11. How do I mount the IMU module and the N3 main controller toan airframe?
Mount the IMU module and main controller as close to the aircraft?s gravitational centeras 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,pointingin thesamedirection as the nose of the aircraft.
12. Where should I mount the compass?
Mount the compass on the airframe in a positionaway from metals andmagnetic materials, such astheairframeitselfand the motors. The compass pointermustbefacingthesamedirection as thenoseof the drone.
1. After updating theN3?s firmware, the LEDs aresolid red. How do I fix this?
A Red LED signal meansthat the main controller is locked following the firmware update.
Click the unlock button to unlock the flight controller in DJI Assistant 2.
2. What should I do if the main controller fails to connect to DJI Assistant 2?
a. Check if DJI Assistant 2 and the driverhave beeninstalled successfully;b. Check if you used the right port (youshould usethe USB port on the LED module);
c. Check if the main controller is poweredon;
d. Use a differentUSB cable or USB port onyour computer.
3. How do Iuse Intelligent Flight Modes when usinganS-BUS controller?
Currently, only Course Lock and Home Lock are available when using anS-BUScontroller. To usethesefunctions, you mustset a three-way switch on theS-BUS controller as the Intelligent Flight Mode switch, correspondingPower, Home Lock and Course Lock respectively.
4. How many flight modes does the N3 support?
The N3 supports fiveflight modes: P (Position), A (Attitude), G (Gentle), S (Sport) and M (Manual)
5. Whatarethe main differencesbetween P, A, G, Sand M modes asshown in DJI Assistant 2?
PMode: Precise positioning usingGPS andVision Positioning modules;
A Mode:Attitude stabilization only; no GPS positioning.However, the aircraft is still able to use Returnto Homeas long as there is sufficient GPS signal;
G Mode:Lower flight speed, suitable for beginner pilots;
S Mode:The aircraftfliesata maximumattitude angle of 45°;
MMode:The aircraft can fly at any attitude angle. For experienced pilots only.
6. In Sport Mode, whatistheN3?smaximumattitude angle?
7. In what instances will theN3 automatically shut down the aircraft?s motors?
Thiswill occur in the following instances:
a. A motor is obstructedwhen flyingnear the ground.
b. Automatic take-off fails.
c. The drone falls and turnsonits sideafter taking off.
8. What can I do ifmy dronedoesn?ttake off after I pulldown the control sticks onthe controller?
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 thatall ESCs are functioningproperly, and thatthey are compatible with the N3.
9. Why did my droneturn overafter takeoff?
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 thatthe main controlleris facingthedirectiondisplayedinDJI Assistant 2;
b. Check thatthe IMU module is facing thedirectiondisplayedin DJI Assistant 2;
c. Check that thecompasspointis facingthe same direction as the noseof the aircraft;
d. Make sure that each propeller is matched withamotorwith the same rotational direction;
e. Check thattheESC signal cable matches the main controller cable;
f. Check thatthe drone is compatible with the N3.
10. How do Iperform amulti-side IMU calibration?a. You can detachthe IMU module and calibrateit by itself, or calibrate itwhile mounted onthe drone; b. If the IMU units are mounted on the aircraft, prepare by placingthe aircraft on the ground or up against a wallso that it standsupright; c. We recommend that you calibratetheIMU by following the LEDindicationsinstead 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 thedrone.
11. Will theN3automatically change to Attitude mode if the compass experiences magnetic interference?
The N3?s embeddedsoftwarewill self-correct when encountering problems caused by weakinterference. However, wheninterference is strong enough to induce significant course deviations and the compass is not able to calculate the drone?s course precisely,theN3 will automatically change to Attitude mode.
12. My drone is flying off-course andis unable tohoverpreciselyin P Mode.When hovering, it just circles around the positioning point.Whyis this happening?
The compass isprobably notmounted correctly. Remount it and make sure thatthe compass pointfaces thesame direction as thenose of the aircraft and re-calibrate it before use.
13. How do I resolve unexpected height dropswhen hovering withtheN3?
When hovering, heightdropsmayoccurif 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 gettingin.
Miscellaneous1. Does the N3 offer fault-tolerant control?
Yes, but only under thefollowing conditions:
a. Thrust-to-weight ratio (=thrust/weight) greater than 2.5;
b. The dronehas sixrotors or more;
c. Falling propellers are not contiguous;
d. If the propeller systemfailsand the aircraft beginsspinning, the N3automaticallyentersCourse Lock mode.2. Can a drone take off withoutthe N3 GPS module?
No.3. Is the N3 compatible with the Matrice 600?
Yes.4. Is the N3 main controller compatible with DJI SDK?
Yes, it supports DJI Mobile and Onboard SDK.5. What, if any,are therequirementsfor adrone?s motor axis distance when usedwith the N3?
There is no requiredaxis distance. However, if the aircraft generates a high level of vibrations we recommend that you use the A3 rather than the N3. We also stronglysuggest maintainingathrust-to-weight ratio (=thrust/weight) between 2to 4.6. What does it mean when theLEDs start flashingyellowthree timesin sequence?
If this happens, something was incorrectly setup and DJI GOwill help you troubleshoot the problem. There areusuallyfour main reasons for an incorrect setup:a. The motors weremounted asymmetrically or inthewrong direction,or the propellers have beenincorrectly paired with themotors. You can removethe propellers and mountthemagain. b. The drone?s gravitational center is not in its geometric center. In this situation, you can manually adjust the gravitational center until it overlapswiththe geometric center. c. Too much shake isgenerated by the airframe. d. The ratio of hover thrustto total propulsion is too low. Addmore payload to thedrone,or use a lower-poweredpropulsion system.
