Holds KE fine at 3/4 to full throttle with little rudder deflection. Its when I slow it down and add more deflection that things get strange. Flew it again tonight...acts like when you apply rudder to pitch the nose up, the fuse has a reaction and wants to bounce back to level flight. I suppose it could be the very long tail moment, lots of fuselage side area behind the CG. This is only a 24% plane. Have a JR 8411, 155oz servo on kevlar pull-pull, no gyro.

Here's a picture of the fuselage, and the big rudder...is this considered a sharp trailing edge?
