CG help please
 

I have a Global Waco bipe, the booklet has long been lost, this is the .30 size plane, I have a .30 FS installed.
I cannot determine CG point, wings are NOT swept, lower is back set approx 2.5" or so, cord is roughly 6" upper and lower wing.
Please advise as to CG point for this plane.

Thanx Bob

If the lower wing is the same span as the upper, then numerically, a point 2 3/4" back from the upper leading edge would be the 25% point for the pair. That's usually a safe starting point. Someone else here may know about your specific model. If the wings are not set at 0-0 incidence to each other that number will have to be adjusted.

I'd scale the CG from my SRE for you, but the lower wing is smaller.

Starting point is 1/4 the way horizontally back of the distance from the top wing leading edge to bottom wing trailing edge with the A/C in flying attitude. (25% MAC of this set up)
