 This is the O.S. OCA-170HV 70Amp 50V Brushless ESC.
Features:
- O.S. quality is now available in a brushless speed control
- The perfect complement to O.S. brushless motors!
- Cooler running with the latest generation FET
- Automatic battery cell number recognition
- Start protection prevents accidental starting of the motor
- Low-voltage cutoff stops the motor before voltage levels reach the point where control is lost and cell damage can occur
- No-signal cutoff switches the ESC off when signal from the transmitter is not received
- Overheat protection restricts output when temperatures reach high levels
- Anti-spark function reduces sparks that can occur when connecting the battery
- Opto-isolation prevents motor feedback from reaching the receiver and causing glitches
