DJI Ace One Introduction 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: GPS Cruise Mode Command Stick Meaning Atti.
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 ×1 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.
Mounting and Connection 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.
A3 Connections GPS/COMPASS: Mount to the Tail boom, 20 cm from servos, 30 cm from motor, 10 cm from tail rotor. LEDs are status indicators. In-line CAN-Bus Port: This CAN-Bus port can be used for the IMU connection or for future hardware upgrades. Micro-USB: PC connection for configuration and firmware upgrades. Battery MUST supply 4.8 - 8.4 volts. Could be connect to any of the spare I/O port.
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.

The micro-USB port is used for MC configuration and firmware upgrade 1 2 4 3 5 6 8 7 10 9 18 11 12 17 16 15 14 13 Please connect your MC to your internet enabled computer by the USB cable before you open the assistant software. You have to register at the first time you use the assistant software.
1 For safety reasons, during configuration and system setup, please disconnect the power supply for Electric motor. 2 Please do the following configurations in Manual Mode of the autopilot system. Steps Description Page Please measure the center-of-gravity (C.G.
Configuration Procedure B1 GPS & IMU Mounting STEP1: Select IMU Mounting orientation 90º Assistant Software - MOUNTING page Backward Right 90º STEP1 Forward Left STEP2 STEP2: Fill in the distance between IMU/GPS and the C.G. of helicopter in X, Y & Z axles, please measure the C.G. with following method: a) Adjust your helicopter, and make it balance on X and Y axle as shown below. Y Rotor Head X Balance on X Y b) The C.G. should be on the extended line of helicopter main shaft.
B2 Control Mode Switch 1 The transmitter you used must be Fail-Safe featured, which allows you to setup fixed outputs for all channels if the receiver loses signals, otherwise Ace One will not enable the Enhanced Fail-Safe. See Page 23 for details. 2 Working mode for your transmitter should be HELICOPTER. 3 All the channels in your transmitter should be working independently: NO CCPM, NO channel MIX，NO EXP.
B3 Flybarless When system is powered on, you must not move your helicopter or sticks on transmitter until the system initialization is finished (about 5 second). Once you changed the Flybarless to “ON”, the AILE and ELEV swash mix ratios in swashplate settings will be disabled, while [Direction Reverse] button will always be available for AILE and ELEV. After you have set the Flybarless to “ON”, you have to adjust your swashplate parameters before setting your Flybarless control parameters.
B4 Swashplate You should finish the setup for your swashplate in Manual Mode. STEP1: In Assistant Software, page-SWASHPLATE: TX You have to set the transmitter to single servo swash (Futaba: H-1; JR/Spektrum:1sNORM; STEP3 STEP2 Hitec: 1-Servo 90°), and Ace One will do the CCPM instead. STEP4 STEP2: Please make your selection according to your swashplate type. IMPORTANT STEP3: The swashplate can be rotated in 360°, with 1°step increase or decrease. Not required in most conditions.
B6 Tail Gyro When system is powered on, you must not move your helicopter or sticks on transmitter until the system initialization is finished (about 5 second). STEP1: Please properly set your rudder servo type before you connect your tail-gyro servo to it, otherwise your servo In Assistant Software, page-Tail Gyro: might be damaged due to incorrect servo type chosen. STEP3 STEP2: We have [LimitA] and [LimitB] (Range: -140 to +140), which represent end-points of the tail rotor pitch.
B7 Engine Governor STEP1: Before using Governor Control mode, fine tune your Gas/Nitro engine to good condition. Otherwise the In Assistant Software, page-ENGINE: performance would be negatively impacted. STEP2: Select the operation mode: STEP2 Select [TX Control] for electric motor; For Gas/Nitro engine, select [TX Control] first, and finish next step: set throttle servo working range. Then select [Governor Control].
B8 R/C Transmitter Calibration TX In Assistant Software, page-TX MONITOR: Totally 4 TX channels are required to be calibrate: STEP1. Click [START] button, and move all of the sticks throughout their complete range several times. STEP2. Click [FINISH] button when you finished above procedures. 1 You have to finish the throttle and pitch curve setting before calibration, here the end-point of transmitter sticks will be record.
B9 Very important, check them carefully! SYSTEM CHECK You have to run the system check in Assistant Software – SYSTEM CHECK for Ace One system to work properly: Controller Output Check 1 Switch to Non-Manual mode first. 2 Click [START] button, Ace One will drive the swashplate up and down, representing collective movement during flight. 3 Click [NEXT] button, Ace One will drive the swashplate forward and back, representing elevator movement during flight.
B10 Autopilot Base Parameters Gain In Assistant Software, page-Autopilot: Range: Front/back & Left/Right 40%～400%; Vertical 50%~250% If too large, you will find the helicopter oscillating in the corresponding direction (About 5~10Hz). If too small, the helicopter will likely to be hard to control. In GPS Atti.
B11 Camera Gimbal Control This function aims to auto balance the 2-D camera gimbal. Roll direction of the gimbal is fully automatic controlled by Ace One, Pitch direction is automatic controlled by Ace One with real-time manual adjustment support.
Flight C1 Digital Compass Calibration Why calibrate the compass? Calibration procedure: Ferromagnetic substances placed on helicopter or around its working environment will affect the reading of earth magnetic for digital compass, it also reduces the accuracy of the helicopter control, or even reads incorrect heading.
C2 MANUAL MODE Test Flight 1 When the system is powered on, DO NOT moves your helicopter or sticks on transmitter until the system initialization is finished (about 5 seconds). 2 Don’t switch to Atti. Mode, GPS Atti. Mode and GPS Cruise Mode during Manual Mode Test Flight. Go through this section first, and read about how to do Autopilot Test Flight on Page 24. 1 Fly the helicopter. Trim transmitter such that the helicopter hovers stably.
C3 Enhanced Fail-Safe Ace One can detect the fail safe output from your receiver, if you have pre-set fail safe output correctly. Once your helicopter lost signal from the transmitter, Enhanced Fail-Safe function will control the helicopter automatically and save it in most of the conditions. 1 The Enhanced Fail-Safe (Auto Hovering and Auto Go-Home) will not be activated, until you’ve correctly Pre-set Transmitter Command Stick Center Position.
C4 Autopilot Test Fight When system is powered on, you must not move your helicopter or sticks on transmitter until the system initialization is finished (about 5 second). Please read this section before you switched to Atti. Mode, GPS Atti. Mode and GPS Cruise Mode 1 in good condition; Make sure the GPS signal is good, without red LED STEP2: Make sure your batteries are fully charged for your blinking.
Should you find the helicopter does not track straight in forward flight, Actual flig you might try re-mounting GPS in an ht directio n θ offsetting angle as showed in right Objective flight direction GPS mounting direction figure. Θ in the figure is the offsetting angle.
