Brief Description:  Secured elevator trim tab cable connection

Spent much more than 1 hour today tying the 4 ft led shop luminaires together with 1/2x3/8 Al U-channel and neatly tye-wrapping the extension cords to the scaffolding.

Drilled two #40 holes in the left side of the rear deck underneath the vertical fin to immobilized the DB9 connectors for the elevator trim motor and its cable running forward to the panel. I put two double-strand lacing tape cinches in an "X" pattern across the connected DB9's, attaching it firmly to the deck. The cable, inside a corrugated plastic conduit, is well separated and immobile against a left side fuselage stringer. No chance of it interfering with the elevator pushrod. See images 1 and 3 (the second, x-ing lacing had not been applied yet.

The lead from the trim tab motor is laced in two places to silicone self-fusing tape wrapped around the shaft of the right elevator horn (see image 2), It forms a loop over the stab rear spar, and is secured with an Adel clamp on one of the spar hold-down bars. The loop has plenty of slack for full down elevator deflection. The top of the loop is far enough away from the bottom vertical fin rib that it doesn't touch with full up elevator. The flexing is, I hope, gentle enough to last a good long while. We'll see.

Calibrated the widgets on the Dynon EMS screen for elevator and aileron trim. Very stable readings (to 0.01 V) of the pot voltages from both trim actuators. Very cool--makes me want to put in a flap position pot, but I'll try to ignore another time-eating mod that doesn't need doing before airworthiness and first test flights.
