Hey i got an Traxxas e-revo 1/16 in christmas present and discovered some problems...

1. When i'm going to go backwards i need to press the drive thing 2 times and then it go backwards, (and on long range it only works to go forward) sometimes the backward doesnt work too!

And now the second problem, when im turning the controller off and the car still running the wheels start to move around and then it stops.

And yea 1 more thing, can i drive in the snow and dont need to worry about water?
