Borer Prop for Rebel on Floats

Post by Wayne G. O'Shea » Fri Feb 17, 2012 11:58 pm

The McCauley Borer is obtainable in 81" and 82" lengths with a very flat
pitch usually between 41 and 43 for the 150 to 160 HP engines. Read TIP
NOISE!! and a bigger drag disc out front. Pull the power back and it's like
putting on the brakes in the air. Great for nosing down into some really
short bush strips, but lots of $$$$ if you can't find a GOOD used one and
cruise WILL suffer. Then again none of us are in a hurry (until there is a
front chasing us home!!).

Borer Prop for Rebel on Floats

That's why the cub guys run 29 and 31" Bushwheels, to get it up out of the
grass (in addition to 3" and 6" gear leg extensions!).

The Borer's for the 0320 are generally about 82 X 41 or 42. It's
that extra diameter that provides so much extra thrust for
take-off which is what you want on floats. There is a trade off,
of course, and that is less cruise. However, since float planes
are slower anyways, the difference isn't always that much. You
might have to turn 2450 instead of 2350 to get 65 % power and
still get almost the same cruise. That's what I'm trying to find
out. However, there must be a good reason that so many Supercubs
on floats with the 0320 use this prop.

I am not sure I would want to use this prop on wheels, though,
unless you wanted to use it to mow your runway grass.

I have to agree with you, but the fellow that owns the
kit talked to some
one
at one of the float companys and they highly
recomended the Borer for float
flying. And he found (a deal) on the one that was
recomended. And the rest
is
history. We'll see some time next year (IF) I can hang

Borer Prop for Rebel on Floats

Post by Legeorgen » Fri Feb 17, 2012 11:58 pm

Walter,

Your friend with the Rebel that can't keep up. Does he have the same prop on
his 0320 160HP Lyc. as you on your 150HP? How can there be that big of a
difference? you have to be 10-15 MPH slower on amphibs.

If the borer only cost you 5 MPH it would be well worth the trade. How about
the Horner tips, STOL kit AND Borer prop? That would be one Rebel on Steroids.

Yup, that's what I have been thinking.

Can't remember what that STOL kit weighed, though. If it is more
than 20 pounds, I would be concerned, as an 0360 is only about 30
pounds more than the 0320, and I would take that extra 30 hp
first if the weight is the same. It's too bad MAM doesn't offer a
STOL leading edge rib option, so you wouldn't have the weight
penalty.

I can only get about 100mph out of mine on floats with the 0-290 on wheels
it'll do a little over 130. you're making me green with envy Walter.

Post by Walter Klatt » Fri Feb 17, 2012 11:58 pm

Wow, 30 mph is a huge difference to lose on floats. Are you able
to turn 2700 on floats? Also, what is your angle of incidence on
the float mounting. Mine is -2.5 degrees. Earlier installations
used 2 degrees, and I seem to recall when some people (Wayne?)
switched to 2.5, their speed increased as well. I think it has to
do with taking some lift and therefore drag out of the floats
with the higher angle of incidence. The main benefit is faster
take-offs on water, but extra speed is good, too. During the
winter sometime, I would like to drop my back struts one more
hole, and try 3 degrees to see how that works. Not sure if anyone
else has done that yet.

Borer Prop for Rebel on Floats

Post by mike.davis » Fri Feb 17, 2012 11:58 pm

There's a picture on the MAM web site somewhere of a Rebel sitting on a frozen
lake in Alaska titled "one tired Rebel"... it has 29" baloon tires on it.
That Rebel was up here in North Pole this summer, or was it last... anyway, he
had an 81" prop on it, and from the stories he shared with me did not have
trouble with it in the bush with those big tires. Apparently with that prop
on it he routinely showed up his supercub driving friends. I think he said he
cruised around 90 mph.

Borer Prop for Rebel on Floats

Post by Walter Klatt » Sat Feb 18, 2012 12:00 am

Bob, I agree his lack of fairing on the gear legs can make some
of that difference, but I had mine initially that way for a short
while, too, and I'm sure I was getting more than 120 mph.

Good to hear that the STOL kit is only 13 pounds, and with that
difference in stall speed, could be a very worthwhile
improvement. Sure would like to hear more about the float guys,
what that did to their take-off times and distances off the
water. That's where it should make the biggest difference.

I may have to contact the Fife guy, although I hate to replace
perfectly good tips, complete with lights and strobes. If those
are the numbers, I'm interested.

