Jon,
Is that just a rubber grommet?

Sure is, Eric. I cut a small hole in the conduit and it popped right in.

5/16 airline
Eric.
Not my idea but we ran airline the full length of wing on both sides for antenna coax. It would be very easy to install now but bit tricky with skin on...slip coax right through to tip...especially year later when we added vor wing tip to opposite wing tip. It fits perfectly in the formed rib support ( forgot number) without drilling any holes.

You mentioned you already have bent the tubes. I assume you mean the aluminum tubing coming out from the pitot itself. Garmin recommends minimum 8" of aluminum, how much did you keep ? Do you transition to plastic before, at or after the bulkhead ?

I kept the full length of the aluminum tubing (2 pieces) (I didn't want the nylon tubing to melt when heat was on) on my Dynon pitot. A little thought to the bends, and it goes on/off with the skin on.

Bob,
That's exactly what I've done. Did you make a service loop in the vinyl tube that attaches to it? I can't see how to do it in that small bay so I think I'm just going to ease the pitot and AOA tubes back through the plastic bushing (pitot) and conduit (aoa) back to the wing root and make a loop there. If that does work out, I still should be able to get a hand back into that bay and disconnect the quick-connect fitting.
Jack - That's a great idea! Think I'll head to the NAPA Aircraft aisle this afternoon! I'm assuming you are referring to the j-channel, correct? Did you secure the airline to the j-channel in any way?
Thanks for the replies, guys! Right wing riveting starts tonight!

Eric
No attachment need except for where it enters and exits the wing. 5/16 may be hard to find at Napa...McMaster will get it to you next day. It is snug fit so installing now would save you some frustration if you go this route.

Thanks Jack! BTW - I think we've actually met. Possibly last year or the year before last. I was the newbie tagging along with Mark Cooper at the Prosser fly-in.
I do remember your beautiful '10

Water line for antenna conduit?
So I looked at McMaster-Carr last night and came up empty handed. It appears that a max OD to fit under the curved portion of the j-channel is around 3/8. Stein's site stated that the coax OD is 3/16. I couldn't find an air line that met that criteria.
But lo and behold, I had some leftover polyethylene water line that is 3/8 OD and 1/4" ID which would seem to fit the bill rather nicely.
Anyone see a reason this would be a bad idea? I thought about fuel resistance but this thing doesn't need to be air or water tight. Just need to provide a stable path between the root and the tip and provide a bit of protection from the rib edges.
Best of all, it's free
Thanks for any feedback!

Ed,
I'm just starting to work on my QB wings and noticed today that there is a set of holes in the left wing for the pitot tube run, but not for the AOA tube. It looks like you ran the AOA tube in the wiring hole/conduit. Is there a reason for this?
I was thinking about drilling a second set of 3/8" holes for the AOA tube similar to the pitot holes already there. Anyone know of a reason not to do this (structural ?) or suggested best locations for these additional holes? I could ask Vans but figure I would check in with the community first.
Thanks
Dave Macdonald
