Heard of them - don't know anybody who's used one ...

Surely the GSC variable pitch prop would be the best choice for the
912-S !!!

Thanks for the info guys. I thought I had things figured out, but it appears that most of you prefer a two blade vs three and the GSC mechanical seems to be getting good praise. I'm now leaning in this direction.

Bob, I was also concerned about the wooden prop on floats and it appears severall owners are using these with no apparant problems. I'm not sure if Ivoprop has resolved some of the problems mentioened, but I wasn't looking at the Magnum since I have the 912 and was considering the ultralight model. The guy who has one in my area never mentioned and problems with blades, just to order extra brushes.

If that GSC works as my as my current 72", and also allows me to maximize take-off, I'm definetly going to be looking at this option, besides I want to improve performance all around without having to spend a fortune.

I guess the next thing I'll haveto look into are Angus' stol kits and those Hoerner tips. Mike Jones was mentionning this just the other day and I know this is becoming popular and you've had theseguys at your Brampton meetings. I'll talk to you later about these options.

Bye for now, Aurele

The epoxy leading edge seems to protect the blades on the GSC very
well. I think the variable pitch model is about $1,500 - considerably
less than some .... (you might be able to order it through Murphy, for
a bit better deal, or faster delivery ..)

The Hoerner wing tips have reduced takeoff distance by over 20 %,
in real-life tests ! The McKenzie STOL kit is proving VERY popular -
Carmon Titus reported making an approach to a lake at 36 MPH !! He had
to use the GPS, because the airspeed needle had dropped to ZERO !! :-)
He got MANY comments from the people on the shore !!!

Keep us posted on the prop !

Thanks to Bob P. and the others for your input regarding my inquiries on prop choices. I finally decided on the Ivoprop, 3 blade in-flight adjustable for two main reasons; one the weight, being a 912 and second the price. The two blade magnum was twice the weight and more money.

As for GSC's GTA it was a close second,but at $1,500 U.S. , it was almost twice the price of the Ivoprop. Bob, I'm not sure why W.D.'s is painted black but mine shows no faiding.

Once I recieve my prop, I may be selling my WD 3 blade with nickel leading edge and keep my 2 blade GSC as a spare if anyone is looking for a prop at a fair price.

While we are on Propellors, I just removed a like new McCauley propellor / spacer / bolts and Murphy 13" Speed Spinner SET from a Customer's Murphy Rebel. The Propellor worked absolutely beautiful IMHO, but customer wanted to spend $3000 plus for a new Sensenich propellor / spacer and new spinner (plus 8 hours labour), to try and tweak a couple more FPM out of his Amphib Rebel. Who am I to argue with him?

Selling as a complete bolt on set for only for $2000CDN or Best offer. Propellor is a McCauley 1C172-TM7653 (repitched to 50) KlipTip and it only has 140 hours on it SMOH by Hope Propellor in Mississauga. Complete with 1 1/2" McCauley spacer and bolt set. Pattern is SAE #2 and 7/16" bolts as removed from O-320-E2D Lycoming. Spinner is ready to install and back plate is still between spacer and propellor. Entire assembly weighs 33 pounds.(about 9 less than a Sensenich) Spinner was originally installed by myself and has thrust face fillets for the clean look and better aerodynamics. Those that don't know and to see where some of the value is located in this "set", MAM's spinner comes as a "blank" full spinner with no prop cut outs. You must cut out the propellor blade areas, drill the propellor bolt hole "circle" and do the bulkhead anchor nuts etc. I have done numerous spinners and they take me just over 7 hours/set to complete. This spinner also has the rear area behind the blades filled with "thrust face fillets" to close up the gaps and keep the bugs and birds out of the spinner. The 6 propellor bolts will set you back $240 CDN from any propellor shop, etc.

Also have a Brand New Sensenich Propellor Spacer. Model SPM7S9 (for DM7 propellor). SAE #2 X 7/16 bolts. 2 1/4" thick. Sensenich customs papers on 2" replacement spacer show Value of $500 U.S. Will sell for $500CDN or best offer.