Do you know which constant speed prop the 0360 guy was going to
use? That should definitely be a hot performer on floats.

Hi Walter !

"He has the bungee gear, but the leg struts are open" ...

That's his problem !! We found that proper fairing on
the gear legs and bungee struts could give at least another
10 mph !! Definitely worth doing !!

The STOL kit adds only 13 lb., and the Fife Hoerner
wing tips are worth doing, even though you already have tips.
I took my original tips off and installed Dave's - VERY easy,
as they just slip on !! :-) This is THE easiest, fastest
performance improvement for the Rebel !

Thought Curt would chime in with the numbers - they did
very detailed testing of the tips, measuring takeoff distance,
and timed runs in several directions, using GPS for
cross-reference.
They then landed and changed tips, added fuel to the
same weight,
and went out & did it all again - tough job !! ;-)

As I recall, the takeoff distance numbers were
something
like 390 ft. with the factory tips, and 295 ft. with
the Hoerner
tips .... please correct me here Curt or Dave ! Think the
stall went down 2 mph...

I didn't do anything so scientific - just by feel, the
Rebel felt lighter and took off in less distance with the new
tips. Climb was better by about 100 feet/min., and low speed
controllability was definitely better. Cruise was the same,
but you definitely need the 2 notches of negative flapperon -
the extra lift is really noticeable !

Angus makes no performance improvement claims for the
STOL kit - just safer flying ! My experience was a 10
mph reduction
in stall speed, and the ability to climb safely at 800 fpm at
46 mph indicated !!!! There was no noticeable
decrease in cruise.
With the kit, you could just drag it in slowly with
lots of power,
and land VERY short. I haven't got the nerve for that
at this point,
but some of the very experienced Rebel float pilots
are going into
'lakes' that are only 900 feet long, with both the tips and the
STOL kit !!

As for the 180 hp. - that <30 lb. more> is
highly suspect,
given the accuracy of Lycomings engine weights in the past !
We'll see next year, as a nearby builder has decided to use
an XP-360 Superior 180 hp. engine - with a composite
constant speed
prop ! Whole package is supposed to weigh only about 12 lb.
more than an O-320/Sensenich combination !! The
scales will tell !! ;-)
Guess, with the firewall moved back, and ALL of the beef-ups,
this MIGHT be a good combination - sure will be THE
hottest performer
around !!! Only time will tell about durability, but the
weight will be the key factor ...

producing 160

throttle, which is what I get. Anyway, I would start
leaving him
behind at about 120 mph while I would go up to 125
with 2 people
and floats. I can't remember what I was on wheels, but I think
around 135 for top speed.

Walter,

Your friend with the Rebel that can't keep up. Does he
have the same prop on
his 0320 160HP Lyc. as you on your 150HP? How can
there be that big of a
difference? you have to be 10-15 MPH slower on amphibs.

Borer Prop for Rebel on Floats

Wow, 30 mph is a huge difference to lose on floats. Are you able
to turn 2700 on floats? Also, what is your angle of incidence on
the float mounting. Mine is -2.5 degrees. Earlier installations
used 2 degrees, and I seem to recall when some people (Wayne?)
switched to 2.5, their speed increased as well. I think it has to
do with taking some lift and therefore drag out of the floats
with the higher angle of incidence. The main benefit is faster
take-offs on water, but extra speed is good, too. During the
winter sometime, I would like to drop my back struts one more
hole, and try 3 degrees to see how that works. Not sure if anyone
else has done that yet.

Walter
Can't remember what I set the incidence at. I believe I just used the
numbers from murphy though. I took 1/2a degree of pitch out of my warp
drive and that lets the engine turn up to redline. I think the 0-290 just
isn't enough engine for the plane on floats.

Hi Phil !

It will be interesting to see how it works ! I think
they are so popular with Super Cub pilots is - that's about the
only LEGAL choice they have to improve performance... ;-)
(unlike us lucky Rebel builders !!! :-) )

I have to agree with you, but the fellow that owns the kit talked to some one
at one of the float companys and they highly recomended the Borer for float
flying. And he found (a deal) on the one that was recomended. And the rest is
history. We'll see some time next year (IF) I can hang in there that long.

(BOTH are less $$$$ than a Borer prop, and are a

Borer Prop for Rebel on Floats

The STOL kit can't weigh that much. It's only like an extra layer of leading
edge skins. Well, maybe it can act as the thicker Elite leading edge and
increase the gross to 1850 lb. Unofficially of course.
