Default tail trim

trex 450 se v2 jr770 gyro , dx6i rdio
my tail is mechanicaly centered, even travel both ways, blades straight, but in flight I have to add about 45 sub trim in the radio to keep tail from drifting to the right. i have about 63 gain set on the radio, any more and it wags. shouldn't the gyro adjust for the drift? or is it normal to add trim for the tail to adjust for rotor torque?

Sounds to me like it may be in Rate mode, not knowing much about your gyro I would look here first: http://www.helifreak.com/showthread.php?t=41692

i was wondering if that may be the case,, stupid question time, when in HH mode on the table and i move the tail, it will return to center,, and rate mode will move to one side and stay??

"When you move it to the side and it stays you are in HH mode, if it returns it is in rate mode.

Default RE: tail trim

that is what i just figured out, I have been flying in rate mode for over a year now, I have been pulling my hair out, wondering why the tail would never hold right.
thanks,
