Features: It is based on Simon firmware, further optimized design to the perfect drive performance.Parameters of the ESC can be set via program card or transmitter.Throttle range can be set to be compatible with different receivers.Six types of brakes, two types of frequency control, thirteen starting forces.Multiple protection: low voltage protection, throttle signal loss protection, over-temperature protection.Specification: Material: PCBOptions: 12A, 20A, 30AColor: Shown As PicturesWeight: 21 - 36gType: RC Model Part & AccesPackage List:1 * ESC1 * ManualNote:Instruction:1. Normal startup processPull the throttle lever to the lowest position; power on the remote control; power on; detects the lowest throttle signal, long voice 'beep-- '; detection battery voltage, continuously issued several short sound"beep-" , indicating the current lithium power node number 1" D 123 "start sound; pulled high throttle can be started.2. Set the throttle stroke (it is recommended to set the throttle stroke when the electric adjustment is combined with the new speed controller)Pull the throttle lever to the highest position to remote control electric; ESC is powered to detect the highest throttle signal, two sound"beep beep -" means that the gas peak has confirmed, and automatically save; and pull the throttle lever to the lowest in 2 seconds when the detected minimum throttle signal, long 'beep - "a test battery voltage, continuous several short" beep - "sound, says the current use of lithium electricity section number -" 1 2 3 D "starting the sound - pulled the throttle can be started.After the maximum throttle is confirmed, the throttle lever remains at the highest position for more than 2 seconds, then enter to the remote control programming mode.If the throttle lever is not in the lowest position or in the highest position after the remote control and the power switch is first energized, a continuous "beep-.beep-.." will be sounded.
