- Check to see that the tail rotor blades are set close to “neutral” once you have the above steps taken care of. With the rudder stick centered and trim set to center, the square base of the blade roots should be flat and lined up with each other. This will get you very close to where you need to be, but some trim adjustments will always be necessary later.
I came across this problem recently when replacing the TR shaft:
The manual gives detailed instructions on TR assembly, but as far as I recall, there is one thing that is not mentioned: When you insert the pushrod through the TR shaft, it does not say how far you should push it through before fixing it with a setscrew through the eyelet. Maybe the pushrod is inserted too far or not far enough?
