(3) Remote Control Receiver Wiring
Prepare a PWM receiver with at least 5 channels and corresponding RemoteControl.

The RemoteController should be set to the Fixed-Wing mode.

NOTE: For the V-tail and flying wing the flight controller will automatically mix controls
without the need for remote control settings.

NOTE: No matter what type of aircraft you use five channels from the receiver must
always be connected, otherwise the self-test of the FlightController cannot pass when it
is powered on.

(4) Flight Controller Installation

---> Direction of Nose

The FlightController can only be mounted as described above, horizontally and the arrow must
be pointed to the nose!

From NB ONE Reviews

• the unit needs to be mounted perfectly leveled with the plane as you cannot offset any
differences (there is no menu).
• the gyro can not be mounted in other position (side,etc), the reason is the same as
above; it is highly advisable to mount the gyro as close as possible to the COG of the
plane
• you need to connect ALL the input channels coming from the receiver even if you DO
NOT USE THEM, otherwise the unit will not engage; if you do not need the rudder for
example just disconnect the servo from the output.
This is also valid for the NB ONE+ FlightController !! it!

Calibration of Neutral Point in RemoteControl

First storage of ZERO postions for the sticks

On the RemoteController put the Throttle to minimum (bottom), the other channels are in the
middle then switch the Flight Mode Switch six times quickly through all positions.

After calibrating the RemoteController users are NOT ADVISED to adjust the TRIM on the
RemoteController.

The Flight Controller will automatically balance the Flight when in one of the automatic modes.

1 The aileron will swing up and down twice after the RemoteController calibration is completed,
indicating a successful calibration.

2. Calibration is required every time the RemoteController is replaced or the TRIM on the
RemoteController is changed.

3. The motor may rotate when the the RemoteController is first calibrated or when the
Power is switched ON in the aircraft – ATTENTION INJURY

This is because the throttle travel may be to high with the factory calibration. Don't worry this
phenomenon will disappear after the sucessful calibration of the RemoteController.

NOTE
This procedure has to be repeated after the first flight in (2) Manual Mode with the
corrected Trim settings for level flight. (see Page 18 )

Special NOTE:
Please re-calibrate the RemoteController if the following situtations occur:
A) The aircraft is slow and uncontrolled after take-off
B) The plane tilts to one side after take-off
it!

C) When the return function is activated the aircraft does not climb.

From NB ONE Reviews

NOTE

Set your radio transmitter as a normal plane (Even if you are using the flight controller on a
flying wing). The FlightController will do all the required mixing according to the plane type you
select using the dip switches.

Once everything is connected, turn on the aircraft (remove your propellers when testing new
stuff!!!). The FlightController needs about 5 sec to boot and you should not move it or do
anything on your aircraft when booting is running.
Once you get the confirmation signal from the ESC then you can check your moving surfaces.

First step is changing the flight mode to (2) Manual Mode (LED Mode = OFF) and check if the
surfaces are moving to the right directions (If not then invert the channel on your transmitter).
After that switch to (1) Attitude Mode (equal to Stabilize for the Arduplane fellows) (LED Mode =
RED) and check if the surfaces are correcting on the right directions.
If not use the screw driver and move the corresponding adjusting pot to the other side (For
instance from A to B side) to reverse the direction of the servo correction (If you are not familiar
with flight controllers ask help to an experience fellow on your airfield).
The adjusting pot is also used to adjust the gains for each channel. I had good results putting
my pots at 1/4 from the top arrow.

For the NB ONE+

Change Direction of the Output:
Use the screwdriver and move the respective DIP Switch into the other direction.

(7) Servo Direction Setting – RemoteController
This is to check for the correct operation of the servos when in (2) Manual Mode

NOTE: Adjustment of servo direction has to be done in the RemoteController!

NOTE: Remove the Propeller for this test and make sure the throttle stick is in the
bottom position.

