go into the manual and use the trims there. You may want to use end points also.

If i may assume that you are using the Futaba 6ex equivalant, i might be able to tell you why.

The 4 "sub trims" are not really sub trims at all. They are basically extensions of the 4 trim buttons on the surface of the Tx. Where the trims on the surface move by steps of 4 (if im not wrong), the "sub trims" move these same trims by steps of 1.

The sub trim channel which trims the ailerons basically moves both the left and right cyclic servo at the same time. The only servo which will be able to trimmed on its own is the elevator servo. Best you can do is try to achieve the same angles on each servo arm and live with that.

Another solution is to get a servo horn that gets you the closest to center for a mechanical centering.

I believe only the Futaba 6EX has this limitation. Almost all other brands had trims for each individual channel.

Hope this helps.
