It sounds like you reduced your throws to reduce snapping. Even after 20 years of flying, I ran into a similar situation lately. I never got around to lateral balancing my latest aircraft. Even with a foreward CG, it still snapped on full low-rate elevator. After Lateral Balancing, I was able to move my CG back another 3/4" with good results and no snapping tendencies.

i have the plane lateral balance i am trying to move c g back it is flying good but just slugish now is that becuase of the forword c g
