Hi pilots, I was hovering about 4 feet high & suddenly the tail seems to lost control & starting to spin. I landed the heli with no damage & I see the tail servo is glitching forward & backward a bit & making gee gee gee noise, stick movement is not proportional to servo travel movement. I unplug the battery & retry, everything seems fine. Going on the 3rd pack, suddenly happen again. The light on the Rx is solid, power on the Tx is enough, just dont know why the servo will intermittenly glitching. Any idea out there ?????

Possibly stripped gears, bad connector pin or bad servo wire connection to the circuit board.

Plug the servo into the rudder channel and see if it stays steady.
What is the led on the gyro doing when this happens?

I just fixed my that was acting tail funny, and my tail bearing where, well, destroyed, put new ones,works like a charm again, you might want to double check those.

If the tail blade orientation mechanism is not smooth, then is is a battle servo against mechanic

after I unplug the battery & repower everything, the tail servo act like normal, solid movement, I dont think the gears are strip coz it is only doing very once in a while. I bundled the xtra servo wiring & stuck it together with the gyro & the other wiring from the ESC, also very close to the Rx, would any chance be electronic interference ?
Thanks !
