RE: Great Planes 25% Yak 81" 12-lb, seen on Fly3D Magazine
As I said, I have the fuji 50 in mine with the reveiver and batteries in the aft mount. one rudder servo and two elevator servos in the tail. my cg is at or just behind the aft location. It flies great but I will be moving it even further aft to help in the 3d and get my trims closer, it has a little pull to the canapy still. The recomended cg seems to be very conservative, don't be afraid to play with it.
