I'm not a multi copter pilot, though I'd like to be in the future
I have watched many videos, and some more interesting videos are seeing these thrust based aircraft plummet from the sky when losing all power.
I was curious if we could develop a plug and play recovery system consisting of:
-A-B size rocket
-Igniter / onboard battery
Maybe something like this has already been developed and I'm just behind
But imagine a self deploying parachute system for your expensive copter, in the advent of a power loss at any altitude
