3. When you move the throttle stick upward, the motor
will run. Continue to move the throttle stick upward
to the full throttle (high) position, and the motor will
run faster. When the throttle stick goes below the
start-up position, the motor will stop running.
4. Check servo motion as part of your preflight check.
It is very important to make sure linkages are free-
moving with no binding.
Remember, when in the programming mode:
Full Throttle = Stick Up
Idle = Stick Down
5. The default settings (from the package) for your
E-flite 30-Amp Pro ESC are as follows:
• Voltage cutoff set for 3S
• Open stock default is set to Brake Off, but
Brake On will be set to on for Bf-109G
• Timing set at 15 degrees
• Throttle Input Range set at 1.2ms to 1.8ms
• Start-up Rate (Acceleration Delay) set at 0.25
seconds
• PWM Frequency set at 8KHz
• Operating Mode set to normal (airplane)
Entering the Programming Mode
1. With the battery disconnected from the controller,
and the transmitter turned on, first move the throttle
stick to full throttle (>1.7ms) position. Leave it in
this position and then connect the battery to the
controller.
2. Wait for 5 seconds, and the ESC will give two
sets of fast ringing tones to indicate you have
successfully entered the programming mode.
3. Once you hear these tones, move the stick to center
(between 1.4 and 1.7ms) for 5 seconds, and the
controller will beep 1 time, indicating you are now in
Menu 1.
4. The controller will now wait 5 seconds for you to
make your selection; your programming options are
either full throttle (>1.7ms) or idle (<1.3ms).
5. When you have made a valid selection, the control
will beep once with a lower tone, and you can move
the stick back to center for the next menu item (2
beeps, 3 beeps and so on). If you do not make a
selection within 5 seconds, the controller will move
to the next menu item.

6. If you want to make changes in the programming
menus (see specific instructions below) move the
throttle stick to full throttle (>1.7ms) position. You
will have 5 seconds to make your selection.
7. If you want to advance to the next menu, allow the
programming to skip to the next menu after the 5
seconds have expired.
Programming Menu 1 – Voltage Cutoff
Use this option to set the voltage at which the controller
will shut down the motor to prevent damage to your
battery when it reaches the cutoff voltage. You will know
your battery pack has reached auto cutoff when you hear
the motor "pulse" repeatedly.
1. Move the throttle stick to full throttle (>1.7ms)
position to make changes to the voltage cutoff
programming.
a. To select 3-cell low voltage cutoff – 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.
b. To select 4-cell low voltage cutoff – You will hear
4 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 5-cell low voltage cutoff – 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 next selection.
d. To select 6-cell low voltage cutoff – You will hear
6 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.
e. To select 74% cutoff – You will hear 7 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.
IMPORTANT NOTE ABOUT 74% CUTOFF: This
option will activate the soft cutoff at 74% of startup
voltage or 9.2V, whichever is higher. For example,
if your pack measures 16.8 volts at startup, then
the soft cut will occur at 12.4 volts. The 74% cutoff
option will check the startup voltage every time you
plug the battery into the controller, so beware of
using partially charged packs, as the system cannot
protect your Li-Po batteries if you are using the 74%
cutoff and connect a partially charged pack. You will
know your battery pack has reached soft auto cutoff
when you hear the motor "pulse" repeatedly. We
recommend you land your model as soon as you
hear the motor pulse (indicating the pack voltage has
dropped to the cutoff voltage level) to prevent over-
discharge of the Li-Po battery pack, and to prevent
sudden power loss.
Programming Menu 2 – Brake Type
The default setting is Brake Off. This option gives you the
choice to have the ESC stop the propeller during flight
(Brake On) or allow it to windmill (Brake Off). Use the
Brake On options for folding propellers.
1. Move the stick to center (between 1.4 and 1.6ms)
for 5 seconds, and the controller will beep 2 times,
indicating you are now in Menu 2.
2. Move the throttle stick to full throttle (>1.7ms)
position to make changes to the Brake Type
programming.
a. To select No Brake/Brake Off – 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 Soft Brake – 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 Medium Brake – 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 Hard Brake – You will hear 4 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 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.
LowTimingAdvance
Timing Degrees – 5 & 10
Motor Poles – 2 to 4
Expected Performance – Good balance of power and
efficiency
Motor Poles – 6 or more
Expected Performance – Best efficiency and run time
(lowest power)
StandardTimingAdvance
Timing Degrees – 15 & 20
Motor Poles – 6 to 12
Expected Performance – Good balance of power and
efficiency
Motor Poles – 14 or more
Expected Performance – Best efficiency and run time
(lowest power)
HighTimingAdvance
Timing Degrees – 25
Motor Poles – 12
Expected Performance – Highest power, less
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.
