Introduction
Thank you for purchasing the E-flite ® 80-Amp Pro Switch-Mode BEC Brushless ESC. This is
a lightweight, high-quality, efficient sensorless brushless electronic 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 80 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 safe power arming along with advanced programmable
features such as low voltage cutoff, braking, timing, throttle input range, and more, making
this truly a ‘pro series’ speed control.
CAUTION: Product may become hot when in use.

(12V), 5-cell Li-Po (15V), 6-cell Li-Po (18V), or 74% of battery starting voltage
• Programmable throttle input range (1.1ms–1.9ms or 1.2ms–1.8ms)
• Programmable soft start-up rate - .25 second or 1 second
• Auto motor shut down if signal is lost or there is interference
• Programmable timing—5 user-selectable ranges–use with a large variety of brushless
motors
• Two operating modes–Airplane or Heli
• Pre-wired connectors—E-flite EC5 on battery input and 4.0mm female gold bullets on
motor output leads

Servo Ratings with BEC Enabled
Normal recommendation is the ESC drives up to 7 analog or 6 digital standard-sized servos
with the BEC on any recommended input voltage.
Some servo combinations we have tested in various models include:
• 7 JR ® MC35 (JSP20030) analog micro servos ,1 JR DS368 (JRPS368BB) digital micro
servo, 3 EFL 15-25 size retracts —EFL Habu 32
• 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, micro and sub-micro servos draw less current which may affect your
servo usage as shown in the examples above with different servo combinations
and electric retracts. 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 and electric
retracts used. Also, always be sure to position the ESC for maximum airflow since cooling
can significantly aid in the performance of the BEC. The ESC is rated for at least 2.5-Amp
continuous current and 4-Amp short bursts.
Before first use, please refer to “Servo Ratings with BEC Enabled” 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 may 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 1100mAh 4.8V Ni-MH receiver battery (JRPB4240), 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 EC5 Male Device
Connector. The motor side has three 12-gauge wires (blue, red, and black) with 4.0mm
female gold bullet connectors on the ends.
The black and red wires with the EC5 Device (DEV) Connector will connect to your power
battery. The red wire connects to the red wire on your battery 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 EC5 Battery (BATT) connector on the
battery so it matches the EC5 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.
WARNING: NEVER LEAVE THE BATTERY CONNECTED WHEN NOT FLYING
THE AIRCRAFT AND ALWAYS REMOVE THE BATTERY FROM THE MODEL BEFORE
CHARGING AND WHEN FINISHED FLYING.
