Investigate angled landing gear - modify Peggy 2 but not too much
Rigid top cover - maybe fiberglass + molds
Motor shields - integrated into motor mounts
Aerodynamic cabin using 3D printed molds and vacuum bagging
I want to try out 3D printed mold and vacuum bagging on a very small part, maybe a mini air-foil before we do something big. This will use some small amount of C.F. but worth it for learning imo.
