Features
– Safe Power-on Function:When the power is turned on, the motor will not be started immediately regardless of the position of the throttle stick to avoid personal injury.
– Throttle Stroke Adjustment Function:Adapt to the difference of the throttle stroke of different remote controllers, and improve the linearity of throttle response.
– Program Setting Items (you can use the remote control throttle stick or LED parameter setting card to set)
Brake setting:no brake/with brake;
Battery type:Lithium battery / Ni-MH;
Low voltage protection mode:soft shutdown/hard shutdown;
Low voltage protection threshold:low/medium/high;
Start mode:normal/soft/super soft start;
Timing angle:low/medium/high;
Restore factory default values;
– Comprehensive Protection Function
Under-voltage protection:set by the user through the program, when the battery voltage is lower than the protection threshold, the ESC will automatically reduce the output power;
Over-voltage protection:The input voltage exceeds the input allowable range and will not be activated. It will automatically protect and emit a rapid ‘beep beep’ alarm sound;
Overheating protection:Built-in temperature detection circuit, the output power will be automatically reduced when the temperature of the ESC is too high.
