3Gx Swashplate level and Subtrim

[stargazer]

I have been trying to do the mechanical setup of my Trex-550dfc in the DIR mode,I am using the Align alloy servo horns and to get the servo horns central and the swash level with a swash leveling tool,I end up with subtrim of about 30 on each servo.I have tryed swaping the servo horns between different servos but they seem to sit the same whatever servo they are on,I also tryed the plastic horns which came with the kit but these were worse.I know little to no subtrim is good so do I buy more alloy servo horns hopeing they will be right,I mean it could get expensive.

That will be fine, I've had upto 80 subtrim and no problem.
