So I received a email from Vans today. The photo they commented on was the post #1 photo shown below.
They said "This additional hole will not be a problem."
So...As soon as I get my new step bit, I'm drilling the third hole
The ½" center hole will have my 14AWG heated pitot wires and the two ⅜" outside holes will have the pitot and AoA tubing. This way, I don't have to exit the conduit wth any wires or tubing on the way to the wing tip. And on the right wing, I can run my A/P servo cable through the ½" hole and all the wing tip light wires in the conduit.
My Garmin GAP 26 unregulated heated pitot should be here tomorrow
