Recommend for
experience pilot only
Maintain the altitude best above 3 meters
Flybarless stabilizing on ELEV and AILE direction is available for all control mode
After 10s when GPS signal lost,
System enters Atti. Mode. Automatically.
Only performing

Attitude & speed mixture control ensures
stability.
Enhanced fail-safe featured, auto hover or Go-Home if transmitter signal lost
Long and smooth flight route
High agility for all flying
Integrated tail gyro
The flying direction (YAW) of helicopter will be effected by cross
wind. Ace One system can detect the drifting angle & Speed, and
control the rudder servo to eliminate such influences.
In the case of flying forward in cross-wind, Tail Gyro can work on
two different modes as the example shown.

DJI Ace One is an autopilot system for radio-controlled helicopters, which completely takes the stress out of flying RC helicopters for
both professional and hobby applications. Ace One can be installed in a variety of models, from small electric helicopters to large
gasoline and turbine helicopters.
Multiple control mode based on autopilot system:
Built-in functions include:
Flybarless rotor head support
Integrated engine governor for internal combustion engines
Tilt and roll gimbal stabilization

Package Contents
Main Controller (MC)
The Main Controller is the brain of Ace One. The MC communicates with the IMU,
GPS/Compass, engine governor, servos and RC transmitter to carry out autopilot
functionality. The MC provides a “black box” flight log, and USB interface to read flight logs,
configure Ace One and update firmware from a PC.
(System requirement: Windows XP SP3 or Windows 7)
GPS & Compass module (GPS)
The GPS/Compass module includes two status-indicating
LEDs. It should be installed on the tail boom, where there is a
clear view of the sky.
×1
IMU
The Inertial Measurement Unit (IMU) consists of one 3-axis
accelerometer, one 3-axis gyroscope and a barometer.
×1
GPS Tail Boom Mount
The GPS Tail Boom Mount and double-sided foam tape enable
secured installation for the GPS/Compass module on almost
any helicopters.
×1
3-PIN Servo Cable
Cables used to connect the MC to the RC receiver.
×10
3M 5925 Double Sided Tape
(Only for GPS & Compass module)
×4
Micro USB Cable
This cable is used to configure Ace One, update firmware and
download flight logs.

Quick Start Guide
For experienced users, the quick start manual provides
summary of the steps which can be found in detail in this
manual.
Warranty Card
Ace One comes with a two-year warranty, as described on this
card. Please keep this for your personal records.

Mounting and Connection
Where? The IMU is best positioned near the helicopter’s center of gravity, where
vibration is relatively low.
What orientation? Orient the IMU such that the arrow marked on the above
surface of the IMU faces the sky and points directly forward, backward, left or
right. The sides of the IMU should be precisely parallel to the helicopter body.
DO NOT MOUNT THE IMU UPSIDE-DOWN.
How? Use double-sided foam tape for secured installation.
1
Check the double-sided foam tape or Velcro regularly to ensure that the
IMU is securely positioned.
2
DO NOT cover the ventilation holes, keep them unobstructed.
3
The IMU module is NOT water-proof or oil-proof.
GPS & Compass Module (GPS)
Where? Mount it on the tail boom, between the
rotor-head and the tail-rotor. The compass is
sensitive to magnetic interference, so position the
module at least 20 cm from servos and 30 cm from
electric motors or gasoline (petrol) engines. The
GPS is sensitive to vibration interference, so position
the module at least 10 cm from the tail rotor. The
GPS should not be close to the main rotor head
because rotor blades can interfere with GPS satellite
signal, the farther from the center of the rotor disk,
the better.
What Orientation? The DJI logo marked on the
GPS should face the sky, with the orientation arrow
pointing directly forward. The GPS is packaged with
a special indication line for mounting for the first
time. The LED status indicators should face the tail
rotor.
1
If you are uncertain whether materials near the GPS are magnetic or not, you can use a compass or magnet to check it.
2
GPS mounting-support hardware is included in the Ace One package. If however you prefer to use your own GPS mount,
please make sure that the mount material is NOT magnetic.
Where? There is no orientation requirement for the MC. Maintain at least a 20-centimeter-distance between the MC and the
engine or motor. Choose a mounting location where as shorter servo extension wires are needed as possible. This helps reduce
the risks of electronic interference. Please also make sure the USB port is accessible when installing the MC so as to facilitate
software configuration.
After choosing a location to mount the MC, it is recommended that you DO NOT mount the MC until all wirings and software
configurations are completed.
A1 Before you Begin
Fly the helicopter without Ace One and make sure that the helicopter works properly without any autopilot assistance. To complete this
step, you will need a tail gyro instead of Ace One system. This is a good time to isolate and resolve unwanted vibrations. IT IS
IMPORTANT THAT YOU SHOULD NOT SKIP THIS STEP.

CAN Bus– Interface for Ace One Module
The Ace One MC uses CAN-Bus to power and communicate with
other Ace One modules. Three connection ports are provided: two
on the MC and one in-line connection on the GPS/Compass wire.
Ace One identifies the connected devices automatically without
configuration.
GPS module can be connected to either port of MC.
IMU can be connected to the MC or to the in-line port on the
GPS wire. Connect the GPS/Compass and IMU to the MC.

Receiver & Servos
STEP1: Set the transmitter to single-servo CCPM (Futaba: H-1; JR/Spectrum: 1sNORM; Hitec: 1-Servo 90°).
Connect the receiver to the MC input servo ports. (High voltage receiver is essential,over 7.4v)

The power consumption of Ace One is 5W maximum (testing condition: 0.9A@5V). For some small scale helicopters, the
BEC provided may not be able to supply enough overall power consumption, please use high performance BEC.
Battery or BEC
Ace One uses the same power source as the servos and receiver; power to all electronics connected to the MC can be supplied by
either servo input or output ports on the MC. Ace One operates with a power source between 4.8 to 8.4 volts DC. When choosing a
power source, bear in mind that all servos and Ace One will use that same power source, thus please make sure the power source you
use will also satisfy the servo requirements. A high capacity battery of 4000mAh or above is strongly advised, especially for large scale
electric powered helicopter.
