.15 size pylon planes
 
Call me weird but I have this burning desire to build a .15 size pylon racer from back in the day. I have looked around but but can't find anything from back in the 70's or 80's as far as old kits, not even sure what was available back then. Does anyone have any info on what was winning back then and the hot set ups? I would be interested in buying old plans or even kits if someone wants to part with them. I have the capability to plot airfoils and cut foam wings so building from scratch is not a problem. I have also raced Q500 for a few years so the speed and piloting skill is not an issue. One other question, where is a good place to buy balsa since Lone Star burned down? When I do a search on quarter midget all I get is the new QM 40 stuff.
Thanks in advance.

That's cool, I though I read they were not going to reopen. Now if they only started selling the Scat cat again.......

Matney models has some .15 size kits like a nifty looking Rivets.
If you ask nicely BobHH may be able to hook you up with a Scat Cat.;)

RE: .15 size pylon planes
 
I learned to fly in 1988 on a sig kadet mk IV, my 2nd, 3rd, 4th etc plane was a scat cat, it was a steep learning curve. I actually made some aluminum templates for the fuselage and tail feathers for the SC. Made some airfoil templates too. About that time lone star burned and also had a hard time finding 2" foam for wings.

I have seen the matney models, not a big fan of the rivets. I like the Sig Doubler II style. If I could get some names of planes I could search AMA, MAN or FM plans for such.

You could probably get Greg Doe in Smyrna TN to make you a kit for a P39, I am sure he still has
his molds. He is in the phone book.

RE: .15 size pylon planes
 
I had one 15 sized (sorta) Q500 kit cut a couple years ago, I don't have any more now or probably in the near future so I'm sorry, but can't help you.

There has got to be a few QM 15 kits still floating around, it was a pretty popular event.

Duane Gall has my QM 15 Estralita (Gager) kit and is making molds off the fuse. He should be pretty close to having it finished. This is a sweet looking little plane. I'll check with him if you'd like to see if he'd be willing to sell a fuse that you could cut a foam wing for?

PAINLESS 07-12-2009 10:42 AM

RE: .15 size pylon planes
 
Thanks for the offer, do you have any pics of the plane you could post.
I'm waiting for some info on a Prather Little Toni kit from another member here.
Do you know the names of any other planes? The AMA has a very extensive plan collection but it is not searchable
and if you don't know what your looking for it's all most impossible to find a certian type of plane.

RE: .15 size pylon planes
 
Try House of Balsa as MFG and the kits were, Shoestring and Miss Dara. There was a Stafford kit of a Mustang. Others included Ricky Rat, Miss San Bernadino, El Bandito, Miss Paranoia, Pole Cat, Heinkel, Estralita, Shark, Napier, Folkerts , and so on. Plans wise, Fred Reese, had many that he did and released with the magazines as plans in Model Builder and Model Aviation.

Hope this helps for names.

Thanks for all those names.
What were some of the engines being used in the planes? I know of the Cox Conquest .15.

fizzwater2 07-12-2009 12:05 PM

RE: .15 size pylon planes
 
at various times: Supertigre G15, Rossi 15, Conquest 15, Ron Young conquest 15 (abc piston/sleeve setup), Taipan 15, K&B rear intake/side exhaust 15, and finally the Nelson 15, two versions - 12mm crank diameter, 15mm crank diameter.

There are probably others - but those are the ones I have in my "collection".

PAINLESS 07-12-2009 03:32 PM

RE: .15 size pylon planes
 
More questions.
What size prop was used?
Was nitro content limited to anything?
Did the rules require the planes to be a copy of a full scale plane? Seems they were.

fizzwater2 07-12-2009 04:24 PM

RE: .15 size pylon planes
 
If I remember the rules correctly, they had to be "recognizable replicas of full size planes that have either raced or were designed to race (or speed record attempts)".

RE: .15 size pylon planes
 
I had a Spirit of St. Louis QM that had the K&B .15 QM motor in it. ( do know how it got approved legal but it did) If I remember we were limited to 15% nitro in the fuel but don't quote me on that. It was a truck and a friend of mine T boned me between pylons 2 & 3 with his P-51 glass fuselage QM. This was in Hawaii and the wind blew all the time and they were really to small for that kind of weather.

fizzwater2 07-12-2009 07:41 PM

RE: .15 size pylon planes
 
Yep, 15% fuel, supplied by the race organizers typically, like current Q500 and Q40 races.

Mini-pipes on the engines, no mufflers. Noisy little buggers.. but it was way cool listening to the N15's on the race course!

I have a few .15 kits if there is anyone that is interested in them. I would like to find a home for them. I will try to see just what I have

Epr3,
let me know what you have, post pics if you can.
Thanks

I spoke to my friend, he can do a fiberglass fuse of a Mustang and a Stinger, he may be able to cut cores if your interested also. Just let me know.

fizzwater2 07-13-2009 03:16 PM

RE: .15 size pylon planes
 
EPR3 - what maker (brand) of kits are they? Do you have any pics at all?

PAINLESS 07-13-2009 04:44 PM

Daven,
Any idea what your friend would want for a fuselage?

epr3 07-13-2009 05:04 PM

RE: .15 size pylon planes
 
the Folkerts was by Jim Deyoung, the Polekitty was by Gail Jacobson, and the Heinkel was by jim Gager. they were all top competitors in their day

BarryReade 07-13-2009 05:38 PM

RE: .15 size pylon planes
 
Are they all balsa, balsa and foam, fiberglass and foam???

fizzwater2 07-13-2009 05:48 PM

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.


PAINLESS 07-14-2009 02:58 PM

RE: .15 size pylon planes
 
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".

epr3 07-14-2009 07:50 PM

RE: .15 size pylon planes
 
the kits are fiberglass and foam. you add the wood and finish

epr3 07-14-2009 07:54 PM

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

PAINLESS 07-15-2009 10:01 PM

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?

fizzwater2 07-15-2009 11:21 PM

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.


fizzwater2 07-21-2009 03:10 PM

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.

PAINLESS 07-25-2009 07:35 PM

RE: .15 size pylon planes
 
Thanks for the prop info. My plans from RCM arrived a few days ago, time to plot some foils and start burning foam.

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.....

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