1. Switch Flight Mode Switch to (2) Manual Mode

2. Move the directional control sticks on the RemoteController in each end position and
check that the servos move in the correct direction.
Correct it on the RemoteController if the direction is wrong

3. The control boards can be manually and mechanically corrected so that their initial
positions are correct. ???

1. Switch Flight Mode to (1) Attitude / Altitude Mode

2. Swing the aircraft in all directions and observe the servo responses

1.) Roll DIP-SWITCH 3

Swing the aircraft around the roll direction and check for the ailerons to correct in the right
direction.
When rolling to the left the left aileron has to go down and the right has to go up!

2.) Pitch DIP-SWITCH 4

Move the aircraft nose up and down and check the elevator for correct direction
When the nose goes up the elevator must go down!

3.) Yaw DIP-SWITCH 5

Turn the aircraft around its vertical axis and check the rudder for correct direction.
When turned to the right the rudder should go to the left!

(9) Flight Modes

1) Fixed Height Mode – Attitude / Altitude Hold - Aquire Mode

This mode actually consists of 3 Modes. The first is the attitude hold mode which will keep the
aircraft in level flight. The second Mode is the Altitude hold Mode which assures a safe altitude
for flighing (35m). The third mode is the Altitude aquire Mode which allows for a semi-automatic
take-off as described below.

Flying mode suitable for novice and FPV enthusiasts

In this mode the aircraft will fly level after you release the Sticks on the RemoteControl

The Aircraft can flip freely and it will return to this mode when the control stick is back in the
middle position.

From NB ONE Reviews

The best mode to fly this unit; the gyro is doing a very good job in keeping the airplane level; I
didn't noticed any over correction or fluttering on the flying surfaces; the plane flew really
smooth for the size.

1. In this mode the aircraft should maintain an altitude of 35m.

2. The aircraft can take-off directly in this mode, it will climb to this altitude automatically,
which is very helpful.
3. In this mode the aircraft will maintain a minimum of 45% Throttle and the
FlightController will semi-automaticall control the Throttle thereby reducing the
possiblity of the aircraft to get out of control.

• The aircraft will enter a certain height within 1.5 seconds after the pitch Stick returns to
center position.
• Push the Throttle Stick to a high power position to provide higher power for the aircraft.

From NB ONE Reviews

it!

In this mode you are supposed to give 10% throttle and then the gyro will take over, full throttle
and take the airplane up to 35 meters height and keep it at that height while you are flying
around. Well that's in theory at least as in practice was a bit different...

2.) Manual Mode

The FlightController will not interfere with the signals from the RemoteControl / YOUR INPUTS

You have full control over the aircraft.

From NB ONE Reviews

Not too many details here, use this mode to trim the plane in the first flight; once trimmed, land
the plane and "teach" the gyro the new zero position of the sticks; in order to do that you will
need to move the "MODE" switch for 6 times quickly going through all three positions.
The FlightController will "acknowledge" the new settings by waving the ailerons twice.

3.) Fenced Mode (GPS)

In this mode the aircraft will fly within the selected radius, which is here called the fence, and be
fully stabilized.

If the border of this range is reached the aircraft will automatically return to its starting point and
start circling unless you move your control sticks, which will stop the return.

A) Understanding of electronic fence mode

On the FlightController you can set the radius of 100-300 meters of electronic fence
with the Poti “R”
With the GPS module installed and connected the fence mode is activated once the GPS
has logged on – RED LED is ON constantly.
When the aircraft reaches the set fence boundary, it will take the initiative to return.
It should be noted here that when starting the fence mode, the aircraft will not return
immediately, but must fly to the set distance to start the return automatically.

B) During the return flight, the throttle will be controlled by FlightController.

When the aircraft arrives at the take-off point, it will circle over the take-off point.
At this time, pulling the aileron or elevator will release the return circle. Therefore, during
the return flight, please do not pull the remote stick. Only when the aircraft reaches the
set point, should the aileron or elevator stick be moved.

C) With regard to one-click return flight, such as using Manual or Stabilized mode, flying
out of the fence radius, then switching the Fence Mode ON, the aircraft will return
immediately.

