Does anyone else notice their passenger stick vibrating when in a steep climb at full power? It goes away when I lower the nose and/or reduce power. But it vibrates fwd/aft pretty intensely when I climb out at Vx. I can feel it a little in the pilot side and if I grab the stick it of course stops. I'm sure if I flew right seat the pilot side would do the same. Is the long arm just exaggerating the prop vibrations?
