Sometimes it's just the little things. Drilled and mounted the pitot heater controller box. I'm not 100% sure if I'm happy with it yet. I may yet mount it on the back side (same holes) of the rib and access it through the bellcrank inspection hole. This is why I just put pan head screws and nylon selflocking nuts (little washer in there). I figure that it's pretty easy to still reach in through the inspection hole and hold a ratchet or pliers on the back side nut and screwdriver on the front. I may still just put a nutplate for each hole and make it much easier for removal requiring only a screwdriver from the inspection hole. Time will tell. I don't plan on perminetly sealing the top of the wing until it's in the hanger anyhow (I only install about 30 rivets for transport, easy to drill out).
I think I'll run the pitot power, ground (both are 10 gauge) and sensor (14 guage) wires through the grommets already in place for the landing lights. Lots of room yet, though I'll probaby clovehitch the pitot wires together separately from the lighting bundle.
