I clamped the elevators in the trail position, then took various measurements and noted the following issues I may (or may not) have to work out:
1. With both elevator counterweights perfectly aligned with the stab skin, the elevators are about 0.3 to 0.4 degrees different. Not sure if this is a problem or not. My gut says no.
2. The right elevator horn rubs slightly on the side of fuselage deck. I will trim the opening in the deck slightly.
3. The maximum elevator deflection is currently about 20 degrees, so I'll have to trim the "up" stop.
4. The maximum down deflection is currently about 25 degrees, and the horn hits the flange of the stab spar before it hits the stop. Since the deflection is adequate right now, I may have to fabricate a second stop and attach it to the fuselage deck or the elevator horns.
5. The elevator horns are slightly misaligned by about 1/8". This is very common with RVs, and should not be a problem as long as I assure good edge distance for the pushrod attach holes.
I clamped the control sticks in the "elevator neutral" position and checked the positioning of the aft elevator bellcrank and where the rod end meets the elevator horns. Both look great.