Also have a 3 Blade GSC wooden propellor (does not have epoxy leading edges) 70" diameter, bolt pattern is 75MM diameter X 8MM bolts for Rotax 912UL. 10 hours Total Time. Customer replaced with Warp Drive Propellor for float operations. I don't recommend it for a Rebel, but if anyone knows someone with a Zenair CH701 or Pegastol aircraft it would be perfect for it!

Anyone interested send me mail direct to oifa@irishfield.on.ca (oifa@irishfield.on.ca)

Aurele,
I'm ASTOUNDED !!! You're saying that the 3 blade IVO in-flight
variable prop is only $750 USD ??? That's VERY hard to resist .....

I understand that the IVO can be changed to a 2 blade in a matter
of minutes, just removing a blade & installing a spacer ...??

The early Magnums had problems with blade cracking, but that has
been solved, apparently. Is this prop you are getting a 'lightweight'
version of the Magnum, with electric controls ?

Warp Drive props aren't painted black - that is the natural colour
of the carbon fiber material. It wouldn't likely fade, just gradually
disintegrate as the UV ate the bonding material.... Haven't seen this YET,
but it might account for some W-D's shedding blades...

Please keep us posted on progress - how it was to install, and
how it works for you !

Thanks !! .....bobp

Re: IvoProps -- I'm not sure what the natural color of the carbon fiber in
the prop is, I assume black, but having just "touched up" a few stone chips,
the black that you see is a colorant in the gell coat that covers the
structural carbon fiber sheath. The internal of the blades (other than the
super-cam mechanism, etc.) is a pink high density foam.

That $750 price sounds mighty suspicious for a >>Magnum<< >>In flight
adjustable<<.

They make props for planes & air-boats. For aircraft there are 3 sizes:
Ultralight, Medium, and Magnum. I understand each size is available as a 2
blade or 3 blade prop and either in-filght or ground adjustable.

Best to check out their site: http://www.ivoprop.com/

My problem at the moment is finding an approved method of affixing a spinner
over the motor. Any sugesstions? (That can be repeated in mixed company, I
mean.)

Cheers,

Tom

Tom,
The Warp Drive props are solid carbon fiber, no core. They don't
have that nice gel-coat.

Took your advice & checked IVO's web site - it sounds like the
prop in question is an "ultralight" model - might not be up to heavy
use. In any case, the 2 blade, 72", would be a better choice than the
3 blade, & cheaper !

The web site shows a cutaway of just the spinner you're looking
for ! It shows a different end plate on the motor, using those bolts
to hold it on. The end plate has a huge socket in it for a screw which
holds the spinner on. There is also a backing plate shown ! Maybe
IVO sells this assembly ???

Bob, you're right, it is a great price. This is the Ultralight model and
while it can be converted to 2 blades, they are two thin to be used in this
configuration and that's why they recommended their three blade. The two
blade magnum was their next suggestion but at twice the weight and much more
money.

I expect this 68" 3 blade to compare to my WD, wieght and length being very
similar despite the differences in construction. If I add the benefits of
pitch adjustment, it will be well worth the money. I only expect to get it
in 4 to 5 weeks, plus timeto install and will letyou know how I make out.

Bob, you're right, it is a great price. This is the Ultralight model and
while it can be converted to 2 blades, they are two thin to be used in this
configuration and that's why they recommended their three blade. The two
blade magnum was their next suggestion but at twice the weight and much more
money.

I expect this 68" 3 blade to compare to my WD, wieght and length being very
similar despite the differences in construction. If I add the benefits of
pitch adjustment, it will be well worth the money. I only expect to get it
in 4 to 5 weeks, plus timeto install and will letyou know how I make out.

Tom,
The Warp Drive props are solid carbon fiber, no core. They don't
have that nice gel-coat.

Took your advice & checked IVO's web site - it sounds like the
prop in question is an "ultralight" model - might not be up to heavy
use. In any case, the 2 blade, 72", would be a better choice than the
3 blade, & cheaper !

