Title: .010 stunter how much wing area?
Post by: dave siegler on February 26, 2018, 04:24:33 AM

Going to put together a simple airplane for a cox .010.

We do a lot of demos and this would be a hit. 

Just to fly maybe a loop and 8's

thinking 80  100 square inches wing a sheet of blue core foam about  12 inch span with a small carbon rod. 

Lines 10 feet?   I could almost self launch it.

Any reference designs?

what kind of structure are you planning? The plane should weigh under 3oz. The engine with original prop produces 5 oz. of static thrust.

I would aim for 100 sq.in. with a built up structure. 15% thick airfoil.

Research Randy Heydon’s Lil’ Bit. It would do the whole pattern. I think it was published in Model Builder. He did use a bladder to assure consistent power.

Hi Dave, in the very early 1960's my ex-wife built a Midwest Sniffer(FF) and powered it with a TD .010.

the model has 139 sq"s and weighed about 3.5 ozs. and it climbed straight up(spiral) like a Zipper.

That was in Albuquerque,  the flying field was close to 6,00 feet.

I recommend you go to the trouble of using a built up design like the Mini Zilch or better yet, a

Southwest 1/2A Snapper.  Use 25-30 foot lines(.008"-.012" stranded cable). A 1/2oz tank or better

yet an appropriate sized balloon will do the trick. Best of luck.   For Historical(Hysterical..) reference;

Bare built a 160 sq" scaled down PDQ Lion Tamer powered with a PAW .5cc diesel; and it literally

screwed him into the ground using 35' X .012" lines.    I wish you the best of luck with whatever

you end up building and flying.

Tony G...Yes, it's me, back again after mucho health BS.

Another data point:  Frank Warburton's Mite was Cox .010-powered, span 13", 36 sq. inch area and weighed 1.75 oz.  "Does most stunts."  (ref. American Modeler, Feb. 1963)

Tom Lay also build one--perhaps a scaled down McDonald Stiletto?

My Micro Ringmaster Stunter has a 17 1/4" wingspan and 53 1/2 square inches. A Baby ringmaster has 95 square inches of wing area. That is too much for a Tee Dee .010.

Hi Dave,

I have the plans for Lil’ Bit. PM me your address and I’ll see if I can dig it up and get it in the mail for you.
