Wing wiring

The wings were wired with tefzel throughout, replacing the cables supplied with the kit.

Nav lights - 4 core shielded 18AWG tefzel MIL-C-27500 18TG4T14

Taxi lights - 2 core shielded 16AWG tefzel MIL-C-27500 16TG2T14

Landing lights - 2 core shielded 16AWG tefzel MIL-C-27500 16TG2T14

The gauge for the above is in excess (by one or two steps) of what is required for the LED lights now being used. I decided to stay with the original wire gauges however.

The left wing is additionally wired with power and sense lines for a pitot heat controller. Single core MIL-W-22759/16 tefzel wire was used, the choice of /16 (thicked insulation) making it suitable for open wiring. The red and black power wires is 12AWG, while the sense wire is 16AWG. These three wires were twisted together with an approx 2 inch pitch to minimise magnetic fields. The 3 wire bundle was secured with transparent heatshink tubing of 3cm length every 30cm.

I did not use the 16AWG single core wire provided in the kit (originally for the lights) as it is /18 (thinner insulation) for protected wiring. This would have required a sleeve.

The right wing is wired with shielded 2 core 18 AWG tefzel MIL-C-27500 18TG2T14 to power the FlightFlix 5V USB power converted for the inbuilt camera mount.

The wire group was bound with Tesa 51036 tape at all points of attachment points to the stringers. The cable ties used were Crescent 3.6mm black (carbon additive for UV resistance) nylon 666 UL approved.

Additionally nylon edge protector was used in key places to minimise the chances of cable abrasion. Where this is a possibility, Tesa tape was used to provide additional protection.

Note on 22 Dec the LH wing wiring was partly redone as the length of 12 AWG cable for the pitot heat controller was insufficient at both ends. The Tesa tape was removed, the longer cable inserted and the loom ties up as before. Now there is ample cable at the controller, and also 60cm cable emerging from the rib 1. Also some additional tape was applied to the landing/taxi light cables.
