Henseleit 3DNT - Rocket - 3DMP > Blade Tracking and Vibration

Been chasing a little problem for a few days now , I have developed a vibration in the skids and vertical on the tail fins.

I re looked at the tracking of the blades and both look ok in flight , but installed the lock and set them both at 0 , one was at 2 degrees .
I believe this is done from the front of the machine as stated in the manual and not the sides , as I get different readings.
This means that now , the rod 625 is 95mm and 92mm , does this sound right ?, as I still have the vibration .
Funny thing is , is that if i put them both equal at 95.5mm , the tracking looks out when in flight , but i dont get the vibes......
I have also tried the pulling of the tail belt.

Cheers

i had a similar problem, it turned out to be the blade grip bearings were worn, dont know if thats exactly what it was but, i took the head apart replaced the bearings -orings etc etc.. the orings had dried out so it could have heen that as well. but problem fixed . this thing is really fun at 2100, i only do it once in a while but it makes people look when it goes by!!!!! I cant wait to buy another (classic) that is...

just went flyin after about 8 months of nothing but work
its great to not have a job !!!!!!!
