A109SP T/R
Good morning Blender,
Can you please give me more info on the DA are you operating?
Did you operate on the same conditions with a S model??
Basically the S and SP has the same T/R.
There is no way for the A/P to affect your mechanical control into the T/R, so for me sounds like a Rigging problem, only if you are into the graphs.
Best Regards to all
