Default Tail hunting on trex 600e, but seems to be power train

I have a stock trex 600e with 15t pinion and 35c 5000mah 6s packs, the problem is that when hovering the tail twitches or hunts, its not oscilating like then the gain is too high as have tried the gain right down and on the hole closest to the servo, plus i have tried with govener off and on but still the same problem

Anything i can try to test or things to check?

Cheers for any help

I have a similar issue with a Trex 500 ESP. It happens when I idle up, when the head speed increases. I'm down to replacing the main shaft to eliminate a bit of vibration. That could have a effect on the gyro. I have heard of static, main bearing wear, tail slippage as causes...

The main bearings are a minute bit notchy so might change them and put the third bearing block in as well

Found the problem, its the align esc throttle settings, if you have the esc set to 90% it is right on the piont of full power or a jump in power, its not linear, so if you get thus problem set your esc to anything above 92% or below 89% and it will be solved
