Stephen,
You can get all the adjustment that you need by making your seat cushion thicker or thinner. There is not a whole lot of room to work with anyway. The more forward you can sit, the better. Leave your rudder pedals where they are. Keep everything as forward as you can. I don't see how mounting the stick on the aft side of the main spar avoids extra holes in the main spar. The hole has to be there whether the stick is on the front of aft side. However, I don't see any way that it could be mounted any other place than on the aft side of the spar. As far as I am concerned, the only way to go on this plane is with dual sticks like we and Mark L. have. I flew a KR for 185 hours that had a center stick and that is one of the most aggravating things there was about the KR. You solve a lot of issues by using dual sticks or at least a pilot stick that would be in the same place as if you had dual sticks.
