The other ones. I would just like to purchase the threaded rod that they use so I can cut it to length and reinstall.

The tail motor is a PITA, I had just got my bird flying well outside and the tail wont hold anymore. I had to trim full right and adjust the pot before I realized the motor just isn't putting out as much thrust as before, this is after about 25 flights but I do have the gyro cranked right up.

I do love to tinker with this heli and I think that is half the fun for me.