The web site shows a cutaway of just the spinner you're looking
for ! It shows a different end plate on the motor, using those bolts
to hold it on. The end plate has a huge socket in it for a screw which
holds the spinner on. There is also a backing plate shown ! Maybe
IVO sells this assembly ???

Re: IvoProps -- I'm not sure what the natural color of the carbon fiber

in

the prop is, I assume black, but having just "touched up" a few stone

chips,

the black that you see is a colorant in the gell coat that covers the
structural carbon fiber sheath. The internal of the blades (other than

the

super-cam mechanism, etc.) is a pink high density foam.

That $750 price sounds mighty suspicious for a >>Magnum<< >>In flight
adjustable<<.

They make props for planes & air-boats. For aircraft there are 3 sizes:
Ultralight, Medium, and Magnum. I understand each size is available as a

2

blade or 3 blade prop and either in-filght or ground adjustable.

Best to check out their site: http://www.ivoprop.com/

My problem at the moment is finding an approved method of affixing a

spinner

over the motor. Any sugesstions? (That can be repeated in mixed

company, I

mean.)

Cheers,

Tom

Bob,

I fell for that mini spinner pic as well, but it's for the ultralight model
(even though it's shown in the Magnum pic). Ivo tell me that the motor end
plate in the pic is only available on the lighter motors.

UHS (? I think that's their name) in Markham are working with Ivo to get an
approved mount for their spinners (which cover the whole hub and are large
enough to be significant on the O320 -- close to flywheel diameter.). They
are going to call me when they've worked it out, like REAL SOON NOW (but I'm
not holding my breath).

Tom

My friend Ron had his UHS spinner depart the aircraft in flight. Not trying
to be a wet blanket but be sure to check into this carefully. You should
talk to Ron Barber personally to get his detailed follow up but I don't
think it was positive but better check with him first to be sure.

Brian, Is Ron one of the ones that DIDN'T follow the instructions that are
supplied with every UHS spinner to loctite the spinner screws and let them
"cure" overnight and the MANDATORY use of a squash plate on top of the
spinner bulkhead to transfer the loads?? IF NOT, he is just tarnishing the
reputation of a perfectly good spinner OR did he actually have a "bad"
spinner that failed after being installed properly?!?!?.

I have been running a 10" UHS on the front of mine for 5 years. 4 1/2 with a
100 hp and now 25 with the 150H.P. with no problems. As far as I know, I am
also the only CANADIAN "advertiser" that markets Joe's spinners for him! And
no that doesn't give me a biased opinion. I have used all sorts of different
ones (and still do, to suit the application). UHS's are the simplest to
install however and pretty much maintenance free.

So far this week we shouldn't buy W.D. props because they are black, IVO
props because they throw blades and now UHS spinners because they depart
ship. Maybe we shouldn't buy Rebels either because they fly weird with the
push pull tubes hooked up backwards! WE are killing some small helpfull
little companies out there, with these "accusations", half truths, or rare
occurances and when they close up shop you guys won't like the price of
paying for certified stuff. Examples: $1000+ for a spinner, $3000
(wholesale) for a fixed pitch prop (retail about $4200), $6000 to $9000 U.S
for a composite engine cowling etc. etc. or are we willing to present all
the facts before making vague statements about product suitability??!!?!?

Sorry Brian (& ALL), I'm just tired from flying Young Eagles all Morning and
didn't really mean to pi__ in your corn flakes! We just need to watch how we
present info about questionable products, to be sure we give enough
information to support the statements, before we have no where left to buy
reasonably priced parts for our amateur built aircraft!

Hi Wayne

All I said was to check into it carefully. I did not state that the product
was bad but simply Ron had a bad experience but to check with him for
details i.e. was the product bad or his installation. I purposelly stated
it that way as I did not know the details nor would want to misrepresent
anyone. If you read it, you will see that I did not say the product was
bad.

I agree that there are often just opinions being stated & not necessarily
facts. This does a great disservice to people & noone would appreciate it
if they were on the receiving end. Opinions are simple but can hurt.
Fact/truth takes effort and we should all strive for this end.
