Need C.O.G. info on Ultimate Bipe
I just installed the radio gear in a Goldberb Ultimate Biplane and need to know the center of gravity range in relation to the center of the lower wing leading edge, Right now it is at 3 and one quarter inches behind the leading edge of the lower wing in its centerpoint. Also, I need to know recommended throws on all the surfaces recommended for the first flight. Thanks Rick

Goldberg Ultimate C. G.
Ver batum from the manual.
To determine the Center of Gravity, measure back on the fuselage 2-3/8" from the leading edge of the bottom wing. The C.G. range for this aircraft is 1-7/8" ro 2-7/8". It is recommended that you balance this model upside down. Add weight if necessary to achieve the proper balance.
This is straight from the manual.
Here are the throws
Gentle
aileron 10º
elevator 12º
rudder 15º
Aerobatic
Aileron 12º
levator 14º
rudder 23º
