Dear Bruce,
I wonder why not spending more time into a well proven system that safed a lot of lifes so far, which also could safe a lot of copter parts, impact to others properties, and even human injuries.
A recovery parachute with a convenient deployment container could safe a lot of time, money, anger and pain. This barely makes not much sense on lowlevel FPV racers - BUT on aerial or fpv flying above 10-15m agl.
Who has lost a copter midair due broken ESC, motor, proteller, pilot issue, rf interference...?
100gr extra weight sounds much, but how much compared to a total damage?
