Ouch! I've had my own crash recently with my
I2.
I was out giving it a test flight after a firmware patch. I got some interference and it switched to ATTI mode on me suddenly, then got hit by a gust a wind at that exact moment which caused it to suddenly drift to the left and smack into a utility pole. Then I freaked out and went left instead of right, the props ground against the pole, and the whole thing came slamming down 20 feet on it's back where it did it's best job at trying to burrow into the ground until I was able to shut it off.
A month later and 400 dollars spent, I got the bird back up in the air and fully functional. But, I did learn quite a lot about how it's put together, what sort of things are in it and how not to break the connectors (I broke the forward vision system messing around and slipped with a small screwdriver.).
Still, when it happened, I thought I was gonna die. I feel your pain.
