That is usually how they say it is legal but ban it. like guns in DC, and maryland. yea, you can have one see there is a law letting you. that you will never get one is your problem.
I've been thinking a drag streamer to stabilize the tumbling before deployment, the shape is not very friendly for the cords to the chute getting entagled. Not very gung ho to test how they tumble out of the sky myself to get data. plus 400ft to ground doesn't give you much time. so drag chute to pull parachute is going to be needed, just like base jumpers use. But they don't tumble and spin end over end. At least the ones who walk away don't.
Maybe those airbag inflaters, you should have a couple from your car at least you can use. They might blow it out fast enough to stop the entanglement of drone
