Setting the throttle for the 1
st
Time
This is a “one off” connection procedure. The following procedure is to teach the ESC the full throttle position and must be repeated if a
different transmitter or receiver is used with the ESC.
Turn on transmitter.
Set throttle on the transmitter to "Full Throttle".
Connect the flight pack to the ESC, the ESC will make a tone like “de…de”. This confirms that the full throttle position has been
registered by the ESC.
Return the throttle stick on the transmitter to "off" position as soon within 5 seconds of hearing the 2 beeps. The ESC will sound a long
beep to confirm that it has learnt the off position.
The ESC then will beep a number of times depending upon the number of LiPo cells it detects (2 beeps =2 cells, 3 beeps = 3 cells)
The ESC with then enter its self checking procedure. If it is normal, you will hear a “
♪
1 2 3” tune. The ESC is now ready to use.
If the ESC doesn’t detect the throttle signal, it will constantly “beep” without stopping.
Any fault in self-check, and the ESC will beep 20 times.
Disconnect battery from the ESC.
Normal Operating Procedure
Move the throttle stick to lowest/off position.
The ESC detects the off throttle signal, and will sound a long beep.
The ESC analyses the battery voltage and will sound several short “beeps” depending upon the number of LiPo cells it detects (2
beeps =2 cells, 3 beeps = 3 cells)
The ESC with then enter its self checking procedure. If it is normal, you will hear a “
♪
1 2 3” tune. The ESC is now ready to use.
If the ESC doesn’t detect the throttle signal, it will constantly “beep” without stopping.
Any fault in self-check, and the ESC will beep 20 times.
Fault Finding
Problem
Cause
Solution
The motor dose not respond to the throttle
and emits bleeps
1. Throttle range not configured.
2. Throttle dose not return to the lowest point.
3. There is no signal output from receiver.
1. Configure the throttle range.
2. Move the stick to the lowest/off position.
3. Check the receiver.
The motor rocks back and forth and doesn’t
rotate
1. Bad solder joint between motor and ESC
2. Broken wire between motor and ESC
1. Check and re-solder connectors/joints
2. Check and repair any broken wires
The motor not respond to the throttle and emit
tone like “bee… bee,bee… ..de… de… de…
Throttle channels reverse
Reverse the throttle channel of your
transmitter (refer to the transmitter users
manual)
The motor not respond to the throttle and no
any tone is heard.
Battery connection error
Check the connection to the battery pack
and/or check battery voltage.
The motor suddenly stops while working
1. Loss of throttle signal.
2. Battery connection is loose.
1. Check the transmitter and receiver. Check
the connection to throttle channel.
2. Check the battery output and connection to
the ESC.
The motor rotates in the wrong direction
Incorrect phase sequence.
Swap the connection of any 2 of the 3 wires
between the ESC and the motor.
Full power not available or the motor stops
just after starting.
1. Throttle range not configured.
2. Not enough voltage in the battery.
3. Loose battery connection.
1. Configure the throttle range.
2. Recharge or replace the battery for a fully
charged one.
3. Check the connections between the battery
and the ESC.
