Hello Guys:

I built a Mid Star 40. I put wheel pantson it. I also put a MVVS 40 with the tuned muffler( I didn't know any better at the time, MVVS's just came out when I bought it). I put only one servo in the wing. When I say this plane is hot I mean HOT! You have to hold opposite aileron when you break ground from the torque. I even have it on a Futaba super seven computer radio. I never saw or felt the need for 2 servo's. Nor did the 3 club hot sticks that had to have a go at it with the plane. Make sure all the control surfaces are tight with your linkages and fly the hell out of it.
