450 450X slow tail wag with replaced stockT- servo using Align DS425M

again cheers to the people who helped me w/ the setup of the new Align servo on my 450X. to most, experienced anyway, it's simple. to me it was like a mystery that I couldn't not be sure of solving, unless I was willing to risk another crash.

what I have now is the DX6i gyro dialed in @ about 63%, which seems 'tight' & precise. but there's is a constant, slow tail wag/ woblble which I cannot track to any particular obvious cause, except maybe a bind with the pushrod extending from the new T- servo to the tail case. The eflite ball linkage which attached to a circular servo arm on the stock T- servo would not fit the new Align DS524M, so attaching the stock ball link to the 'star' shaped Align servo arm is a much tighter fit, & there's absolutely no 'play' between the rod's connection to that ball link. I wonder if that is causing a bind, & therefore the wag. Physically that's the only thing I see as a possible cause

Electronically I was advised to adjust Dial 3 on the AR7200BX, but all that did was make the wag slightly more pronounced, or slightly less

A friend who has no real operative knowledge of r/c helicopters but is a vehicle mechanic suggested gamely that because the Align servo is of higher quality, & on a different frequency, that perhaps the wag is caused by the new servo 'overpowering' the swash servos. So in that case there would have to be adjustments to compensate for that-- would be the educated guess from there

I'm really pleased to have the heli up & flying again & I feel like the new T- servo has more authority too, which I like. But obviously a wag is a malfunction, & the sooner I render it gone, the happier & more confident I'll feel flying, slashing & burning like the advanced/ intermediate pilot I am :D

Probably this weekend I'll post a video of the 450X on youtube; my channel is: render767

seeing the wag on video I'm sure will key somebody into what's wrong, & maybe lead me to the solution that way as opposed to simply describing it here
