Hi All
I've reached the point where I need to install the pitot tubing and a couple of tubes for the Lift Reserve probe plus electrical cables. The manual calls for boring a hole in the wing spar. I am probably over thinking this but I'm uncomfortable boring hole in the main spar. I was thinking of running a piece of aluminum conduit under the spare and attaching it to the rib just outboard of the fuel tank (with appropriate fabric glue plates on both sides). OK...a wing wart in process. Thoughts?

Re: Pitot tubing routing
I also have the pitot and AOA tube and I broght both of them to the wingtip and down the trailing edge wing tuben to the fuselage. That way if you ever have a problem the tubing is easy to replace. There, also, is no issue folding the wings.

Re: Pitot tubing routing
I ran mine through ribs and then through a gap behind the fuel tank. No hole in the spar.
If you are using a Rotax 912, you could install the pitot tube RV12-style. It goes through the spinner and skips all the wing routing. Run a rigid tube through a bushing in the spinner, through the hole in the center of the gearbox and clamp at the back. There are threaded holes on the back of the gearbox that you can use to fix a clamping block. then attach your flex tubing to the back of the pitot tube and make a short run to the back of the instrument panel. It's simple and has the added advantage being in undisturbed air. (unless you're going backwards)
Obviously this won't work for the LRI tubing.

Re: Pitot tubing routing
I saw on Steve Henry's site where he mounted his ADAHRS in the wing, making an nice short connection to the pitot. Looks like a good idea to me. Not sure what he did for static--I would guess he just left that port open to the wing compartment.
