E-flite 10-Amp Pro Brushless ESC - Manual

Thank you for purchasing the E-flite ® 10-Amp Pro Brushless
ESC. This controller has been designed for use in radio control
aircraft and to support continuous currents of up to 10 amps
when using 2-3 cell Li-Po battery packs and up to four sub-
micro servos. Standard features include advance BEC and safe
power arming along with programmable features such as low
voltage cutoff, braking, timing, and throttle input range.
Features :
• Up to 10 amps continuous current with proper air flow
• Programmable motor braking
• Safe power-arm mode prevents accidental starts
• Programmable low voltage cut-off with settings for 2-cell Li-Po (6V),
3-cell Li-Po (9V) or 70% of battery starting voltage
• Programmable throttle input range (1.1ms-1.9ms or Auto Select)
• Soft start
• Auto motor shut down if signal is lost or there is interference
• Programmable timing—2 user selectable ranges for use with a large
variety of brushless motors
• Pre-wired connectors—JST on battery input and 2mm female gold
bullets on motor output leads

** Sub-Micro Servos tested 4 at a time include E-Flite S-60, and S-75, JR 241, and ParkZone 3W servo.
Some other brands of servos have significantly higher current draw. Digital sub-micro servos, micro, and
mini-servos have higher current draw, use the 'standard servos' column. Always be sure to position the ESC
for maximum airflow since cooling can significantly aid in the performance of the BEC.
Before first use, please refer to Chart A for BEC usage and input
voltage/cell count guidelines. You must follow these guidelines for safe
operation. If you are using four servos with higher current draw, or more
than four servos for a quad flap option (for example), you will need to
disable the BEC. If you wish to disable the BEC, you must remove the red
receiver wire lead and connector from the receiver lead housing, and then
insulate it properly to prevent shorting.
When operating with the BEC disabled, E-flite recommends the use of a
separate, high power, external, BEC (like the Ultimate BEC), or receiver
pack and switch using the following items to ensure trouble-free operation:
1. Expert 720mAh Ni-MH 4.8V receiver battery (EXRB100), or similar
2. Expert Standard Switch (EXRA050), or similar
PLEASE READ THESE INSTRUCTIONS
IN THEIR ENTIRETY BEFORE USE
Before you connect your ESC and begin flying, take a moment to look it
over. The input power side has a black (negative) and red (positive) wire
along with a female JST Connector. The motor side has three, 2mm female
gold bullet connectors.
The black and red wires with the female JST connector will connect to your
power battery. The red wire connects to the red wire on your battery pack,
the black wire to the black wire on your battery pack. If the wires are
reversed, the ESC may be damaged.
YOU MUST ENSURE THAT YOU CONNECT
THE BATTERY POLARITY PROPERLY TO PREVENT DAMAGE TO THE ESC.
Reversing polarity will void your warranty, so always double-check this
connection. You may need to solder a male JST Connector (EFLA242) to the
battery so it matches this speed control. The throttle lead connects to the
throttle channel on your radio receiver.
WARNING: For your safety, when checking the startup function of the ESC
or making programming changes, please remove the propeller to prevent any
potential injury. You should always treat the motor and propeller as live and
dangerous, remembering that it could start at any time, and keep any body parts,
clothing and tools clear of the propeller arc. NEVER LEAVE THE BATTERY
CONNECTED WHEN NOT FLYING THE AIRCRAFT AND ALWAYS REMOVE THE
BATTERY FROM THE MODEL BEFORE CHARGING AND WHEN FINISHED FLYING.
When flying in hot weather, we recommend checking on the condition
of the ESC, battery, and motor after each flight, and you may want to
consider letting the electronic components cool to near ambient tempera-
ture between flights.
We also recommend throttle management when running near maximum
levels of current draw. It is not recommended that you fly an entire flight
at full throttle. If this is done, it is possible to cause permanent damage
to your motor, battery, and ESC.
Using Your 10-Amp Pro 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 cut-off voltage setting every
time you plug the battery in by first emitting a low, long tone, to show
startup. You will then hear 2 (for 2-cell Li-Po) or 3 (for 3-cell Li-Po) medium
length, mid tones to indicate the cell count (or 7 beeps if 70% Smart Cut is
selected), helping you to confirm the setting before every flight.
Connecting the ESC to the Motor
The three wires from your motor connect to the three female gold bullet
connectors on the ESC. The order of connection to the motor is not
important; you can plug any motor wire into any connector. If, when you
test the system, 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.
The plastic case area next to the small BEC heat sink is designed to accept
Velcro® or 2-sided tape. Do not cover the heat sinks as this will greatly
reduce their effectiveness.
Mount the ESC with a combination of Velcro®, 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 in the flight pack to the controller and listen for the tones to
indicate voltage cut-off.
3. After the controller has indicated the cell count, you will here a series
of 3 medium length rising tones to indicate the controller is armed,
and ready to fly.
4. When you move the throttle stick upward, the motor will run. If you
continue to move the throttle stick upward to Full throttle (high
position), the motor will run faster. If you lower the throttle
stick below the start-up position, the motor will stop running.
5. Check servo motion as part of your preflight check. It is very important
you make sure linkages are free-moving with no binding.
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
1.6ms), and the controller will beep 1 time, this indicates menu item 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).
