I'm thinking about how and where to mount the GRT OAT probe. I've been through several searches here, but the threads that I found had to do with other manufacturers.
Here's a nice secure OAT probe installation from JPI:

My concern is that the GRT probe is not very secure. I am hesitant to drill a 1/4" hole in the bottom of the wing for the probe. I'm thinking of screwing the bracket into one of the ribs out by the pitot tube. Then using RTV or proseal so that the probe can't be pushed into the wing, leaving a hole.
What do you think?
