GY401 tail kicks out

[LipolyGone]

Hi guys I've put the new motor & speed controller from the Trex 450 se v2 from align into my Thunder Tiger Mini Titan but since doing so the tail kicks out in high power climb outs. Has anyone else noticed this with there tex 450 se v2's? Im running a gy401 & my tail servo is only an hs65 mg but with the old 430l it was very much more controlled.
It is almost uncontrollable now & i fear ive turned my sweet Mini Titan into a monster.

you might have to adjust your gain, that 430L motor didn't have the torque that this new one has, so having it set up to suit that the motor and then chucking in a more torque motor the gyro will not compensate for this torque. so just reset the whole gyro and you might find you need to up the gain

Thanks NightStalker I will give it a go tommorow.
Another thing I've noticed about the mini titan is the motor plate doesnt have many if any cooling holes in it having looked closely at the new 430LX motor it is designed to pull air through it & exhaust it at the top side & end of the can this motor plate wont allow this to do this hence why people on here are claiming their mini titan motors are getting hot.
I'm going to rework my motor mount a little to see if I can get the motor temps down a bit.
