Design parameters for a .010 powered profile stunter
« on: December 14, 2011, 06:28:21 AM »
Hi All,

As the title says, a .010 powered profile stunter.  I am thinking along the lines of the Goldberg Goodyear profiles suitably reduced in size.  I believe the profile fuselage will be a bit better for handling instead of a full fuselage ship.  Others are under speculation, but I need to know some some parameters, target weight, etc.  Might be a case of some of that super expensive 3 lb wood from Campbells! LOL!!

Thanks

I would hazard a guess that about 80 sq. in. and 3 ounce weight would be good.  I had a 1/2A Snapper at 4 ounces and 105 sq.in. with the .020 and it was indeed "snappy".  Look up Randy Heydon's Lil Bit, as it was competition capable.
Think S.M.A.L.L. y'all and, it's all good, CL, FF and RC!

I built a profile with, probably, a 12 x 3, 1/8 sheet wing.  I made the bellcrank out of a plastic picnic knife. I flew it on thread lines, about 12 ft.  It would loop and do figure 8's. I later put a PeeWee 020 on it and flew on a little longer lines.

  I would guess that you probably don't need to bother with a prop, or actually starting the engine. These teeny-weenies are easy to just whip up to speed.

But .010's serve a purpose!  Mosquitos are attracted to the sound and stick to the oil! (REALLY!!!) They provide a vital service to mankind!  And to think of the millions of $ that have been spent on mosquito eradication research when such a simple solution is available!   %^@

Here is a Micro Ringmaster Stunter for the Cox .010 engine. It has a built-up wing with a 17 1/4" wingspan and 53.5 square inches of wing area. That is 56% of the wing area of a Baby Ringmaster. It is not Larry's recommended 80 square inches, but I think the size and wing area are OK. My Micro Ringmaster is a 1/4 scale Ringmaster with a slab wing. It has 23.8 square inches of wing area. it will not really stunt, it is more of a rocket than a stunt airplane. Let me know what you think.
Thanks, Pat

Looks like fun to me!  ;D  I hope someone builds one and lets us know how it goes!  It certainly will fly!

Brother Pat!

That makes me want to consider a Micro Super Ringmaster Stunter! ;D

(a Micro Ringmaster Imperial Stunter would be the bomb! )
