Adel clamping of wiring in wings at rib 3
Previously I created standoffs from plastic tubing, combined with cable ties to stand the cable bundle off ribs 3. Consideration of possible failure modes and consequences led me to use Adel clamps - 3/8" for the right wing and 7/16" for the left wing. The existing 4mm holes were upsized to 4.9mm by hand application of a chuck reamer. AN3-4A bolts were obtained, with one thin (1/32") washer under the head and one thick washer (1/16") under the (nylock) nut
