About 10 days ago I discovered that the PVC conduits I ran as spares interfere with the W-818 aileron push rods. Tonight, all I did was drill out the rivets holding the brackets that held the one in the left wing. I'm thinking that the existing corrugated conduits will be adequate for all the non-RF wiring in the wings like that serving nav lights, landing/taxi lights, stall warning & pitot heat (left wing), and roll servo (right wing). I believe I'll add snap bushings or grommets for an RG-400 coax in each wing for any antennae I might later decide to install in the wingtips.
