Was trying to figure out how to get the elevator trim actuator mounted with the optional stiffener. They designed it so one side of the actuator actually mounts to the stiffener but plans show the bent-up part of the 'L' angle on the side of the mounts. I inquired of Zenith with the thought that if i were to just flip the 'L' angle it'd be fine. They said "flip it". Thumbs up, flipped it.
Also, in order to level the actuator on the skin since one part is on the stiffener, I built a riser on the other side, and wrapped it like a sleeve so the A5 rivets (I had drilled out the actuator) have a metal part to press onto instead of plastic. I also put a metal rail on the top of the stiffener side of the actuator.
Installed with no issues.
