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.
Note: The recommended settings are set at the default
settings (see point #5, page 11).
30-Amp Pro Switch-Mode BEC Brushless
Controller
Your Bf-109G PNP comes out of the box with the E-flite
30-Amp Pro Switch-Mode BEC Brushless Controller. This
controller has been designed for use in radio control
aircraft and is designed to support motor currents up
to 30 amps continuous, and a 5-volt Switch-Mode BEC
circuit capable of 700mAh continuous current on any
recommended input voltage with a 3- to 4-cell Li-Po
battery. It is suitable to use with most radio brands.
If you intend to fly your Bf-109G PNP stock, then there
is no need to program your ESC. It comes installed with
the default settings. If you intend to re-program the ESC,
we strongly recommend removing the propeller first in
order to keep it from spinning if the motor is accidentally
engaged.
Note: ALWAYS assume the motor and the propeller
are live. ALWAYS keep clear of the propeller at all
times. The high rpm of the brushless motor can cause
severe injury.
Features
• Up to 30-amp continuous current with proper airflow,
35-amp peak
• 5-volt Switch-Mode BEC circuit capable of 700mAh
continuous current on any recommended input
voltage
• Drives up to 5 analog or 4 digital sub-micro servos
with the BEC
• 3S-4S Li-Po or 9- to 12-cell Ni-MH/Ni-Cd input voltage
• Programmable motor braking
• Safe power-arm mode prevents accidental starts
• Programmable low voltage cut-off with settings for 3S
Li-Po (9.2V), 4S Li-Po (12V) or 74% of battery starting
voltage
• Programmable soft start for helis and airplanes
• Auto motor shutdown if signal is lost or there is
interference
• Programmable timing has 5 user-selectable ranges
for use with a larger variety of brushless motors
• Heli mode for starting the motor with a low speed
ratio
• Optional RS232 Serial Link available for programming
(EFLARS232)
• Pre-wired connectors - E-flite EC3 connectors on
battery input and 3.5mm female gold bullets on
motor output leads
Using the 30-Amp Pro Switch-Mode BEC
Brushless Controller
This controller is very simple to use, and for safety, will
not arm the motor until the throttle stick has been held
in the Idle/Off position for more than 1 second. The
controller will indicate the soft cutoff voltage setting
every time you plug the battery in by first emitting a
low, long tone, to indicate startup. Depending on the
selected cutoff voltage (default is 74%), you will then
hear the respective number of medium length mid tones
to indicate the cell count or a musical tone for the 74%
cutoff, helping you to confirm the setting before every
flight. Proper air cooling is required during flights so
the ESC should be placed in an area where air flows over
the controller.
Connecting the ESC to the Motor
The three wires from the motor connect to the three
female gold bullet connectors on the ESC. The order of
connection to the motor is not important; any motor wire
can be plugged into any connector. If the motor runs
backwards, you can simply unplug and switch any two of
the motor wire plugs connected to the ESC.
Mounting the ESC
Choose a location that has good airflow and offers good
protection. Do not cover the side with the flat heat shield
with hook and loop or tape as this will greatly reduce its
effectiveness. Mount the ESC with a combination of hook
and loop, 2-sided foam tape, and/or tie wraps.
Starting Your Power System
1. Turn on your transmitter and ensure the position of
the throttle stick is set to Idle/Off.
2. Plug the battery pack into the controller. You will
hear 1 low long tone to indicate startup, then the
respective number of medium-length mid tones to
indicate the cell count or a musical tone for the 74%
cutoff, followed by 3 rising tones to indicate the
controller is armed.
