Using ESC

Normal Startup Procedure

Move throttle stick to the bottom position (full Off throttle) Switch on the transmitter Connect one cell

battery to ESC System detects the Min throttle signal, makes a long “beep” sound System detects battery

voltage and makes one short “beep-” sounds when self-test is finished

♪ 1 2 3

tone should be emitted

ready for start.

Set Throttle Range (Throttle range should be setup when a new transmitter is being used)

Push the throttle stick to the top position (full On throttle) switch on the transmitter Connect one cell

battery to ESC System detects the Max throttle signal, and makes two “beep-” sounds, which denotes that Max

throttle has been confirmed and saved Pull the throttle stick to the bottom position within 5 seconds( program

mode will be entered if you wait for 6 seconds

)

System detects the Min throttle signal, makes a long “beep-”

sound System detects battery voltage and makes one short “beep-” sounds when self-test is finished

tone should be emitted Ready for start.

If the system doesn’t detect the throttle signal, it will make “beep-” sounds continuously without

stopping.

Protection

A. Low voltage protection: When power voltage is lower than the cutoff threshold, ESC will reduce output

power or cut off. Read the ”Configurable parameter” for more information.

B. Throttle signal lost protection: The ESC will reduce output power to 20% if throttle signal lost for 1 second,

the output power will recover if signal is detected.

C. Over heat protection: when the temperature of ESC is over 110 ,the ESC will reduce output power, the min

output power can be reduced to 35%. The output power will raise after temperature gets low.

Configurable parameter with transmitter ．． 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 Advance Timing: 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.

Program example with transmitter Setting “Timing Mode”to “High”, i.e. value #3 in program item #2 1 ． Enter Program mode Push the throttle stick to the top position, switch on the transmitter, connect battery to the ESC; wait for 2 seconds, “beeb- beeb-”will be emitted, then wait for another 6 seconds, special tone “♪ i 3 i 3”will be heard, that means program mode is entered.
