Decided to place the OAT probe just inside the Outboard access panel. It is a 3/8" hole the same way the Pitot tube is. The OAT probe will be wired to the Remote compass at the wing tip.
3/8" hole with a nylon washer
And the nylon nut with Loc-tite
The wire runs along the top of the RIB and then out to the wing via rubber grommets.
