Fun steps assembling the Trim and Autopilot systems


I started by finishing up fabrication of the two brackets for the Elevator trim. Then on to cleaning and priming all of the parts. Queue the fun, assembling the pitch trim. This went smoothly until testing, the servo hit metal before reaching the internal stop. Need to think a bit about how to correct this, I can’t see any possible…

Just 300 more to go on the Horizontal Stabilizer. Also knocked off was riveting the wing gap fairing. Went to start on the wing skins only to…
