I started a new build last week, still a work in progress: 32" WS, 28" tip to tail with a KFm4 airfoil (5" chord at wingtip, 2.5" KF steps at wingtip) - based on the hand drawn plan of the FauxJet. Built using a very large sheet of 5mm foam board (no joints, just layers). Fuse will get a few extra hollow layers of enclosure on top for electronics, and a narrow skid layer underneath. Not quite a profile, not quite built up - just enough to house everything nicely and keep the weight down.
Added an 18" spruce spar/support across the wing section to stop the wings flexing up and down as much as they were - channeled out the top section of the wing and glued in the spar using 15min epoxy. Covered up with glass tape to keep things tidy.
Weight so far is 358g (12.6oz) and it'll probably grow another 90 before adding the electronics in the form of more foam for the fuse shaping and the motor mount. AUW is estimated to be around 650-700g.
Planning to try the following electronics:
