New from Fusion is this range of brushed ESC's called 'Airpower' which can easily be adjusted for use with NiCd/NiMH or Li-Po/Li-Ion batteries. (These ESCs function with brushed motors only!)
Features:
'Safe Start' - to prevent accidental motor starts by disabling the motor circuitry until the throttle stick is moved to full throttle, then to the 'off' position. BEC (Battery Elimination Circuitry) - which allows the motor battery to power the receiver and servos. When the motor battery voltage is reduced to a set voltage per cell, the low-voltage cut-off circuitry stops the motor while continuing to supply power to the receiver and servos, eliminating the need for and weight of a separate receiver battery. Thermal Protection - which reduces the throttle to 70 percent when the maximum temperature is reached.
