Hatz Biplane Association

I have finally received my Rotec radial engine for the Kelly. I am studying some preliminary CG questions -- mainly in reference to installation of the
engine, but have hit a roadblock. The plans that Dudley Kelly put out do not have the forward and aft CG limits shown. Does anyone have that information?
These limits are pretty critical in reference to all of the modifications that are being done on the Kelly. I'd appreciate any comments/input in reference
to the location of these limits.

Thanks, Stan

Doing more research on the CG limits, I came across this information:

I think this will do what I need to accomplish. I would still take any comments on the limits.

Thanks again,
Stan
