Tram,

The Goldberg kit is a really good plane. If you have a place to fly a larger plane and can transport it I say go for the GP Chipmunk.
Capt G what do you think?

With the 155 and a 17X6 prop it will take off in about 50 feet. I imagine the plane must have goobs of power with the YS 140. I'm going for a more powerful rudder servo. I have a 6635 Hitec installed but I'll be replacing it with a higher torque Karbonite.
