Programming Menu 3 – Timing
The default setting is 15 degrees. As a general rule, lower pole count
motors use lower timing and higher pole count motors use higher timing.
Please refer to your motor instructions and specifications for an indication
of the number of poles.

Motor Poles – 2 to 4
Expected Performance – Good balance of power and efficiency
Motor Poles – 6 or more

STANDARD TIMING ADVANCE
Timing Degrees – 15 & 20
Motor Poles – 6 to 12
Expected Performance – Good balance of power and efficiency

Motor Poles – 14 or more
Expected Performance – Good balance of power and efficiency
1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and
the controller will beep 3 times, indicating you are now in Menu 3.
2. Move the throttle stick to full throttle (>1.7ms) position to make
changes to the Timing programming.
a. To select 5 Degrees – You will hear 1 short beep. Move
the throttle stick to center (between 1.4 and 1.6ms). The
controller will beep 2 times, indicating you have set the
program selection or leave in full throttle for 5 seconds to
advance to the next selection.
b. To select 10 Degrees – You will hear 2 short beeps.
Move the throttle stick to center (between 1.4 and
1.6ms). The controller will beep 2 times, indicating you
have set the program selection or leave in full throttle for
5 seconds to advance to the next selection.
c. To select 15 Degrees – You will hear 3 short beeps.
Move the throttle stick to center (between 1.4 and
1.6ms). The controller will beep 2 times, indicating you
have set the program selection or leave in full throttle for
5 seconds to advance to the next selection.
d. To select 20 Degrees – You will hear 4 short beeps.

5 seconds to advance to the next selection.
e. To select 25 Degrees – You will hear 5 short beeps.
Move the throttle stick to center (between 1.4 and
1.6ms). The controller will beep 2 times, indicating you
have set the program selection or leave in full throttle for
5 seconds to advance to the first selection again.
Programming Menu 4 – Throttle Input Range (PWM)
The default setting is 1.2ms to 1.8ms and should work with most radio
systems. This option allows for proper throttle input with many different
radio systems. However, some radios have a wider output range, and may
give a more linear response with the 1.1ms to 1.9ms range. If you feel
there is too much “dead” area in the stick movement near full throttle, try
adjusting the end points in your radio, or change to the wider input range.
Be aware that if these settings are not correct, it may be impossible to
arm the controller.
1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and
the controller will beep 4 times, indicating you are now in Menu 4.
2. Move the throttle stick to full throttle (>1.7ms) position to make
changes to the Throttle Input Range programming.
a. To select 1.2ms to 1.8ms – You will hear 1 short beep.
Move the throttle stick to center (between 1.4 and
1.6ms). The controller will beep 2 times, indicating you
have set the program selection or leave in full throttle for
5 seconds to advance to the next selection.
b. To select 1.1ms to 1.9ms – You will hear 2 short beeps.
Move the throttle stick to center (between 1.4 and
1.6ms). The controller will beep 2 times, indicating you
have set the program selection or leave in full throttle for
5 seconds to advance to the first selection again.
Programming Menu 5 – Start-Up Rate
The default setting is 0.25 seconds. The start-up rate is the time it takes
to reach maximum motor speed. Changing the setting to 1 second can be
useful with power-fragile gear boxes.
1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and
the controller will beep 5 times, indicating you are now in Menu 3.
2. Move the throttle stick to full throttle (>1.7ms) position to make
changes to the Start-up Rate programming.
a. To select .25 second – You will hear 1 short beep. Move
the throttle stick to center (between 1.4 and 1.6ms). The
controller will beep 2 times, indicating you have set the
program selection or leave in full throttle for 5 seconds to
advance to the next selection.
b. To select 1 second – You will hear 2 short beeps. Move
the throttle stick to center (between 1.4 and 1.6ms). The
controller will beep 2 times, indicating you have set the
program selection or leave in full throttle for 5 seconds to
advance to the first selection again.
Programming Menu 6 – PWM Switching Frequency
The default setting is 8kHz, which should be acceptable for most motors.
If you have a low or very low inductance motor and know you need to use
a higher PWM Frequency (refer to the manual included with the motor),
then you can change the setting. Otherwise, we recommend leaving the
default setting.
1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and
the controller will beep 6 times, indicating you are now in Menu 6.
2. Move the throttle stick to full throttle (>1.7ms) position to make
changes to the PWM Switching Frequency programming.
a. To select 8kHz PWM Frequency – You will hear 1 short beep.
Move the throttle stick to center (between 1.4 and 1.6ms).
The controller will beep 2 times, indicating you have set the
program selection or leave in full throttle for 5 seconds to
advance to the next selection.
b. To select 16kHz PWM Frequency – You will hear 2 short
beeps. Move the throttle stick to center (between 1.4 and
1.6ms). The controller will beep 2 times, indicating you
have set the program selection or leave in full throttle for 5
seconds to advance to the next selection.
c. To select 32kHz PWM Frequency – You will hear 3 short
beeps. Move the throttle stick to center (between 1.4 and
1.6ms). The controller will beep 2 times, indicating you
have set the program selection or leave in full throttle for 5
seconds to advance to the first selection again.
Programming Menu 7 – Operating Mode
The default setting is set to Normal (airplane) Mode, which is limited to
a start-up rate of 0.25 or 1 second. Alternatively, the Heli Mode can be
selected which reduces the start-up rate to 5-seconds for the first start-up
and any start-up after the motor/ESC has been stopped for more than 5
seconds. This helps to prevent damaging the motor, gears or any other
components from an abrupt start-up when none of the parts are moving.
Any time the motor/ESC has been stopped for less than 5 seconds in Heli
Mode, the start-up will be immediate. This allows power to be applied im-
mediately, such as when aborting an auto-rotation attempt or for any other
reason, to help prevent a crash. Remember, you must wait more than 5
seconds after stopping the motor/ESC in order for the 5 second start-up to
occur again.
1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and
the controller will beep 7 times, indicating you are now in Menu 7.
2. Move the throttle stick to full throttle (>1.7ms) position to make
changes to the Operating Mode programming.
a. To select Normal Mode – You will hear 1 short
beep. Move the throttle stick to center (between 1.4 and
1.6ms). The controller will beep 2 times, indicating you
have set the program selection or leave in full throttle for
5 seconds to advance to the next selection.
b. To select Heli Mode – You will hear 2
short beeps. Move the throttle stick to center (between
1.4 and 1.6ms). The controller will beep 2 times, indicating you
have set the program selection or leave in full throttle for 5 seconds
to advance to the first selection again.
