Need help with tail kick problem

[AlastairC]

Been trying to sort the tail kick round on my 450 for a while now. Had the tail apart many times and it seems to be smooth and bind free. If I put the tail gyro gain any higher I get tail wag. The only suspect I can think of is the gain in the esc governor. I have as CC ICE 50 with the gain set at 15. The log is as follows:

Also a video of the flight

Garden Flying - YouTube (The log is from about 1:38 in the video)

From what I can hear and see it sounds like the governor is way over compensating. The gain was set at the lowest standard setting. Should I drop this down lower? Help! :-)

Thanks,
Alastair

15 should be good for the governor, works well on my 250-700's.

Align's are notorious for tail wags caused by slop in the tail.

Align have copied KDE and have produce the tail upgrade to their 450-700 heli's.

I would recommend installing this upgrade with a carbon push rod.

Thanks... I will do the upgrade when i can find the 450 one in a shop. The thing is that the tail holds well and does not wag. Just goes right if I punch the collective hard. The motor does sound like the rpm's are overshooting in the climb and not at end so that is why I thought the gain is too high.

Upgrade done with V2 tail box and new slider (kept the stock push rod) and the tail is now totally locked in even with the 3GX on a full power climb. Really happy now!
