Built RV-9A. I have a new Dynon ADAHRS which requires a new OAT sensor, which I'm putting on the underside of the left wing. I've run the wiring up to the middle inspection plate, just need to drill the 3/8" hole for the probe. What's the best way to drill the hole? The wing skin between the ribs flexes quite a bit...can I drill that hole through the adjacent rib flange?
