Update on stick clearance...
Thought I'd share my recent experience on this topic as it seems there was no "one size fits all" solution. I tried ALL the suggestions listed, but in the end it took all of them to get it right. If I had to do it over again, I would have started with bending the sticks, which is where it ended up anyway.
Here's my setup (see pic before sticks installed), Aerosport 10" EFIS panel. This panel has a section to right that "tilts" the radio stack toward the pilot. Also have Tosten CS-8 grips. These grips are different than the military style or Ray Allen grips in that they "tilt" more forward than other grips. This will add to the clearance issues if you choose this style grip. If I were doing it again, I'd still choose this style grip, because I like the looks and feel of it. It was worth the effort.
Attempt 1: Cut down sticks (top and bottom) and adjust control rod bearing lengths.... Was able to get stick clearance by adjusting elevator control rod ends only, but was not able to get enough deflection of elevator. 14 degrees down, 21 degrees up. Also, elevator up stop became the seat frame, not the stops in the tail.
Attempt 2: Offset bushing... Received an 8 degree bushing from Tosten. Was able to get clearance on pilot side with the bushing and adjusting control rod bearings. In this set up, got 18.5 degrees down and 25 degrees up on elevator. However, it hit a radio knob on right side. Needed something more.
Attempt 3: Buy tube bender at Harbor Freight for $120. (I was really trying to avoid buying this 1 use tool.) This thing worked GREAT! I was surprised at how much of a bend it took with the tool simply due to the spring back of the stick once pressure was release. Was now able to get 20 degrees down and full 30 degrees up elevator deflection.
Because I cut some off the bottom, I also ran into a spot on each side where the stick would rub against the seat frame. I had to file some of it off to get clearance throughout the entire left / right swing of stick while pulling full up.
Conclusion... There is not one fix that will solve everyone's clearance issues. I like the 8 degree offset bushing because it changes the tilt of the CS-8 grip to be more upright. This simply feels more natural in the hand. But, I could have solved this problem by cutting and then bending the sticks from the beginning.
