This is the Mamba Max Pro 1/10 Sensored/Sensorless ESC with SmartSense. SMARTSENSE brings the best of sensored as well as sensorless ESC technology together to create the ideal controller for serious 1/10th scale enthusiasts. Operating at up to 6S, Mamba Max Pro can handle nearly twice the power of the market standard Mamba Max!

SmartSense uses the motor sensors to start the motor and then it switches over to Castle ultra powerful and efficient dynamic sensorless mode which boosts motor efficiency. Simply put, you l get more power and less heat from your motor. Sensored Only mode runs sensored motors using sensored timing only.

CHEAT MODE, Castle High Energy Advanced Timing allows users to electronically advance their sensored motor timing to extreme settings. This can often yield just that extra bit of power needed to win the race. Be careful xtra power comes with extra motor heat!

Castle Sensorless controllers offer best in class start up and braking which are fine for most users. Sensored only motor operation cannot deliver maximum efficiency. Sensors are also terribly inaccurate for motor timing purposes because the motor magnetic fields change under load or at speed; that where Sensorless operation shines. Sensorless is also more dependable. There are fewer wires and connections that need to survive the incredibly rough treatment most RC cars and trucks endure.

Sensored operation is required by the racing world rules, but it also offers slightly better start up and braking performance. Because of this, the Mamba Max Pro has been designed to offer the ultimate in flexibility and can be used with sensored motors as well: use it with all your 1/10th motors, sensored or sensorless!
