I am really happy to see Castle going in this direction. Not so much the motor 9although their motors are tops) but more so with the ESCs. Obviously the the ESC talked about here is waterproof but also they are doing waterproofed ESCs for couple of HPI cars. Can't wait till they start selling the MMM as waterproof unit. I know you can do it yourself but having to say goodbye to your warranty isn't exactly all that good. Keep up the great work Castle.
