I'm currenly working on this stuff. The stick columns delivered in my RV-7 kit is way to long (both sides). Any ideas how can i figure out the right lenght?
I did make sure the sticks (and my thumb) cleared the panel and the center throttle/mixture bracket. However, after installing the throttle and mixture cables, I had to remove another inch from the pilot-side throttle. I'm very satisfied with the results.
Search the VAF archives: there are several discussions on this...should be helpful.
