Once the left wing was complete, the right wing was alot easier. The left wing had more wiring and the pitot heater. That took time in trying to figure out how to place the wiring and drilling out the pitot bracket. The right wing had only the wiring to the wing tip. I used old oxygen plastic (O2) tubing to line the large rib hole where the wire tubing runs along the length of the wing The black conduet tubing (with the wing tip wiring inside) is resting on the oxygen tubing and secured by plactic tie downs. I sliced the plastic tube so that it would fit over the rib opening. I use glue to secure the tubing. With the black tube resting on the plastic O2 tubing, this should cut down on the chaffing on the black conduet tubing. Each rib is lined with the O2 tibing for a total 0f 14. I also did this on the left wing.
