I am installing a Dynon heated pitot/AOA probe in our tapered composite wings for Bob Mills' Rocket 6. The Dynon instructions are pretty lean on how to attach the probe body to the mount strut. The strut (I think it is from Gretz) has four holes at good locations to put screws into the body of the probe, but the probe itself does not have any threaded holes.
The Dynon instructions say not much, except that it is OK to carefully drill through the outer shell of the probe body. Looking at the probe, it is not clear that the shell is thick enough to match drill with a tap-size drill and thread the probe body for attachment screws. I'm thinking of using 4-40 100-degree flat head screws, but I may not get even two full threads in the shell?
Looking for experience from others - is there enough metal there to get a few threads tapped into it?
