob,

Aurele Lavigne
