EQ3D and Expo acting like Sub trim?

Just got off the phone with Bob over at Quest (Smartfly). The guy was awesome and explained what I was doing wrong with an issue I was having, and squared it away for me. I dont want to bother him again over somthing that I am sure I am doing wrong, so i figured I would reach out to the forum first.

The other issue I ran into is this:

When dialing in Expo, the control surface moves as if I am putting in subtrim. This is on a dual servo aileron setup.

JR x9303
921 Receiver
Futaba 9155 Servos

Example:

Subtrims are set at 0
All trim's are 0'ed
All three flight modes are set to 100% throw and linear on all surfaces. ( I have set my throws yet)
I havent tried other surfaces except right wing.

When I dial in +50% on the right wing to numb the stick the Aileron will drop and continue to drop until I stop rolling the roller on the TX. As an FYI, it does numb the stick.

When I dial in -50% on the wing to make the stick more positive the aileron will go up until I stop rolling the roller on the TX. FYI, it does make the stick more positive.

On both + and - expo both servos are moving, its not that one is moving and the other is binding up.

Any thoughts?

Thanks guys!

Trying to mess with this for a few and also noticed that it happens when I adjust the throws to diffrent %'s. If I roll the roller when adjusting throw on any of the three flight modes, the servos will move.

Please disregard. I beleive it is within the radio. When I take the EQ out of the loop it still does it.
