Theres a video on youtube I saw a while back. Guy has a falcon 3d and a blade cp. Its all snowy outside and he is in the backyard trying to fly. Snow probably 2-3 feet deep and looks more like powder than hard pack.

He crashes both of those helis so much in the video that I felt pretty bad for him, they would just get entirely swallowed up by the snow. The whole time he flies you can see he is fighting the heli, always a 1/4 second behind the correct input. Someone ought to buy him an airhog or something lol.

Personally, I would wrap my electronics up with something as some of them are pretty exposed. Looks like fun though, and I bet it could be almost like an airbag.
