OK. After moving from Kiama, NSW to Bonner, ACT we restarted the build. The new garage is now decluttered and the workbench visible.

Each wing is 1.6m long and was delivered in halves. We have now joined the foam molds and the wing halves with epoxy.

We have also completed the CF wing spars. 2mm rod into 4mm tube (2mm inside diameter) into 6mm tube (4mm inside diameter) giving 2 x 1.6m tapered spars.

Next step is to coat the foam cores with a 2-part water-based polyurethane. I received some free samples from Hychem in Sydney. This is the same stuff used to coat garage and shopping centre floors. Very tough. We'll sand most of it off again to give a strong skin to the flimsy foam before installing spars and covering with Koverall and more WBPU.

Question: I am planning to install aileron servos, spoiler servos, electric retracts and LED navigation lights (rc-lights.com). Should I install a majority of the required power/control wiring in the channel with the wing spars? Pics soon.
