RE: .15 size pylon planes
 
If I remember correctly, the Heinkel was an upright engine, made for easy starting. The Polekitty was side mounted, and the Folkerts was inverted (I've been told, never had one) and you had to stand it on a wingtip to avoid flooding it when starting.

I'm pretty sure they're all glass and foam kits. I've built Gager's P39, and Gall's Stinger (similar to the polekitty, midwing at least), and an Estralitta from back then, don't remember too many during my venture into QM15 that were built up. By the time I started, almost everything was glass & foam.

I found some plans and ordered them, shoestring, el bandito and deja vu. Finding a strong running .15 will be another issue.

AMA also has one called "quarter midget".

the kits are fiberglass and foam. you add the wood and finish

RE: .15 size pylon planes
 
the Folkerts is a inverted mount. the best way to start them was to roll the plane over and start the engine in the upright position. I flew the Blouch P51 near the end and that plane was all balsa and foam construction. you had the others correct . I will try to put some pictures up as I have a few planes on the wall

RE: .15 size pylon planes
 
What size props were typically used on these planes?
The rules no longer appear on the AMA site, does anyone have a copy they could post?

RE: .15 size pylon planes
 
don't take this as gospel, but we used to take Rev-up 7-5N (narrow) and they'd end up about 6 1/2" diameter or so - or you could go with a little more blade area, take the top flight super maple 7-4 1/2, trim them down, narrow the blade a little bit, thin 'em out, etc.

Towards the latter part of the racing, the props were molded continuous strand carbon fiber, about the same size, but they could be a little thinner because they were stiffer and stronger.

Somewhere I still have a prop or two.. not many, but I think I do.

RE: .15 size pylon planes
 
Painless - I need to correct some info on the props. I dug up one of my old carbon fiber props from "back then" and found that it was just a touch under 6" diameter, not 6 1/2. It measured 5 7/8, but the RPM marked on the back was a little high compared to what I liked to run - it's marked 28,100 and I used to look for props that would load the engine (nelson 15) to about 27,000 - 27,500 on the ground (peak).

That El Bandito is a neat looking airplane. Some day I ought to build one of those.

Thanks for the prop info. My plans from RCM arrived a few days ago, time to plot some foils and start burning foam.

If you need a very good QM 15 engine let me know.

What will you take for all three kits?

What kits do you have?

RE: .15 size pylon planes
 
Two of the kits are now in Kansas... :) I bought the polekitty and the folkerts, I think they're gonna be fun! I still have a Gager P39 that needs some minor repairs, and a Gall Stinger that would be flyable with a radio installed again.

Hey there Conquest 15. I have a Gager Heinkle kit if you or someone else is interested.....

epr3 08-15-2009 05:11 PM

RE: .15 size pylon planes
 
On a side note while looking for the QM15 kits I came across 2 Scat Cat kits both NIB .....one is a prebuilt kit and the other in a regular kit

I really need to get one of those Rivets kits someday.[8D]

And I have 2 nelsons and 2 Ron Young Coxs with ABC, and parts for sale too.

Kevin, are you trying to tempt me into getting an airframe engine combo???:)

Hi Kevin, What do you have in engines and parts?

RE: .15 size pylon planes
 
The P39/P63 won a lot of races. I manufactured over 200 kits. The full scale P39 was the Aircobra. The P63
was the Kingcobra. There were a few tail dragger versions built for carrier trials, but did not win a contract.
That version was called the Airabonita. Several people built a Quarter Midget version of the Airabonita,
including Denny Sumner. Sumner won the Silver Cup Race (if memory serves me correctly) 4 times, and
placed second once with a tail dragger. That model used to be on display at the AMA Museum, and I believe it still is there. After WW II Bell Aircraft actually built a "V" Tail version of the Kingcobra for test purposes.
Currently I can supply a semi kit which includes full size plans with all templates, and a fiberglass fuselage.
I won't get back into cutting foam cores for one kit. Price will probably be less than $75.00.
It is not in my nature to take full credit for this model. I had owned and raced the Bob Root version
"Lil-Cobra". When it was no longer available, I decided to make/build my own, so I started with Root's
design, and modified it to my liking. The design went through three iterations before I was satisfied.
Recently I have thought about building one as a scale subject, possibly even electric.
If anyone is interested I'm still in the phone book, or you could PM me.

If you have an old kit bring it to the Jullian race next week. I might be interested.

I still have a House of Balsa Shoestring kit and two HOB wing kits.

Fred Reese and others used to publish plans of other Goodyear Midget Racers that used the HOB wings which were built on arrow shafts.

Also have a couple of Dave Latsha Rivets fuselages and foam wing cores and a D.H. Racer designed by Jimmy Katz from N.C. with Fiberglass fuselage and foam wing core.

RE: .15 size pylon planes
 
I can't make it to the Julian Race. I have another comitment. However it's possible Mike Langlois still has one of my kits. Check with Mike. I'm sure if he still has one he would show it to you, and possibly even sell it to you?

RE: .15 size pylon planes
 
Dan,
Just a small correction. The DeHavilan Tiger Moth 1/4 midget came from Jim Katz, not Jim Nix?
Katz and Mike Langlois are putting on the race next weekend (10-24/25-09) in Julian NC. Greg
