My RV-10 QB wings came with bushings installed for wing wiring. This is per my plans and also what shows in the RV-14 plans. Many previous posts talk about installing conduit in the wings instead. I am wondering about people's thought regarding staying with the Van's bushings or trying to replace them with the 5/8" corrugated conduit that Van's sells. I could run a few extra wires through the existing bushings to the wingtips, just in case, as I saw in another posting. That may be lighter than the conduit. Removing the bushings and opening up the holes for conduit may be difficult. What do you think?
