Glad that it worked out for you Jaba.
I went through the whole dynamic balancing rigmarole on my Continental. It didn't turn out well. Was on my 2 blade timber and fibreglass MT prop. Ran it up 2,000 on the ground and had it absolutely perfect on the dynamic balancer. Put it back together and take off.... nothing short of terrible. It was "thudding" on every RPM. Back to the drawing board and balancer back on. Got it to 2,200rpm static (we had noise issues at the LAME with the neighbours so couldn't go higher). Perfect again, until takeoff. The only thing that I could think was wrong was that one blade was dodgey and was bending forward more than the other in flight.
Arrived back home after LAME, prop damaged day after when aircraft was parked.
Fitted new Sensinich prop and new hub. Vibration no better. Swapped prop around 180, rotated prop two prop holes and she was as good as new.
It's a bit of a black art, no offence intended.
