more details design concept
1. high launch altitude
placed the peg far back from the CG to prevent a hooking launch and reduce air drug while spinning.
2. turning ability
by the benefit of 1, this DLG able to use short boom. it makes easier to turn.
3. stability
sweepback angle stable for the pitch angle.
4. mass balance
don't need to put a nose weight by the design. so all 4 servos can be put the inside of wing. it reduces air drug and brings mass balancing.
220g and launch's to 65 meters
