Step 20 – Programming the E-flite 10A Pro Brushless ESC

The E-flite

10A Pro Brushless ESC 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.

The ESC has been preset for 2S Li-Po low voltage cutoff.

Features:

• Up to 10 amps continuous current with proper air

flow

• Programmable motor braking

• Safe power-arm mode prevents accidental starts

• Programmable low voltage cutoff with settings for

2-cell Li-Po (6V), 3-cell Li-Po (9V) or 70% of battery

starting voltage

• Programmable throttle input range

(1.1-1.9ms or Auto Select)

• Soft start

• Auto motor shutdown 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

Specifications:

• Continuous Current: 10A

• Max Burst Current: 12A (15 sec)

• Length: 30mm (1.2 in)

• Width: 17.5mm (.7 in)

•Height: 10mm (.4 in)

• Weight: 10 g (.35 oz)

• Cells: 2-3S Li-Po or 6-10 Ni-MH/Ni-Cd

• Battery Input Leads: 20 AWG with JST Connector

• Motor Output Leads: 20 AWG with 2mm Female

Gold Bullet Connectors

** 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 receiverpack 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 start-up
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 temperature
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.

Step 20 – Programming the E-flite 10A Pro Brushless ESC (continued)

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 cutoff voltage setting
every time you plug the battery in by first emitting a low,
long tone, to show start-up. 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 cutoff.

3. After the controller has indicated the cell count,

you will hear 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).

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. Please note that if you do not need to program

every menu item, you can simply exit the

programming mode after you have made the

required selections. You can do this by moving the

throttle stick straight to idle, after making your

selection, or leaving it in the idle position if you

made no selection (for approximately 8 seconds),

until you hear one set of 3 medium length rising

tones that indicate the controller has armed the

motor, or by simply unplugging the battery.

Remember, when in the programming mode:
Full Throttle = Stick Up
Idle = Stick Down

The default settings (from the package) for your E-flite
10-Amp Pro ESC are as follows:

• 3S (9V) auto cutoff for Li-Po

• Brake Off

• 4-pole and greater timing (outrunner or

6-pole motors)

• Throttle input range set to Auto Select Mode

(1.2ms–1.8ms)

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
that your battery pack has reached auto cutoff when you
hear the motor “pulse” repeatedly.

1. 3S Li-Po voltage cutoff – Full Throttle

2. 2S Li-Po or Ni-Cd/Ni-MH voltage cutoff – Idle

3. 70% Smart Cut soft cutoff (See below for Smart

Cut information)

NOTE: To access the 70% Smart Cut option, leave

the stick at full throttle for 7 seconds while in menu
