I also thought about making it one piece, but left it, the only possible disadvantage is the servo connectors will be exposed and or how do you attach them to the strut at each assembly.

I took my servo extensions and ran them up into the center section, the servo extension wire is held to the strut with black electrical tape, which make the wire running up the strut virtually invisible, and the servo connections are concealed in the wings.

I've got about 8-10 flights in with the new motor, I for sure need to do something about the color scheme,, just to hard to pull out of the sky..

Another things I'd recommended. Take some thin CA and wick in some glue to harden the tabs the outer struts attach too,, the ply isn't very strong and I've had to repair them,, the crash probably didn't help, but the wood is weak.

good luck
