This is pretty nuts, part of me thinks it is a waste of time in the sense of not being practical useful but another part of me wants to make it because it is cool.
I haven't simplified the design enough yet... so I tinker with it from time to time.
The concept is using the gyroscope of the 9-axis accelerometer, the tumbling-airborne drone can tell which way is "up" so to speak that is which way is the opposite of gravity. Knowing that, the neutral-blades will engage positive pitch opposite of gravity to start flying.
It should be simple like a drill, where the battery is hemisphere, that simply slides onto the other half which contains the majority of the sensors/electronics/payload/swashplate/motor.
It does seem like a gimmick but the ultimate gimmick is a muscle-memory-wire-gel-blade design which uses embedded muscle-memory-wire to change the pitch of the blades through induction swashplate... as opposed to mechanical linkages but that's pretty insan
