I discovered another feature for the leg extenders: CRUMPLE ZONES!
I unintentionally put my Phantom 2 Vision+ into an unrecoverable Vortex Ring State and watched it rapidly descend straight down from about 100 feet. It impacted an asphalt driveway, bounced once, bits flying off in different directions, flipped in the air and land upside down on the grass. I thought at the very least the gimbal was going to be destroyed but if I was really lucky I might be able to salvage some pieces. Amazingly, the only actual damage was to the leg extenders. Those were the pieces I saw flying off and apparently they had absorbed all the impact force. The gimbal showed no signs of damage and still worked. The only other damage was to the props, mostly grass stains and some bent blades because they were still spinning when it landed upside down. These leg extenders are the best 20 bucks I ever spent on a Phantom accessory and I am definitely ordering some more!
