OSD (On Screen Display)

Please visit this link and view the manual for a complete explanation of 

the items that can be viewed on the OSD.

Be advised: Your NiederTron Quadcopter comes preconfigured. Any 

changes to these configurations could affect your flight. It is advised not 

to open your NiederTron Quadcopter to prevent any altercations.

Take Special note of the motor configuration:

If your quadcopter flips immediately after takeoff, that usually indicates 

that you have an opposite propeller per that motor configuration. 
Below is an example systems diagram for the frame pinout.

ImmersionRC telemetry downlink, compatible with antenna trackers, 

and the iTelemetry apps on smart-phones. 

(Positional, Uplink status, Battery status)
-The quadcopter utilizes a 32 Channel 5.8 Ghz Video Transmitter (TX). 

Simply look up the users manual for your chosen video receiver and 

pair the receive channel with the transmit channel in the photo above.
Flight Controller: The NiederTron line utilizes the DJI Naza avionics 

and GPS. The avionics support multiple types of platforms, but for 

your quadcopter, you will be utilizing the Quad X. Check DJI.com for 

the complete manual of the Naza V2. Key points from the Naza V2 

manual as pertains to the Niedertron line will be mentioned below. 

Again, this aircraft is preconfigured and changes are not recommended. 

If you choose to download the Naza V2 Software from DJI.com, it 

explains in detail how the avionics work. It is highly recommended that 

you do so prior to flight. In the software, you can perform a stick 

configuration and see your stick movement and have peace of mind 

prior to flight.

1. Please download the driver and the Assistant installation software in 

EXEformat fromwww.dji.com.

2. Switch on the transmitter and then power on your autopilot system.

3. Connect your autopilot system and PC via a Micro-USB cable.

4. Open the driver installation software and follow the instructions to 

complete installation.

5. Run the Assistant installation software and follow the instructions to 

complete installation.
The NiederTron line utilizes the DJI GPS in configuration with its 

avionics. The GPS must be pointed forward (Forward is where the cord 

come out of the puck{This is also noted in the DJI Naza V2 Software}).

The V2 and V3 have three flight modes: 

GPS- The onboard GPS is utilized for stabilization. For example, if a 

gust of wind were to blow me to the right a few feet, I would over back 

to my original location with the use of the GPS positioning. When the 

user changes locations where magnetic polarity may have changed, it is 

advised to do a compass calibration. Again visit DJI.com and view the 

assistant software to view how to do this. There are also many videos 

online that show this.

Attitude Mode: This mode does not utilize GPS but still has auto level 

capabilities. This mode is ideal for flying indoors as GPS is not reliable 

inside buildings.

Failsafe: The pilot can initiate a failsafe where the aircraft will either 

ascend or descend to 60 feet AGL (Above Ground Level) and return to 

the point of launch. That is why it is critical to take off in a clear area 

incase the aircraft will RTL (Return to Launch). This can only be 

accomplished if the aircraft takes off in GPS mode. The pilot can also 

switch back to GPS or Attitude mode at any time. While in Failsafe 

Mode, the aircraft will emit a very bright orange LED light that can be 

seen from the ground while LOS (Line of Sight) is maintained.

Any of the following mistakes will lead to a dangerous accident, double 

check all these items: 

(1) Rotation direction of motor is opposite

(2) Infirm connection between the motor and the ESC 

(3) Wrong or infirm installation of Main controller 

(4) Wrong or infirm connection between the main controller and ESC.

(5) Propeller installation mistake

(6) Magnetization of the compass

Make sure the following items are correct.

(1) Make sure you have assembled your multi-rotor correctly.

(2) Make sure you have done the configuration procedure correctly.
(3) Make sure all connections are in good condition.

(4) Make sure batteries are fully charged for your transmitter, autopilot 

system and all devices.
After power up, the aircraft will emit a series of LED light codes as it 

does its systems start check. The light sequence can be seen above. 

After the rapid green LED pulses, the aircraft will begin to search for a 

GPS signal if you are in GPS mode. The GPS signal LED sequence can 

be see above. The more green the better. Ideally, you want a solid 

green pulse, but one green one red, or one green and two red are fine.
Low Voltage: The aircraft is outfitted with multiple ways of alerting the 

pilot of low voltage. The balance plug on the batter can plug into an 

external low voltage alarm on the aircraft. This generally will go off 

first. The voltage can also be monitored on the FPV (First Person View) 

display. The DJI Naza V2 also has two built in low level protections. 

First, the aircraft will blink red rapidly as a first warning then it will 

slowly descend as a second level protection. These levels of protection 

can be configured in the Naza V2 Software.

The aircraft will also have a built in option to bring the aircraft back 

with out initiating a Failsafe. In Home Lock flying, the forward 

direction is the same as the direction from home point to multi-rotor. 

All the following requirements are met: 6 or more GPS satellites are 

found, in GPS ATTI. Mode, and the aircraft is further than 10m away 

from the home point.

 Normal flying Home Lock Flying
By now you should have browsed through the Naza Software and have 

an understanding of the flight modes and the OSD. Now we will discuss 

a preflight for a standard flight.

1. Choose a wide open area

2. Choose flat and level ground

3. Make sure all connections are secure (antennas and plugs)

4. Check for any loose bolts and that landing gear is secure

5. Make sure GPS is pointing forward

6. Power on the handheld TX first 

7. Power on aircraft and wait for it to go through its light sequence

8. Wait for the green GPS lights

9. Move your TX sticks in any of the following motions to start your 

propellers. If you are unsure of how to fly a quadcopter, it is 

recommended that you search for a simulation program to learn.
Now we will move on to the operation of the radio. All of the 

switches must be flipped up or else the radio will now initialize. You 

will get an error message if a switch is flipped down. This is done for 

safety.

of time watching these videos. This covers the DJI Data link radio. Practice linking up 

and be sure to take the propellers off first. First use the data link to talk to the quadcopter 

via the NAZA Assistant on the iPad so you know you can communicate to it via 

Bluetooth. Then open the DJI Ground Station App and you should be able to 

communicate with the quadcopter. This option is especially good if you want to take the 

pressure out of flying.)

Quick Tips

-Check the tightening of bolt and the propellers. 

-Ensure the propellers are on properly (Clockwise/Counter)

-Never operate indoors with the propellers on

-Never manually work on the machine with the propellers on

-If an item has an antenna, make sure it is attached. A missing antenna could destroy the 

item if the energy has no where to travel.

-Remember that all setting are pre configured, any changes will change the flight 

behavior. It is recommended to scroll through the radio and take pictures of the screens. 

If you have any concerns, then you should not operate your machine. The system can be 

hooked up however and the controls will reflect in the Flight Controller Assistant. 

Unwanted changes could affect the flight controls, as well as the pulse rate.

-Remember, you are responsible for the aircraft. The aircraft relies on GPS for accuracy. 

It is recommended to fly in wide open areas where a clear line of sight is guaranteed. 

Buildings, cloud coverage, etc, will depreciate the GPS strength. 

-Take off in a wide open area in the event of a Failsafe return to home.

-Never leave batteries charging while you are not nearby. Lipo batteries from time to 

time have been known to catch fire due to over charging.

******Remember, the radio has different models. Make sure you select the right model. 

Choosing the right model goes back to the signal weight- if the wrong model is chosen, it 

could result in a potential crash. If you are unsure of this concept, research PPM in RC 

Receivers.
