E-flite 60-Amp Pro Switch-Mode BEC Brushless ESC - Manual

60-Amp Pro Switch-Mode
BEC Brushless ESC Instructions
Thank you for purchasing the E-flite ® 60-Amp Pro Switch-Mode BEC
Brushless ESC. This is a high-quality, efficient sensorless brushless elec-
tronic speed control with an integrated switch-mode BEC. It can operate
without the need for a separate receiver battery to power your servos and
receivers, saving you weight and complication. It is capable of up to 60
amps continuous current when using 3- to 6-series Li-Po battery packs.
You can drive up to 7 analog or 6 digital standard-sized servos with the
BEC on any recommended input voltage. This ESC also features an ex-
posed, finned heat sink aluminum case with lightweight plastic endcaps.
Additional features include safe power arming along with advanced pro-
grammable features such as low voltage cutoff, braking, timing, throttle
input range, and more, making this truly a ‘pro series’ speed control.

Servo Ratings with BEC Enabled:
Drives up to 7 analog or 6 digital standard-sized servos with the BEC on
any recommended input voltage. This also includes up to 7 standard ana-
log or 5 standard digital and 1 retract servo, perfect for Hangar 9 60-sized
warbird conversions.
Some servo combinations we have tested in various models include:
• 6 JR 537 (JRPS537) analog standard servos—Hangar 9
Ultra Stick 40 ARF
• 5 JR DS811 (JRPS811)/JR DS821 (JRPS821) digital
standard servos—Seagull Harrier 46 3D
• 4 JR DS811 (JRPS811)/JR DS821 (JRPS821) digital
standard servos and 1 JR 791 (JRPS791) retract
servo—Hangar 9 60-sized warbirds
• 5 JR DS811 (JRPS811)/JR DS821 (JRPS821) digital standard
servos and 1 JR 791 (JRPS791) retract servo—Hangar 9
Spitfire 60
• 4 JR SPORT
™ MN48 (JSP20040) analog mini servos—
E-flite Diamante 25e ARF
• 4 JR DS3421 (JRPSDS3421) digital mini servos—E-flite
Eratix 3D 25e ARF
• 7 JR MC35 (JSP20030) analog micro servos and 1 JR
RT88 (JSP20080) retract servo—25-sized warbird
Some other brands and models of servos may have significantly higher
current draw. Digital servos and binding servos of any kind typically have
higher current draw. As a general rule, mini and micro servos draw less
current which may affect your servo usage as shown in the examples
above. We recommend the use of a Hangar 9 Servo and Receiver Current
Meter (HAN172), installed between the throttle lead of the ESC and
receiver, to confirm current draw of the actual servos used. Also, always
be sure to position the ESC for maximum airflow since cooling can signifi-
cantly aid in the performance of the BEC.
Before first use, please refer to “Servo Ratings with BEC Enables” notes for
BEC usage guidelines. You must follow these guidelines for safe operation.
If you are using more than 7 analog standard servos, more than 6 digital
standard servos, or servos with higher current draw than the BEC can
deliver, 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. JR 1650mAh 4.8V Ni-MH receiver battery (JRPB5000),
or similar
2. JR Switch Harness (JRPA003), 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 an E-flite EC3 Male Device Connector. The motor side has three
13-gauge wires (blue, red, and black) with 3.5mm female gold bullet con-
nectors on the ends.
The black and red wires with the EC3 Device (DEV) Connector will connect
to your power battery. The red wire connects to the red wire on your bat-
tery pack, the black wire connects 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. Use only a genuine E-flite EC3 Female Battery
(BATT) connector on the battery so it matches the EC3 Male Device (DEV)
connector on the 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 it could start at any time, and keep any body parts,
clothing and tools clear of the propeller arc. NEVER LEAVE THE BATTERY CON-
NECTED 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. 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 during extreme conditions. It is not
recommended 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 the 60-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 70%), you
will then hear the respective number of medium length mid tones to
indicate the cell count or a musical tone for the 70% cutoff, helping you
to confirm the setting before every flight.
