These beasts generate a ton of heat. In every power conversion starting at the batteries all the way to the traction force to the ground, there's an energy conversion loss at each step of the process. DC current fights its way through copper to the motor controller, current gets turned into PWM current at the controller, PWM current goes through more copper to the motors, in the motors current gets converted into mechanical rotation, high speed rotation goes through a reduction device then to the drive wheels. At every step there's a loss of energy because no power conversion is perfect. Whatever erg of energy doesn't get converted to the next step is dumped as heat into your paintball spewing r/c vehicle of death! Add the fact that most paint their tanks in nice dark colors that loves to suck-in the afternoon sun, our models get VERY hot inside and one needs to give cooling a high priority when designing and building their tank.
