I have been working on a pusher design, using hot wire cut parts (a close approximation could be built using FT folded foam board techniques).
Right now it is sitting at 148g dry (and I see at least 5-10g of wire that could be trimmed down/out) and the goal is to use a 100g 2s li-ion battery for endurance.
CG calculator info: cCalc CG [0.98 - 1.22 in from leading edge]
WCL [@ 250g AWU]: 10.8
Glide test results from initial glide test attempts: Wing construction Glide Tests - kfm-2 vs FT folded vs hot-wired.
Glide tests on this model (had to move CG toward the farther back area of the suggested and give a touch of up trim) my son was barely able to grab from ~20ft away as it was climbing from a firm throw. I figure it has somewhere in the 10:1 to 20:1 glide ratio and doesn't seem to be very draggy.
