I worked on UAVs (drones, singlecopters, RC gliders, rockets etc.) in the past and I plan to engineer and test a rocket that uses an electric ducted fan (EDF) as its source of propulsion.
Problem: This technology is expensive and iterative development is needed, so I need a safety system that saves my UAV from crashing into the ground in case of failure.

In this video, I build a failsafe technology that detects critical flight behavior and deploys a twostage parachute system that prevents crashing into the ground.
