2、Specification

   · Input voltage: 2.8V -4.2V (support 1-2 lithium batteries)

   · Continue current: 3A

   · Burst current: 4A (within 10 seconds) 

   · BEC output: NO

   · Size( lengthX width X high): 11x13x8 mm

   · Weight: 0.7 g

3、Parameter

   1）．BrakeType: Off,Soft brake and Hard brake. default is Off (brake disable). Soft brake: less forceful and brake time is longer. Hard brake: 
        
        more forceful and brake time is shorter.

   2）．AdvanceT(Timing Mode): Low, Middle and High, default is Middle. Low advance timing is recommended for high inductance and low 

        KV motors. High advance timing is recommended for low inductance and high KV motors, e.g. high KV outrunner motors. For some high

        KV motors, if it shakes while rotating in high speed, the “High” timing mode is recommended.

   3）．Start: Fast, Soft and Very Soft. default is Very Soft. Fast start is recommended for low inductance and low start loading motors, Very 

        Soft start is recommended for high inductance and high start loading motors.

   4）．OffType(Cutoff Mode,Low Voltage Protection Mode): Reduce power and Cutoff output power for selecting, default is Reduce the 

        output power gradually to 50% of the current power. 

   5）．Cutoff  threshold: 2.8V, 3.0V, 3.1V. default is 2.8V.
