    In a sense. Brushed motors are not harmed by water, although brushes and bushings will wear a little faster. Brushless motors, well, thats a big debate. They are sealed, which should keep water out, but if water does get in it will not drain out, and could corrode the inside of the motor.

    I understand what you mean. You would think so, but apparently it will not hurt them at all. In fact a commom way to brake in motors is to run them underwater

    So, driving my rustler in a puddle shouldn't hurt the motor?

    Right, but if the ESC is waterproof, and it is a brushed motor, you should be fine. Just oil the bushings when you are done.

    The problem with that is that ESC's need some airflow around them to keep cool. It's not like a receiver that you can just stick in a balloon...ESC's are power electronics, they must dissipate some significant heat. Better if you made some sort of box or shield for it. Even then, you risk frying it or at least sending it into thermal shutdown. ESC's are the main obstacle to running electric vehicles in wet conditions. Ideally I want a waterproof ESC.

    Brushed or brushless motors are water proof. Obvisouly if you get a bunch of scummy water int he motor and bearings it wont be good for them and you should do some maintenance to clean and relube the bearings but the water will not hurt the motor electrically. The ESC, receiver and servos are a different story.

    I found the video I was think of....

    The brushless motors ARE water proof.


    and this is from Shawn Palmer, Marketing and Product Development at Castle Creations

    "The circuitry is silicone conformal coated just like the Mamba 25's. Legally we can't say "waterproof", but the Mamba 25 was video tested by a forum user a while back while fully submerged without any problems whatsoever. The same process is done to the Max. From my own testing and driving (poorly) I've never had an ESC have issues with puddles or snow. Receivers however are a different story.... we've soaked, splashed and submerged more than our share and most of them never "come back to life". The Max and 25 ESC's in those same vehicles were always A-OK."

    is that also the esc submerged along with the motor ?
    if yes, it apears like silver sealing on it's bottom side ( not sure ), so somebody correct me please.


    does this mean that all max mamba ( motors & esc ) are water proof but not officially declared by castle creations ??

    That video is not a Mamba Max but a Mamba 25 which is made for 1/18th scale cars, and yes the ESC was submerged. The Mamba Max is not sealed the same and as mentioned can not be submerged like that but all Castle ESC have a protective coating on the circuit boards which is said to make them very water resistant.

    The Formula Pro BB would be best for him, but his budget doesnt allow.
