SP-520 PLUS Electronic Speed Controller

Thank you for purchasing the HITEC SP-520 PLUS electronic speed controller with reverse.

This unit features competition grade performance with reversing speeds in a fully proportional

mode. It can handle stock and modified class motors, with Internal TEMPFET sensors to prevent

overheating and damaging the unit. Additionally, the unit is polarity protected to prevent damage

in the case of an accidental reversed hook up. The SP-520 has the highest power output and best

power transfer efficiency in its class.

Page 3 6. REVERSE To use the reverse function of the SP-520 PLUS, simply move the throttle stick or trigger on your transmitter the opposite direction of full throttle. There will be a very slight delay before reverse power is applied to the motor from the controller, and this is to prevent damage to the gears of the car.
