I checked the plans tonight, the C.G. location is between 3-7/8 & 4-7/8 from the LEADING EDGE of the wing, not the wheel wells.

Control surface throws are spec'd as follows-

Ailerons - 7/8" up and 1/2" down
Elevator - 3/4" up/down
Rudder - 7/8" up/down

3/4 on the elevator doesn't sound like much, but it was way plenty in a tail heavy (I suspect) condition with mine. I just finished building the busted aileron back up, plan to sand and cover it tomorrow. She'll be ready for another go Saturday morning.
