If you're going to run your brushless in the wet make sure the Madrat body is velcroed properly to the chassis so as little water as possible can get in. Make sure you put some blu-tac over and around the hole that the sensor wire goes into on the motor and as long as there is no really bad standing water you should be fine. Just remember that any puddles could cack up your speedo/motor combo and it's NOT waterproof. If you are racing then inevitably it will rain some time and you might have to go race in the crap conditions. If you are not racing then my advice to you is only go out when the conditions are good, that way you won't destroy your expensive kit
