Mine has done that for 5 years. No dents in the wing skin, though.

Thanks guys. I recall seeing a Sonex in this forum with clear nylon tubing running through the nose ribs. I have a bunch of pull string from when I buried 800' of conduit 3' underground to bring power from the road to the barn a few years back. I'll just slide that through some flexible conduit or tubing for later. I'm going to look around at Oshkosh and decide on what I want for lights and get them then. I'll be lucky if I get the other wing built by then.

You mentioned using 14 Ga. With modern LED lighting for position, strobe and landing lights that may be overkill and added weight. Check out what is recommended for the lights you are thinking you may use. For some strobes, may even want shielded, but might us multi-conductor.

You're right, LED lights don't require many amps. I'll have to see what other Waiex and Sonex builder's have used and see what new designs might be available. With the slanted under wingtips it is kinda challenging to get a position light isn't somewhat hidden. I suppose it can be mounted on some kind of built out extension but there's probably someone selling a mount or light to remedy that. I've already looked at a few and figure out that no matter what you buy it'll be 10 times what it would cost for a different vehicle like a boat or a trailer.

You don't need to put a string in the conduit when you install it, you can to what the Electricians do and use compressed air to blow a string through the conduit when the time comes to pull wires through.

One of this electricians favourite tricks is sucking a string through conduit with a vacuum cleaner.

To get my combination position and strobe lights out where they can be seen, I used a mount from Van's that is glassed in place high on the slanted wing tip. Also have seen some complete wing tips with this incorporated from one of the LED light manufactures, i think might have been AeroLEDs.

With the acro ailerons you can't balance to 100%, i.e. aileron level.

Can someone explain the reason why it is called out in the plans to fully balance the standard ailerons (within 1/2" of level at the trailing edges) while the more massive acro ailerons do not require full balancing other than being consistent with the left and right's imbalance? I'm glad this topic came up now as I've built my wing boxes for the acro aileron option but, as I get ready to make control surfaces, I'd like to pause to understand the rationale on the balancing.

Thanks,

I can't speak to the engineering logic, but the plans call for it and I confirmed with Kerry (after sending my pics to them) via email that it was the way Sonex wanted it.
