Step 7. Power up the transmitter.

Make sure the transmitter and receiver are paired up before connecting battery to ESC. Please refer

to your transmitter manual for pairing method.

Before plugging in the lipo battery to the ESC, turn the transmitter on first

with the throttle stick in the lowest position, THEN plug in battery, be careful

not to move the throttle stick upward until you are ready to fly. After flying,

remove lipo from the plane first THEN turn off the transmitter.

Step 8. Connect battery to ESC.

Before plugging the lipo into the ESC, be sure the transmitter throttle stick is in the lowest position.

And connect the battery to ESC, please note that the ESC has already been preset in factory. But

throttle range should be reset whenever a new transmitter is being used. Please refer to "Begin To

Use Your New ESC" in page 8 for resetting throttle range. Be careful of the spinning motor shaft.

Step 9. Unplug the baterry and mount propeller and spinner

First all, please disconnect the battery!
Dismantle the spinner by remove the two screws with phillips screwdriver.

Fit the propeller yoke to the motor shaft, and tighten the two hex screws (on the top and bottom).

Please note that there are two flat dents on the shaft to align the two hex screws. Only when they

are aligned, the propeller yoke is firmly tightened on the shaft.

Flat dent

Check for proper operation of the throttle, if it is reversed, change the direction of the throttle channel

in the transmitter. Proper operation is at low throttle stick position the motor is stopped, high throttle

stick position the motor is operating at full speed. Adjust all control surfaces (aileron, rudder, elevator)

to be centered and move in the correct direction when moving the transmitter sticks.

4.Low Voltage Protection Threshold(Cut-Off Threshold)：Low / Medium / High
1）For lithium battery, the battery cell number is calculated automatically. Low / medium

/ high cutoff voltage for each cell is: 2.85V/3.15V/3.3V. For example: For a 3S Lipo, when

“Medium” cutoff threshold is set, the cut-off voltage will be: 3.15*3=9.45V

2) For NiMH battery, low / medium / high cutoff voltages are 0%/50%/65% of the startup

voltage (i.e. the initial voltage of battery pack), and 0% means the low voltage cut-off

function is disabled. For example: For a 6 cells NiMH battery, fully charged voltage is

Begin To Use Your New ESC

IMPORTANT! Because different transmitter has different throttle range, please calibrate

throttle range before flying.

Throttle range setting: (Throttle range should be reset whenever a new transmitter is

being used)

Switch on the

transmitter,

move throttle

stick to the top

position

Connect battery

pack to the ESC,

and wait for about

2 seconds

The “Beep-Beep-” tone should be

emitted, means the top point of

throttle range has been confirmed

Move throttle stick to the bottom

position, several “beep-” tones should

be emitted to present the amount of

battery cells

A long “Beep-” tone should be

emitted, means the lowest point of

throttle range has been correctly

confirmed

1.44*6=8.64V, when “Medium” cut-off threshold is set, the cut-off voltage will be:

8.64*50%=4.32V。

5.Startup Mode：Normal /Soft /Super-Soft (300ms / 1.5s / 3s)

Normal mode is suitable for fixed-wing aircraft. Soft or Super-soft modes are suitable for

helicopters. The initial acceleration of the Soft and Super-Soft modes are slower, it takes

1.5 second for Soft startup or 3 seconds for Super-Soft startup from initial throttle advance

to full throttle. If the throttle is completely closed (throttle stick moved to bottom position)

and opened again (throttle stick moved to top position) within 3 seconds after the first

startup, the re-startup will be temporarily changed to normal mode to get rid of the chance

of a crash caused by slow throttle response. This special design is suitable for aerobatic

flight when quick throttle response is needed.

6. Timing：Low / Medium / High,( 3.75°/15°/26.25°)

Usually, low timing is suitable for most motors. To get higher speed, High timing value can

be chosen.

After power on, motor

Normal startup procedure:

Move throttle stick to bottom position
and then switch on transmitter.

Move throttle stick

upwards to go flying

Connect battery pack to ESC, special tone
like “ ” means power supply is OK

Several “beep-” tones should
be emitted to present the
amount of lithium battery cells

When self-test is finished, a

long “beep-----” tone should

be emitted

1. Start up failure protection: If the motor fails to start within 2 seconds of throttle application,

the ESC will cut-off the output power. In this case, the throttle stick MUST be moved to the

bottom again to restart the motor. (Such a situation happens in the following cases: The

connection between ESC and motor is not reliable, the propeller or the motor is blocked, the

gearbox is damaged, etc.)

2. Over-heat protection: When the temperature of the ESC is over about 110 Celsius

degrees, the ESC will reduce the output power.

3. Throttle signal loss protection: The ESC will reduce the output power if throttle signal is

lost for 1 second, further loss for 2 seconds will cause the output to be cut-off completely.
