RE: Determining CG
Thanks for your suggestion. I was told early on with this airplane that the cg should be a little further aft than the instructions specified, so I made the cg as aft as possible. This airplane is now nearly balanced on the main gear. If I remove the propeller and spinner, the nose wheel will lift and the plane will drop the aft end to the ground. I too would like having to use as little down elevator as possible to maintain straight and level inverted flight. Just don't know how to get there with this model.
