The ideal C.G. position is 140mm (5.51 in) behind the leading edge measured at
where the wing meets the fuselage. In order to obtain the C.G. specified, add
weight to the fuselage or move the battery position. Check the C.G. before flying.
If you are converting this model to electric, please move the C.G. forward 10% of
current C.G. distance from leading edge to compensate for weight of fuel.
Measure C.G.with the wheels in retracted position
