Default Brute force prop Racer

I got out to the field early Sun., and there was this 3 man
Team running this big race plane. I don't know much about it....but they said it was a "Kelley Racer"....

....they were flying it....and doing some tuning....and were
heading someplace in the Midwest....where 4 times a year,
men like these gather and race these "Beasts"....

Default The guy with the neck strap....

....was the owner/pilot....and the big guy was the tuner.
I was busy settin' up shop....and had a new plane to
maiden....and didn't get to talk to the fellas much....

....but I did get these pictures to share....they we're
kinda busy too....

I don't know what class this thing runs in....what size
or Brand the motor is....what prop, fuel, or anything....

....but I know that it was loud and fast.....they said it
would go 170.....and I think they said it weighed about
30 lbs, or so....

Default The engine was a thing of beauty....

....as you can see....an opposed twin cyl. 2-stroke....
with a big pumper carb, and a split manifold. The heads were "special made"....high compression jobbers....

....converted back to "glow", so I assume they were running
methanol, nitro, and oil. I don't know what the displacement
was....or how high it turned....

That pick-up on the front of the crank....was not for ignition,
timing, or advance....(obviously)....so it might have had
some kind of an rpm data recorder.....(just a guess)

....see the exhaust headers under the cyls....

Default Brute force prop Racer

....they formed together in a collector....just a "dump"
exhaust....with no pipe, or silencer at all....

See those 3 sets of ear-muffs hanging on the stand in
post #2....? They're not hanging there to hold the stand
down....trust me....that was the loudest model plane
I've ever heard in my life.....I held my hands over my ears
when he ran it up.... ....I was standing behind it.

Default Brute force prop Racer

That is one sweet looking plane and engine.

I can't imagine running glow in something like that, but I guess if you have to ask how many oz's they burn up per flight, you probably can't afford it.

I'm not aware of a class like this that races in the Midwest, but would love to see some of those on the race course.

Default F1D Kelly

Flyboy Dave, Daven, and Chuck Auger,

That would be a Kelly for sure. Those planes are used for giant scale racing. There is formula 1, t-6, unlimited, and others.

The Kelly is for formula 1, which has to be a 42% scale model and a 6.0 cu. engine (I think)

They race somewhere in: Ohio, Kansas, Texas, and Arizona.

I have a qm-40 Kelly that looks kinda similar. I think it is a Lyle Larsen aircraft. Old school with the larger fuse.

VERY cool stuff and very fast, noisy, etc.

The motor size is 80cc, which is about 4.70ci. I don't know how many ounces of fuel they run a flight, but we go through around 50 per flight, which is just about 4 minutes. At about 50% nitro it does get kinda expensive.

They are actually racing as I type this in El Dorado, Kansas. For more info on the races, go to... http://www.usrainfo.org/

Here is an article on the types of motors: http://www.luvaraairracing.com/artic...ow/aerrow.html

Or go to the gallery and see more Kelley's etc.. http://<a href="http://www.luvaraair...acing.com/</a>
