N3 Hardware Installation
IMU redundancy makes an entire flight system more reliable. IMU sensors are critical to the functioning of the flight controller so a failing IMU unit may cause unpredictable aircraft behavior. Redundancy means having a set of two IMUs, so in the unexpected event that one fails, the other will continue to function and ensure continued safe flight.
The upgraded N3 has an external IMU module which, combined with the dual IMU module inside the N3, creates a triple redundancy IMU system to significantly decrease the risk of IMU failure, increasing the reliability of the N3.
When upgraded via the A3 Upgrade Kit, the N3 will have a total of two consumer-grade IMUs and one industrial-grade IMU, and two industrial-grade GPS modules.
The A3 Pro has three industrial-grade IMUs and three industrial-grade GPS modules.
Yes, the N3 supports DJI Lightbridge 2, S-BUS and DJI DR16 receivers. Users who prefer either PPM or PWM receivers can change the port to S-BUS using a PWM adapter.
DJI Lightbridge 2, S-BUS and DJI DR16.
The N3 is compatible with all Zenmuse Z3/X3/X5/X5R cameras and Z15 GH4/BMPCC/A7/5DIII and Ronin-MX gimbals.
The N3 is compatible with all standard 400Hz ESCs with 1520us center points. However, only DJI ESCs are able to offer feedback on voltage, current and motor speed.
You can use the iESC port to connect the N3’s main controller to a DJI ESC for communication and upgrades. The communication function offers you ESC data, including motor speed, voltage and ESC error. The upgrade function updates the DJI ESCs firmware. With ESC adaptor cables you can connect up to 8 ESCs to the main controller.
Mount the IMU module and main controller as close to the aircraft’s gravitational center as possible. Keep away from other electronic devices, such as GPS modules, receivers, ESCs and motors. Make sure the IMU module is parallel to the airframe, pointing in the same direction as the nose of the aircraft.
Mount the compass on the airframe in a position away from metals and magnetic materials, such as the airframe itself and the motors. The compass pointer must be facing the same direction as the nose of the drone.
Software Settings
A Red LED signal means that the main controller is locked following the firmware update. Click the unlock button to unlock the flight controller in DJI Assistant 2.
a. Check if DJI Assistant 2 and the driver have been installed successfully;
b. Check if you used the right port (you should use the USB port on the LED module);
c. Check if the main controller is powered on;
d. Use a different USB cable or USB port on your computer.
Currently, only Course Lock and Home Lock are available when using an S-BUS controller. To use these functions, you must set a three-way switch on the S-BUS controller as the Intelligent Flight Mode switch, corresponding Power, Home Lock and Course Lock respectively.
The N3 supports five flight modes: P (Position), A (Attitude), G (Gentle), S (Sport) and M (Manual).
P Mode: Precise positioning using GPS and Vision Positioning modules;
A Mode: Attitude stabilization only; no GPS positioning. However, the aircraft is still able to use Return to Home as long as there is sufficient GPS signal;
G Mode: Lower flight speed, suitable for beginner pilots;
S Mode: The aircraft flies at a maximum attitude angle of 45°;
M Mode: The aircraft can fly at any attitude angle. For experienced pilots only.
This will occur in the following instances:
a. A motor is obstructed when flying near the ground.
b. Automatic take-off fails.
c. The drone falls and turns on its side after taking off.
a. Double-check that the remote controller is linked to your drone;
b. Connect the main controller to DJI Assistant 2 or DJI GO to troubleshoot and check its status. Follow the suggested steps to fix error(s);
c. Check that all ESCs are functioning properly, and that they are compatible with the N3.
If your drone turns over, it could be due to incorrect setup or configuration of the system. Complete the following steps to correct any faults in setup.
a. Check that the main controller is facing the direction displayed in DJI Assistant 2;
b. Check that the IMU module is facing the direction displayed in DJI Assistant 2;
c. Check that the compass point is facing the same direction as the nose of the aircraft;
d. Make sure that each propeller is matched with a motor with the same rotational direction;
e. Check that the ESC signal cable matches the main controller cable;
f. Check that the drone is compatible with the N3.
a. You can detach the IMU module and calibrate it by itself, or calibrate it while mounted on the drone;
b. If the IMU units are mounted on the aircraft, prepare by placing the aircraft on the ground or up against a wall so that it stands upright;
c. We recommend that you calibrate the IMU by following the LED indications instead of by connecting it to a computer. This allows you to move the drone around freely during calibration;
d. When calibration is completed, you will need to restart the drone.
The N3’s embedded software will self-correct when encountering problems caused by weak interference. However, when interference is strong enough to induce significant course deviations and the compass is not able to calculate the drone’s course precisely, the N3 will automatically change to Attitude mode.
The compass is probably not mounted correctly. Remount it and make sure that the compass point faces the same direction as the nose of the aircraft and re-calibrate it before use.
When hovering, height drops may occur if the barometer has been affected by external air flow. You can counter this in two ways:
a. Keep the flight controller (where the barometer is built-in) away from propellers.
b. Block all the ports of the flight controller with a sponge to stop air from getting in.
Yes, but only under the following conditions:
a. Thrust-to-weight ratio (=thrust/weight) greater than 2.5;
b. The drone has six rotors or more;
c. Failling propellers are not contiguous;
d. If the propeller system fails and the aircraft begins spinning, the N3 automatically enters Course Lock mode.
Yes, it supports DJI Mobile and Onboard SDK.
There is no required axis distance. However, if the aircraft generates a high level of vibrations we recommend that you use the A3 rather than the N3. We also strongly suggest maintaining a thrust-to-weight ratio (=thrust/weight) between 2 to 4.
If this happens, something was incorrectly setup and DJI GO will help you troubleshoot the problem. There are usually four main reasons for an incorrect setup:
a. The motors were mounted asymmetrically or in the wrong direction, or the propellers have been incorrectly paired with the motors. You can remove the propellers and mount them again.
b. The drone’s gravitational center is not in its geometric center. In this situation, you can manually adjust the gravitational center until it overlaps with the geometric center.
c. Too much shake is generated by the airframe.
d. The ratio of hover thrust to total propulsion is too low. Add more payload to the drone, or use a lower-powered propulsion system.
