interesting concept. might i suggest thin plastic as a cowl for your thrust fan?
and instead of sealin up the wheel wells, maybe you could link the ruder to some thin lexan fins that protrude from the wheel weels to enable more controlled turning and less side-side drift?
maybe an independent fan battery could be useful. possibly have 2 2s1p lipo packs and run the fan off one and the board off the other? that might enable longer runtime and more power for both fans. another possibility could be customizing an xmod gear to fit a plastic propeller of some sort to lower weight even more. the concept is very interesting i think.

another think i might add is that a 360 degree fan shroud may not be neccesary on the rear. i believe a dual rudder design will be sufficient (keeping weight down
