Elevators Installed And Working
Spent most of the day tweaking the elevator upper and lower pitch limits of 30 deg nose up and 25 deg nose down. To do this you need to grind away (per plans) at the forward and aft control stops to achieve these limits. The new digital level I bought off Amazon came in super handy for this task. I'd been using an inclinometer app on my phone but it was unwieldy. It took hours because I constantly needed to remove and replace the left elevator to adjust the forward F-1411E Deck Doubler nose down stop. There was no way to get at it with the elevator in place. I had to remove a fair amount of material on the aft F-1412C Deck Angle to achieve the proper nose up angle. Vans doesn't specify any limits on the amount of material that can be removed to achieve the required control throws. Only that you remove the minimum required. It seemed like a pretty big notch I had to create in the Deck Angle but that's what was required on my plane. Since its a load bearing structure I'll email a couple photos to Tech Support and get their take. Not sure there was any other option. Every plane is different. From there I got the aft pushrod installed uneventfully and hooked up to the mid fuselage bell crank. It was super satisfying to watch the elevators move up and down as I manipulated the stick in pitch. There was zero friction or play in the system that I could detect. All my previous work to root out friction at the bearings with proper shims was worth it. As a bonus, both my elevator counterweights, which I'd bitched about in my previous post for being slightly off yesterday, matched perfectly today with the pushrod installed.

Both elevator horns neutral. Notice the right one is slightly aft of the left one due to manufacturing differences. The nuts on the bearing bolt and aft elevator spar are not AN. I'll replace them when the stab/elevators are on permanently.

Both elevators in full nose up position. The right notch needed to be deeper since the right horn sits further back.

Forward control stop notched for the full nose down position.

Digital level super helpful. The tolerance was 30 degrees up, +0.0/-0.5 degrees. I elected to go with 29.7 which met the tolerance but didn't require me to remove any more material.
