Unfortunately, most fall from a total loss of power. There would be no way to activate the chute. Unless you use a "dead man" type setup or add a small wing/surface of some sort that will disrupt the aerodynamics on the way down.
I crashed mine into the lake in my back yard 4 weeks ago. It experienced a total loss of power while hovering at 65'. It fell straight down and landed directly on the camera. Yuneec replaced the unit after seeing the flight logs.
One of the daily deal sites has the reconditioned cameras for sale now for $199.99. I dont think this forum will allow me to post the name. I may buy one as a spare for that price.
