John asked You mentioned a 2" x 12" Aileron trim and then you mentioned you needed to enlarge it? is 2" x 12" the final size you feel that works well?
Does the 2" x 12" trim (flap) extend past the trailing edge of the aileron, or was it cut of the aileron to make the flap? My aileron trim started out as a servo imbedded in the aileron connecting to a 1 inch by 12 inch long piano hinge. One leg of the hinge was inserted into a slot I cut into the trailing edge of the aileron so the hinge pin was oriented at the trailing edge. The first flight test was flown with only the 1" leg of the hinge as the actual trim tab. We found that that surface did not deflect the aileron enough so I pop riveted a piece of 12" x 2" sheet metal to that hinge leg making the exposed tab about 24 sq inches. That seemed to be enough. John wrote Also it seems to me that if you could have an offset bellcrank (or something like it) perhaps you could increase stick movement with less cable movement close to center, and increase the cable movement as the stick extends further away from the center, like variable power steering. This would still allow you to get the full elevator movement, and reduce the close in sensitivity that everyone seems to have problems with when starting to fly. Has anyone done this??? Some people have talked about a longer stick to help that issue. One of the things I did was to make my cable connections from the elevator to the stick an inch closer to the pivot point so the travel was a little less. It didn't change the full deflection very much at all and as I said in my post I use very little stick for a lot of control. The movement of the stick is not more than an inch overall. I think this is an issue that you can get used to very quickly. My only point in the post is that the plane is a high performance aircraft and excessive control input should be considered on your first few flights. I wouldn't want to modify the stick so it responded like a 152. I will try to get some photos to Mark to post on the web site as soon as possible.
