Greetings,



I'm planning on completing my aircraft with a minimum electrical system 

and providing a way to install wingtip lights later.  Any experiences 

anyone has with using different types of conduit in wings would be 

appreciated.



Thanks in advance,

Hi Ray,I used 5/8-inch OD HDPE tubing from McMaster-Carr (www.mcmaster.com) through the lightening holes in the leading-edge ribs of my Murphy Rebel Elite.  I supported the conduit at every other rib with Adel clamps.  I haven't installed the wings yet, nor have I pulled any wires, so I can't give you much info on how well it works.

Ray,

                On my Murphy Super Rebel, I used some ½ PEX tubing I had.  It weighed roughly the same as the alternatives, and I like the smooth walls for pulling wires vs. the flexible conduit.  It also had a higher temperature spec than the flexible conduit.  I attached it to the ribs with aircraft grade zip ties.  To keep the ribs from cutting into the tubing, I purchased some door edge guard material from a local auto shop.  It came in 36” strips and I cut it up so the tubing and the back of the zip tie were pulled against the edge guard vs. a sharp rib edge.  I anchored the tubing to the root rib with a PVC Pex coupling that I cut in half.  That gave me a flange on the outside and the pex ribs on the inside.  I used proseal to mate it and a clamp, then removed the clamp when the proseal dried.

EMT (thin wall) conduit is still heavy - a little here a little there adds up.   Ya, Plex isn't bad - light.  One I used on another UL type aircraft is drip irrigation tubing.  Another factor is what burns and what doesn't, might be a factor to consider for fire spread.

Thanks to all who wrote.  Fire is a concern with some of the plastic 

conduit mentioned.  I'm concerned about just pulling wire and leaving it 

loose to rub on wing ribs, even with grommets.  I'm thinking some very 

thin wall al, if I can find it.  If I could find some fire resistant 

composite tubing, I'd look at it but I think it might be too expensive.



Thanks again.

I used 1/2 inch CPVC pipe and plastic pipe hangers.  CPVC is lighter 

than regular PVC and it used for the hot water lines in motor homes.

I've been told by a plastic manufacturer that cpvc is about the worst 

plastic out there for toxic smoke if it ever does burn. The translucent 

poly pipe used for things like ice maker water supply lines might be a 

better choice and more flexible if that matters. Several sizes 

available. I do favor non conductive conduit rather than metal. It helps 

to leave a string in the conduit if you plan to pull extra wires through 

later. The previously mentioned plastic snap in grommets are handy for 

running conduit through metal ribs.
