The motor will emit a
long beep to indicate the
system is ready to go.
Move the throttle
stick to the bottom
position after you
hear those two
beeps, the minimum
throttle position will
be accepted 1
second later.

Thank you for purchasing this HOBBYWING product! Please read this declaration carefully before use, once you starts to use, we
will assume that you have read and agreed with all the content. Brushless power systems can be very dangerous and any improper
use may cause personal injury and damage to the product and related devices, so please strictly follow the instruction during
installation and use . Because we have no control over the use, installation, or maintenance of this product, no liability may be
assumed for any damages or losses resulting from the use of the product. We do not assume responsibility for any losses caused
by unauthorized modifications to our product. Besides, we have the right to modify our product design, appearance, features and
usage requirements without notification. We, HOBBYWING, are only responsible for our product cost and nothing else as result of
using our product. Regarding the possible semantic different between two different versions of declaration, for users in mainland
China, please take the Chinese version as standard; for users in other regions, please take the English version as standard.
02 Warnings
Read through the manuals of all power devices and aircraft and ensure the power configuration is rational before using this unit, as
improper power configuration will overload the motor and damage the unit.
When installing this unit, relevant operations like soldering, connecting will be needed, so please ensure all wires and connections are
well insulated before connecting the unit to related devices, as short circuit will damage the unit. When soldering relevant wires of the unit,
please use a soldering iron with sufficient power to do the soldering, as poor connection may cause your aircraft to lose control or other
unpredictable issues like damage to the device.
Always keep your aircraft away from unsafe elements like obstacles, crowd, high-voltage power lines. Please fly your aircraft in the
working environment as regulated in this manual. Although there are some protections, improper use may still cause permanent damage
to the product.
Always disconnect and remove batteries after use, as the ESC may drive the motor to rotate and cause unpredictable danger if it`s still
connected to the battery. Long-time contact will cause the battery to completely discharge and result in damage to the battery or/and the
ESC. This will not be covered under warranty.
03 Features
High performance 32-bit microprocessor with the running frequency of up to 72MHz for excellent performance. The microprocessor
powered by the separate voltage-regulating IC, which features great anti-interference performance, greatly reduces the possibility of
losing control.
Separate switch-mode voltage-regulating BEC with adjustable voltage of 6V/7.4V and continuous/peak current of 3A/7A. The BEC is
separated from other circuits, its normal output will be guaranteed to protect your aircraft from crash when issues like the power board of
the ESC is burnt occur.
DEO (Driving Efficiency Optimization) technology or Freewheeling for smoother throttle response, higher driving efficiency and lower
ESC temperature.
Four flight modes: Fixed-wing, Helicopter (External Governor), Helicopter (Elf Governor), and Helicopter (Store Governor).
Soft start-up in the three Helicopter modes.
Helicopter speed-governing function, which features adjustable “Governor Parameter P/I”, is easy to use. It can guarantee the stable
rotation of main blades when the load changes dramatically.
Auto Restart Time allows you to interrupt the shutdown and landing during the preset time and restart the motor promptly to avoid crash
caused by improper operation.
Data Logging can record the minimum voltage, the maximum temperature and the standardized RPM of the current flight and output the
running data of the ESC in real time (HOBBYWING WIFI Express module, HW Link mobile phone APP are needed).
RPM Signal Output port for outputting the electrical RPM of the motor (calculated in 2 poles) in real time.
Reverse Brake allows your aircraft to simulate the landing of a real aircraft. That is a reverse thrust will be generated when the propeller
rotates reversely to shorten the coasting distance and make the aircraft stop rapidly.
Separate programming port for connecting HOBBYWING LCD program box or WIFI Express module.
ESC programming, firmware upgrade, and data checking via HOBBYWING WIFI Express module, HW Link mobile phone APP allows
you to program your ESC, upgrade its firmware and check relevant data wirelessly (HOBBYWING WIFI Express module is needed).
Real-time data checking for checking the running data of your ESC in real time via HOBBYWING WIFI Express module, HW Link mobile
phone APP.
Online data checking, ESC programming, firmware upgrade are supported (HOBBYWING LCD program box & PC or WIFI Express
module & Smartphone are needed).
Multiple protections like start-up protection, ESC thermal protection, capacitor thermal protection, over-current protection, overload
protection, and throttle signal loss protection.

05 User Guide
I. Wiring
①Throttle Signal Cable (White/Red/Black): plug it into the TH throttle on the receiver or the corresponding channel on the Flybarless system.
About which channel you should plug it in, it depends on the receiver type and the Flybarless system type. The White wire is for transmitting
throttle signals, the Red & Black wires are connected to the output end of the internal BEC in parallel (that is they are BEC output wire and
ground wire).
②RPM Signal Wire (Yellow): plug it into the RMP input channel on the Flybarless system. (This wire can be used for providing RMP signal
input when using external device for speed-governing.)
II. Normal Start-up Process
III. ESC/Radio Calibration
Notes:
1) The throttle range of the ESC is from 1100µs to 1940µs by default. You need to re-calibrate the throttle range when the first time
you use this ESC or after you change the transmitter.
2) During the ESC/Radio calibration, please set the throttle curve to NORMAL and ensure the corresponding throttle amounts to the
maximum throttle endpoint and the minimum throttle endpoint on your transmitter are respectively 100% and 0%.
06 ESC Programming & Data Checking
Attention:
1) The parameters of this ESC are programmable, you can adjust relevant parameter settings to meet different flight demands.
2) The ESC will record relevant data like the standardized speed (it can only be checked and won’t disappear when the ESC is
disconnected from the pack in “Helicopter (Store Governor)” mode ), the minimum voltage, and the maximum temperature of the
current flight. Therefore, if you want to check the relevant data after the flight, please keep the ESC connected to the pack and then
connect the LCD program box or WIFI Express module to the ESC to check the data. Those data won’t be stored after the pack is
disconnected from the ESC.
I. Program Your ESC with a Multifunction LCD Program Box
1. Wiring
The motor will emit several
short beeps to indicate the
number of LiPo cells
you’ve plugged in.
Turn on the transmitter,
and then move the
throttle stick to the
bottom position.
After connecting the ESC
to a battery, the motor will
emit “♪ 123” to indicate it’s
powered on normally.
5 seconds later,
the motor will beep
two short beeps to
indicate the
maximum throttle
position is
accepted.
Turn on the
transmitter
and move
the throttle
stick to the
top
position.
Connect a
battery to the
