Stick Length
Tim,
On my new RV-8, I cut the bottom of the instrument panel up about 1 1/2" to allow me to use a longer stick. I also welded an 'S' into the top of the stick to move the grip aft about 2". The RV-8 stick is too short, and too far forward for me if I don't do this. On my previous bird (RV-6), I made the stick with grip just clear the bottom of the panel. I fact, if I had my thumb on top of the stick, it wouldn't clear the panel bottom. I never actually came close to getting the stick under the front of the panel while in flight, but I would never build my stick too long to clear it. Basically, make the stick as long as you can to clear all obstructions in the cockpit (with grip on of course). If you ever plan to fly formation - the longer, the better.....
