Crash fail safe?

Is there anyway to implement a crash failsafe mood? When quadcopter or planes crashes a system that stop the props and maybe activate some kind of emergency plan? like activating a beacon etc…

yesterday i had a big crash with a quad, inside a building but after it crashed pretty hard my props didn’t stop spinning even though throttle was all the way down. I could not even get close to it because of that. Whole time i was only flying using stabilize mode.

This is being thought about, no idea how far out it is.
