I was considering building the slingshot out of pvc but lets just be honest here. I drive a Corvette. If i am able to fit myself and the rc aircraft in my car that in itself will be a small miracle. I sure wont be fitting a large pvc triangular structure in the car. So I am making some perches to affix the aircraft to my 1/10 scale redcat buggy and I am gonna drive the aircraft up to speed with the buggy, then hit the juice on the EDF and hopefully the aircraft will power into flight. Or that is the working idea, anyways. Brushless upgrade is on the way for the buggy.
