RE: Autorotation tail drive kit?
I installed the auto rotation tail drive o-ring kit. I must say that it does seem to help keep the heli pointed straight ahead when you go into throttle hold. Before the kit was installed I noted a slight twist to the right as the power came off. Seems a bit less pronounced now and I was able to use some tail input during the auto phase before touch down. I have to play with it more but my autos from around 6 to 7 feet were nicely controlled and on heading!!!! Its a confidence booster because all my landings on Sunday were autos from 4 to 6 feet.
I noted that the kit came with 3 washers to set up the tension on the O-ring. I put two washers in and it just started to turn the tail rotor with lots of slippage. I then put all three washers in and it seemed to be a bit too tight, although it really drove the tail rotor well. I figured I would lose too much rotor speed like that so I removed one thin washer. Thats worked well so far.
