I had my first crash last night. It hit a tree (about 15 feet up) and fell into about 2 feet of snow. It is recovered, I saw it hit and fall, it was only about 30 ft or so from me. After it hit the snow, I shut the motors off and grabbed it took it inside and wiped all the snow off, took the battery out, and dried it off. No snow got on the camera, some got on the side of the battery. It was wet snow. I'm positive that nothing got wrecked on it (other than props). So, the question I have now is, what (and how) do I need to check on it to make sure it runs smooth?
