Tail wagging only during inverted

[rkte]

Hi guys,

My Trex450 just got this problem recently
The setting are:
- GY401 w/ HS82MG
- TC: 98, 87, 80, 87, 98
- PC: 0, 25, 50, 75, 100

Belt, tail blades, and all rotor head ball link were replaced.
Also tried to adjust the gyro sensitivity.
Anyone got this problem before?
Appreciate for your advise and help.
Thank you.

Tail wagged onli in inverted but not in normal hovering? hmmm, that's weird

is ur servo rod flexing? also u may wanna go digital..

i do have some intermittent wag sometimes but not often

change rudder servo. confirm okay.

change rudder servo. confirm okay.

mine is already digital.. .07s/60deg, i run my gain v high at 95% for idle up. reducing it alittle to 93% does remove the occassional intermittent wag while inverted

My tail servo is very new.
Hhhmmm... will try UBEC 6V to make HS82MG move faster.

Oh, you also have the same problem huh....
Used to be intermittent wagging but now always...

try brining in the ball link in one hole , reduce the gain and bump up the HS and see what happens?

Just back from test flight w/ UBEC 6V.
No more tail wagging during inverted and the response from all cyclics are faster
Thanks.
