DJI DropSafe is an parachute system for DJI multirotors s that launches a parachute in the event of a power failure. DJI calls it a “drop speed reduction system,” and does not guarantee that it will protect equipment or prevent injury.
The DropSafe weighs less than 550g (20oz), and can be set up to automatically deploy. When needed, it shoots out in less than 0.5s, automatically killing power to the rotor blades so as not to get tangled. It’s even a reusable design so you won’t need to buy a whole new one each time.
