Found an Easter Egg that is about 4 inches tall and 3 inches at widest point.
Was a candy container and pops apart just like the little easter eggs. There is a small molding area at the base that is the same size as a BT-50 tube. So getting a tube into the egg shouldn't be difficult.
Would it fly fine with long trailing fins and motor and the rest of the gear up in the egg? I know balance and stability would have to be worked out.
Or maybe keep it super simple and have motor eject and tumble recovery?
Dang now I can't walk through a store without thinking 'wonder how that would fly?'
