Clutch bearing & liner replacement

[zoombolt]

After a recent crash on my t600n I needed to replace the main bearings that were shot, along with a few other of the usual bits.

I then test flew the heli & felt that the clutch wasn't engaging quickly enough or as it did before.
I decided to change the clutch liner & then found that the large clutch bearing was rough, so changed that too, along with the smaller clutch bearings that actually seemed ok.

My question is, what sort of life expectancy do you expect your clutch liner & bearings to have under normal use. Mine lasted a year under learning/intermediate use.

after a ditch a while ago (when the bolt on the main gear snapped) it done my clutch bearing somehow, either that or i never noticed it was shot before, i just chck all bearing from now on, and my clutch liner was fine mate
