l Two way communication while connecting it with computer.
l Firmware can be upgraded by user.
l Motor wire can be checked while Connecting the power battery.
l Simply set function value by Prog-Box or by PC via USB link wire.
l Li-MH/Li-Po,Ne-Cd/Ne-mH,LiFe battery can be use.
l Enables setting the voltage per cell for the point at which the
controller’s cut off circuitry engages.Li-MH/Li-Po from
2.0-3.6V,Ne-Cd/Ne-.4-1.0V,LiFe from2.2-2.8V
l Reverse function. the delay time of reverse is adjustable.
l The power of the motor forward/ reverse can be set.
l Automatically detection the throttle route or can be set a fixed
number by manual operation.
l Auto cut off the power within 3 seconds if no radio signs.
Timing setting may be adjusted (0°-30°) to suit the motor type.
