Another UCD3D engine question
I would use the 91Fx and then build or buy me a moosecan for it.
I have a ST90 on mine. I am in the process of building me a moosecan for it.
Keith wilson from wilson hobbies in Kennett, MO (elvis on RCU) has a 91Fx w/ 14x6zinger and a moosecan on his UCD. And it will rocket out of a hover. He also sells the moosecan and headers for the 91FX. Then all you have to do is bolt it on and go fly.
