Shake in stick when climbing

[JoeRuscito]

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?

Joe, I about aborted on my maiden because of this! It’s the prop wash hitting the horizontal stab and elevator.

Based on experiences in other aircraft types I'm with Shadowrider and it either gets worse or is more noticeable the further aft your CG is.

Some times when the trim is not well situated I have felt the shake.... once I corrected it , it normalizes

I've got a 74" Sensenich on my IO-240B, and I get stick vibration/shake from the elevator on full power
takeoffs, it goes away as soon as I lift the tail or get airborne. It's just pulsing air hitting the tail as
far as I can tell. A bit unnerving at first, but I'm used to it now.

Sounds like this is pretty common. I had a passenger the other day point out how extreme it looked on climb out. I had noticed it before but really wasn't concerned but figured I might as well ask the group. Mine usually persists until I reduce my climb angle or decease power. Thanks all
