Have a Trex 500 ESP and enjoying it.

Have a bit of play in the tail rotor holders. I have already tried reassembling the trust bearing and tightening the socket screw but the play remains. I believe this may be causing a bit of vibration of the tail when flying. Was thinking of adding a washer. Anyone has any experience here?

The tail grip slop is normal. I really don't think it could cause vibration though. Check your tail blade balance.

Thanks for the feedback beeflyer2.

Do you think that the slop is there by design? What are your thoughts on trying to remove it by adding an extra washer when assembling the socket screw which holds the gripper against the trust bearing?

No, don't think it's designed slop. I believe you can eliminate it by carefully filing material from the ends of the hub, just under the screw heads.

or do what I did.....buy a kasama tail and never look back.

It's a complex, costly, glow powered anti-gravity machine!

Thanks beeflyer2. Filed some of the metal off the hub and the slop is definitely gone.
