I have a Giant Scale Planes 65" Sukoi ARF. It has a bad tendency to drop the right wing whenever I do a positive G manuever. It will track right when going through a loop, it will drop the right wing if too much elevator is applied and it tends to fly tail down and drop like a brick when power is reduced. It is balanced wing tip to tip, so I do not have a heavy wing.
I'm trying to determine if this could be the result of the aircraft being tail heavy or nose heavy. I've check both elevator halves and there is no differential in their throw. I've looked carefully at the wing and cannot see a warp. Wing and stab are parallel.

I'm ready to tie a wrench to the nose and go take off. If it's worse than I'm nose heavy, if its better, than I'm tail heavy. Then I can make the corrections, if I can get it back on the ground in one piece!
