Back at work after a too-long break. First task for today was to fit and drill the left elevator’s electric trim mounting plate and brackets. The plans-specified mounting dimensions for the mounting brackets may not be quite right; if you use them, the trim servo’s control arm may not be centered in the mouting plate cutout. I adjusted the servo/bracket assembly on the plate until the control arm alignment was correct, then match-drilled everything

Here’s the final result after deburring, dimpling, priming and back-riveting. Not too bad.

One other gotcha. The rearmost rivets on each mounting bracket (kinda hard to see in this picture) will probably interfere slightly with the trim motor itself. I test-fitted the motor, then gave those rivets a couple extra whacks with the back-rivet set.
