I had always blamed my planes pitch sensitivity on the airfoil shaped tail and the gap seals.
I am building a new control column to lower the seat.The control column was partially completed when I got the project but fit so I did not question it. Since there were a bunch things that were different than the plans I started measuring things trying to figure out why they were built differently. I did not want to build something that did not fit. Most of what was different looked like solutions to mistakes that would have caused clearance issues.
The plans call for the control stick to be 9.375" from the pivot point to the top. Mine measured just over 12". I can't blame that on the previous builder since I built the stick. What I did wrong was put a teak wood grip on it that increased its length by 3 inches. Duh. The mechanical advantage was increased from about 3 to about 3.82. No wonder it had almost no resistance to stick movements during landing.
The reworked stick will be adjustable from a 7-10 inches. It allows both tuning the stick force and removal of the upper part of the stick for maintenance.
