I'm now trying to wrap up a number of to-do items on the wings, one of which was to install the roll servo (again). Doing this while working through the inspection hole is not as terrible of a job as it seems, as long as you have skinny arms and you can work by feel. I torqued all the servo mounting hardware and the bellcrank pivot bolt, but I left the servo pushrod hardware loose since its length will need to be adjusted later.
I ran new wires through the wing for the servo, and used a couple of adel clamps to keep them securely constrained so they won't get tangled up with the flight controls:
The pushrod hardware called out by Garmin makes for tight clearance between this bolt and the servo housing, but it's probably adequate. I'll check this again when I'm doing the final rigging and control checks.
To test the new servo and wiring I wheeled the wings over to the fuselage and made some temporary connections with alligator clips:
Technically, the wings are now "connected" to the fuselage!
All is well with communication to the roll servo, so I can check this off my list:
