Cheap foamboard RC delta

[Sixties Sam]

I just built this little RC delta from two sheets of 3/16" thick foamboard from Dollar Tree ($1.00 per 20"x30" sheet) held together with hot glue. I patterned it after one I saw on flitetest.com. It has double thickness on the front 40% of the wing, forming a Kline-Fogelman stepped airfoil of sorts. It uses a motor, speed control, radio, and other stuff I had laying around. It weighs about 10 ounces, and spans 28". It uses elevon control, where the control surfaces on the trailing edge of the wing can move in opposite directions for ailerons, or together for elevators. It should be fast and fun, and my investment was all of $2.00!

I hope it flies as good as it looks.

Very nice Sam, that plane looks like a lot of fun.

You may have seen these before - when I lived in Southern Nevada several of us built these and would "dogfight" with them.

Building these was the only time I looked forward to seeing election posters

Yes, Sean, I've seen planes made from coroplast posters. That's another good way to make cheap, simple planes to just have fun with, and not worry about ruining a high investment plane!