Outside the fence, all control of the aircraft is controlled by the FlightController.
When the aircraft enters the fence, the aileron or elevator can cancel the return flight.
it!

Keep in mind that the Fence Mode is not a key return to home, but lets the aircraft fly within the
set radius.

Only when the aircraft reaches the set radius position, it will start the automatic return flight.

Please do not move any RemoteController stick during the return flight.

1. Do well in installation and commissioning by referring to the instructions.

2. Understanding of electronic fence:

This flight controller can set the radius of 100-300 meters of electronic fence.
After carrying GPS module and starting the fence mode, when the aircraft flies to the
fence boundary, it will take the initiative to return. It should be noted here that when
starting the fence mode, the aircraft will not return immediately, but must fly to the set
distance to start the return automatically.

3. During the return flight, the throttle will be controlled by flight controller. When the aircraft
arrives at the take-off point, it will circle over the take-off point. At this time, pulling the
aileron or elevator will release the return circle. Therefore, during the return flight, please
do not pull the remote stick. Only when the aircraft reaches the set point, can the aileron
or elevator stick be pulled up.

4. With regard to one-click return flight, such as using manual or balanced mode, flying out
of the fence radius, then switching the fence mode, the aircraft will return immediately.
Outside the fence, all control of the aircraft is controlled by flight controller. When the
aircraft enters the fence, the aileron or elevator can cancel the return flight. Keep in mind
that the fence mode is not a key home, but let the aircraft fly within the set radius. Only
when the aircraft reaches the set radius position, it will start the automatic return flight.
Please do not move the remote pole during the return flight. Keep in mind.

5. Repeatedly check the control direction of gyroscope and the ground test of the remote
control direction (check the working direction of gyroscope first, then adjust the control
direction of remote controller).
When the remote controller handles the fence mode or the fixed height mode, the
green light flashes, pushes the throttle, the motor rotates rapidly, and the elevator goes
up. On the contrary, if the elevator goes down, it cannot take off (this step is very
important).

6. When using this flight controller for the first time, or replacing the receiver, GPS module
and other equipment, the position of remote control sticks must be calibrated (in some
cases, the motor will rotate, please note) if not calibrated, otherwise the flight controller
will not be able to work properly.
If the calibration is successful, the aileron will oscillate dramatically. Otherwise, please
repeat the calibration.

7. The flight controller can balance aileron, elevator and rudder at the same time.

8. In fencing mode, you can take off with one click. Push the throttle stick, and the plane will
take off on the ground and automatically rise to 35 meters.

9. On a new location for flight it takes about 2 minutes for the first GPS positioning, and the

second positioning is very fast. The lights on the GPS module are not the basis for
successful positioning.
Mainly depends on whether the red light of the flight controller is always on. In addition, if
d

the positioning is unsuccessful, the flight controller will not unlock. Only if the positioning
di

is successful, the aircraft can start.

Flight attention points:

1. refer to the instructions, do a good job of installation and commissioning.

2. repeatedly check the control direction of the gyroscope, and the direction of the joystick
control. (Check the working direction of the gyroscope first, then adjust the control
direction of the remote control) Ground test. When the remote control is in the fixed
height mode, the green light flashes quickly, the throttle is pushed, the motor rotates
rapidly, the elevator surface is lifted up, and the elevator is facing down. Can't take off
(this step is very important)

3. When using this flight control for the first time, or when replacing the receiver, etc., the
remote control lever position must first be calibrated. (In some cases, the motor will
rotate, please note) If it is not calibrated, the flight control will not work properly.

4. the flight control can balance the ailerons, lifts, and rudder surfaces at the same time.

5. in the high mode, you can take off with one button. (That is to push the throttle to the
pole, the plane will take off on the ground and automatically climb to a height of 35
meters)

6. in the new venue, the first GPS positioning, it takes about 2 minutes, the positioning is
very fast, the light on the GPS module is not used as the basis for positioning success,
mainly depends on whether the red light of the flight control is always on, in addition, the
