30-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 30 amps continuous current when using 3- to 4-series

LiPo battery packs. You can drive up to 5 analog or 4 digital sub-micro-

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.

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. 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

signiﬁcantly aid in the performance of the BEC.

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 5 analog sub-micro-sized servos,

more than 4 digital sub-micro-sized 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

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-iteEC3MaleDeviceConnector.Themotorsidehasthree

16-gauge wires (blue, red, and black) with 3.5mm female gold bullet

connectors 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

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

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

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. 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 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.

Starting Your Power System

1. Turn on your transmitter and ensure the position of the throttle stick is
