biggest problems with that plane was that it is short coupled, not a problem with proper balance and throttle control on takeoff. Biggest problem is that like all Great Planes kit it's a porker. It really should be about a pound lighter. The wing loading gets high really quickly on this plane. If you master the takeoff the plane flies great, But be warned if you try to force this plane off the ground before it's ready to fly it will snap and bite you on it's way down.
