Got a ? for you folks. I have a Great Planes CAP232 .40 with a OS .46 FX. My problem with it is when running straight and level and pull the elevator a little to much it goes into a violent snap roll. I have checked everything I can think of and cant figure it out. Both elevator halves are even and travel even up and down. The only way to get it to stop was use LOWER than recommended low rates and run a 11x4 prop to slow it down on top end. Is this normal or is something out of kilter? Thanks in Advance. Blacksheep
