I was wracking my brain for things that would be easier to do with the wings before I moved them and decided that I might as well firm up the location of the OAT probe.

Vans doesn't give any guidance whatsoever on this for the RV7, and actually Garmin doesn't say much either; basically that it needs to be in free air outside of the engine exhaust.

I had previously looked around to see what most people do here and the general consensus is under the wing in the general vicinity of the pitot tube location seems to work well.

Lots of people have put this through the inboard underwing inspection panel so they don't have to drill a hole in the wing. That way if they want to move it later they can just get a new cover to get rid of the hole. I don't like the idea of having to deal with this probe whenever I need to pull that panel off for something, so I elected to drill the hole aft of that panel. Nothing special about the location, It's just a couple of rib rivets aft of the aft edge of the panel and inboard of the adjacent rib rivet line 1.25"

This location keeps it close enough to the rib that the skin is pretty stiff, but exactly 1" away from the rib flange. so it's not too crowded to get a wrench on it. It also allows the wire to transition into the existing conduit without having to make any weird bends to avoid the aileron push tube.

Glad I happened to think of this today. It sure was nice to be able to drill this without having to lay on my back with shavings dripping into my face.
