SpeedMax-40 is an advanced, single-channel, 40 Amp Electronic Speed Controller with programmable brake and BEC cut-off voltage, driven by a powerful RISC microprocessor and employing the latest MOSFET driving techniques, including variable frequency PWM and reverse exponential power curve. Non-reversible, controls one motor, best for use with a weapon spinner or airplane propeller.

The programmable cut-off voltage is essential for protecting LiPo, NiCd or NiMH batteries from over-discharge which damages them.

This is a perfect controller choice for our Speed-400 Ant weapon motor, as well as just about any motor that draws up to 40 amps!
