Main functions:
1. Start up mode: it is possible to set two start up mode, Soft start up and Hard start up

2. Timing mode: Soft timing – for 2, 4, 6 pole brushless motors, Hard timing – for 6 and
more pole motors
3. Temperature protection: the controllers have automatic reduce output power with auto
detection for temperature (120°C)
Note: The controllers are supplied with soft start up and soft timing mode.
Operating instructions:
-Normal start up:
Connect the controller and motor as above connection drawing. Switch on the transmitter and
check the throttle stick is at low position. Connect the main power pack and switch on BEC (for
the controllers with BEC), you should hear a piece of music. After the music, you can begin
flying.
-Setting:
Connect controller with motor as above connection diagram. Switch on the transmitter and check
the throttle stick is at high position. Connect the main power pack and switch on BEC (for the
controllers with BEC). After a piece of music, you can begin programming. When choose one
setting, move the throttle stick from high to low position quickly. You should hear a ‘beep’, keep
the throttle stick at low position 5 seconds, then you should hear a piece of music. Now, you can
begin flying. For other settings, after a ‘beep’, move the throttle stick to high position quickly and
wait for the prompting music. Repeat the procedure.

Notice:
1. Choose suitable brushless motors and propellers, ensure the working current never exceed
specified current of ESC.
2. Make sure the connection for battery positive and negative is right. Reversing the connection
will damage the ESC permanently.
3. Use suitable batteries, do not exceed specified voltage of ESC.
4. Do not disassemble the ESC by self, it will damage the ESC or lose message.
5. The ESCs are designed for airplane models only.
6. Take care in using safely. Incorrect use may cause injury to the body. The company will not be
responsible for any damage or loss caused by incorrect operation.
7. Reverse the motor direction by exchanging the position of any two connections to the motor.
Warning:
The propellers on turning are dangerous. Disconnect the main power pack immediately
after flying.
