hey guy, this Jeff building a xenos b quick build. I'm loving your videos, watching them over and over. just got done riveting glaresheild and test fitting windshield skirt and windshield. that's a pain. slowly step by step. taking a break while brainstorming and also watching and reading about installing windshield. thank you. one day I do a video :)
Looking good Andy. On my build, I ran wires in the leading edge. There are three 1/4" tooling holes in the nose ribs and I pulled poly tubing through all three. It would have also worked to upsize one of the tooling holes for bigger tubing. The advantage of wiring in the leading edge instead of the main section behind the spar is cabin access. If you go in the rear you only have the small fuselage hole that you share with the aileron pushrod. Up front there is a lot more room to run that wire out and make the connection. I don't know if the B model plans show opening up the space between the two lightening holes on the root nose rib or not. Most of us have done it to get more room for connecting the flap torque tube to the pushrod. Again, that makes wiring access easy.
Hi Bryan, The B does not have an opening forward of the tunnel as does the A, so only the hole for the aileron pushrods. I am still wondering how I get the pitot/static tubing into the cockpit, as there is only a very small space in the tunnel. I know the two mounting blocks on the spars themselves are practically tight against the walls of the tunnel, leaving only around 10mm [ 3/8] or so clearance, from spar thickness to tunnel wall…hope that makes sense? As far as tooling holes in fwd/aft ribs there is only the chord holes, 2 in each rib, so effectively 4 in total. I am planning to open the aft chord hole to the bushing size same as for the pitot/static and use a similar tubing size.
@@pandyseven Interesting, I didn't realize the B model flaps were so much different. I see now that there is a flap torque tube behind the seatback bulkhead/framework. I'd ask Sonex how to route wires and the pitot static lines into the cockpit, if it's not in the plans.
I used 1/4" OD Polyethylene Tubing. Found 25ft of it at my local hardware store for about $5. The tube wall is sturdy and i was able to fit all 4 wires for my lights through the tubing. I bumped the mil spec aviation wires up to 18ga (20ga probably would have been fine, but I figured it would be worth the very slight additional weight). No need to increase the size of the holes that are there.
I should also mention that I originally had the conduit running through the forward ribs, but later opted to run it through the front tooling holes in the rear ribs to keep them (mostly) away from the aileron controls, while still guaranteeing that there was an opening into the fuselage.
Probably should have gone to my local hardware to get the tube, but elected to get the same as the Pitot/Static from Aircraft Spruce, that exercise cost me $130 AU…In the short term will use a draw wire as I don’t have my cables for any wiring as yet.
Perfect balance of music and narration. Thanks! She’s looking good, sir!
Thank you kindly!

Well Done on your Xenos, hope to see a video and or pictures of your build...what platform are you using for the step by step document..EAA website?
I love seeing progress in all the plane builds I follow .
we as builders 100% agree with you on that one
@ til I can start building my own ,,,,, people like myself get to live through the things you share .
Hang in there Joey, it will happen one day.

I guess my best bet is to check with Gavin, he is at that stage ...almost

@@pandyseven ouch. $130 is a lot. Either way, I'm sure it'll turn out great.
@dan_der_flieger Thanks, Dan. I can only hope
