Hi Ron.

Any foamy that is 3D capable under 12oz can be use for this, 8oz or less and center wing is better. You need a Tx that as heli mode or is for heli. You need to beef up the firewall and the foam behind it all the way past the LE of the wing. this part has to be as rigid as posible. You need a sub-micro servo for the pitch with a torque of 17oz or more and of corse you need the motor with the VPP accesory. Any other question feel free to ask.
