This afternoon and this evening I spend several hours removing and tweaking the left elevator. The goal is to have free travel from 25 degrees down to 30 degrees up. Starting with the measurements in the plans I had 22 degrees down before the elevator horn contacted the bottom flange of the aft HS spar. It traveled up to around 35 degrees, but there was some slight running of elevator skin against the HS spar. After some careful measurements I calculated I needed to move the elevator about 2mm aft. I also found that the gap between HS and elevator counterweight arm wasn’t quite uniform. After several iterations of removing, adjusting the rod need bearings and reattaching, I was happy with the travel.
After backing off the rod end bearings approximately 1.5mm, the elevator can deflect down 25 degrees without contacting the spar flange.
