Got a bit more done this afternoon after sailing @ Puddleduck.
All wiring is now completed and the 600mw VTX installed in a 3D printed housing. Hopefully this will prevent the antenna sockets from snapping off in a heavy impact on landing.
New 3D printed VTX mount
Gimbal is now all wired up and working as well
Still need to fit the wings but the COG appears to be close to where it should be with the flight battery & all the gear installed
