Terry,

Coomarlin is correct. You want to use the linkages to set the desired position first. The subtrims are really only meant to make fine changes. A large displacement, more than 10 points or so), should be done with the linkages first.

In your case, see how much deflection you need, center all of the trims, and adjust the links on your pushrods to get as close as possible. The next time you fly, you should only need a point or two of trim. THEN you can use the subtrims.
