In addition to my HH issues after my last crash, I had another problem.

While in a hover, the rotor belt moved and was riding on the edge of the tail rotor pinion. Didnt crash, but was lucky to get it down in one piece.

This is a brand new tail boom, never crashed, and a brand new tail assembly. Does this happen because the boom is slightly bent and I cant see it, or because my belt was too loose? Do I need to tune something, if so how?

Thanks!

Ever notice how crash rhymes with cash?

rotor belt problem

Sounds like your belt is to loose.
Review the instructions. The belt tensoin should be so that when you
press on the belt at the autorotation penion it should deflect about
1/2 to 3/4 of the hole belt space.
Also the idler bearing at the tail should aid in keeping the belt on the penion at the tail. Although I have heard that some folks remove this idler bearing. I don't see the logic in this so I haven't done it.
Hope this is of some small help.
Regards
