Tracking issue, bad blades or dampers?
Hi!
During last flights I have seen that the blades get out of track at headspeeds above 2000RPM on my Airskipper 50. Tracking appear ok at lower headspeed. Checked with pich angle indicator, and found that angle of attack is the same on both blades.

It was not like this before. So, can this be that the blades are getting "old", since it has been 8 veeks since last session at the field? can it be bad dampers?

Probably its the dampers. I don't remember the part number but harder and more durable ones available at JR.

Also read the threads below ;

Another problem can be the loose ball link on the blade holder arm. It maybe become helpful checking it.

thanks for good input, I'll replace the dampers. Just have to find a good dealer for those hard K&S dampers!
