1. Introduction:
Arkbird Hummingbird is a compact flying wing FPV airplane. It is a BNF version airplane which is researched,
designed and produced by Arkbird FPV. This small plane is for novice and experienced users as well.
Features:
Dimensions: 860mm*420mm*10mm. It can be easily carried in your bag.
The airplane can continuously fly over 45 minutes. The flight speed can range between 45-80km/h.
With the onboard Arkbird lite autopilot, you can operate all the functions of Arkbird 2.0.
The optimized autopilot support Balance, Fence, Waypoint, Launch Assist, RTH, Cruise way point, Gyro
Mode etc.
Integrated Arkbird 433UHF receiver.
5.8G 500MW Transmitter. Transmission distance can reach to 1.5km with stable signal. If matching with
Arkbird 5.8G directional panel antenna or Arkbird mini AAT, the transmission distance can reach up to 5km.
The EPP material is applied to the whole body of the airplane. Carbon fiber material is also added for
strengthen in the process of producing. It is not easy to break in a crash due to its high anti-impact strength.

1. Ensure no accessories are short according to the package list.
2. Locate the fuselage and a pair of wings and winglets;
a) Screw off the screws and open the electronics hatch;
b) Route the servo lines through the hole of the fuselage (see picture below);
c) Servo lines should be connected to the ports on both sides. Beware the brown line should be connected to
negative port;
d) Glue the wings to both sides of the fuselage. Beware the wings should be aligned with the edge. Pins or
toothpicks are recommended to align them;
e) Glue winglets. Beware they should be aligned with the edge. The front surface should not be glued. Pins
or toothpicks are recommended to align them.

Step 3: Powered on test
1) Install antenna 5.8G to transmitter;
2) Get the battery;

7
3) Power on. Beware the plug is xt30 and there is a difference between position and negative pole;
4) After powering on the motor then check its condition:
The motor will continuously beep;
Power LED of transmitter (blue) will be constant on;
LED of GPS (blue) will be constant on;
The LED (yellow) of 433 receiver in the cabin will slowly or fast flash;
If the monitor and 5.8G receiver has been matched already, at first, the frequency of the transmitter and the receiver should
be the same. And then, connecting the monitor and receiver.
Upon they are connected, the OSD will display following parameters:
If GPS has been installed, the motor will slowly beep every 1 second.
Or if the GPS has not been installed, the OSD will display parameters as follows:
*Please ensure that all data about monitor, autopilot, transmitter and 433 receiver is reasonably correct. Then power
off the airplane.
Step 4: Prepare PWM of 433 UHF
1. The wire connection of 433 transmitter (sold separately) and radio receiver
The 433 transmitter is a separated part of the 433 system, and should be purchased. Please make sure that CH5 and
CH6 can be controlled by at least two or more switches on your radio. Please see the following picture:

8
As per the photo: As per the chart:
1 Balancing head of 3s battery; 1). Beware negative pole and positive pole of the battery 12v+ and 12v-
2 Receiver of radio for the power supply of the 433 transmitter;
3 3s battery; 2). Beware negative pole and positive pole of the output portal of
4 Arkbird 433 transmitter transmitter 5v+ and 5v- for the power supply of the radio receiver.
3). Channel mapping:
No.
433 transmitter
Receiver of radio (user supply)
1
CH1
For aileron (roll)
2
CH2
For going up and down (pitch)
3
CH3
For throttle (motor)
4
CH4
For direction (track)
5
CH5
For switches of 2/3 control flaps (excluding CH1-CH4)
6
CH6
For switches of 3 control flaps (excluding CH1-CH5)
4). Please make sure that each part is connected correctly before powering on.
If the 433 transmitter works well, the LED (yellow) will flash fast. If the 433 transmitter does
not receive signal from receiver of radio, the same light will flash slowly.
2. Binding the 433 System.
Power off the 433 transmitter, then power on airplane;
Constantly press the button (as per the photo) for about 6-10 seconds till the LED light flashes 1 time
every second;
Power on 433 transmitter, then LED will fast flash ;
Binding is finished;

9
Step 5: Final check
1. Check voltage of the batteries and ensure they are not excessively discharged. The lowest voltage of batteries
for airplane should not be lower than 9.6v. Otherwise, battery cells are likely to be damaged.
2. Make sure the inner part of the airplane is clear;
3. Testing the airplane
Step 1: Preparation
Before proceeding the next steps, please ensure the 433 transmitter and receiver are correctly connected and bound,
then:
1. Take off the propeller
To prevent yourself and bystanders from being hurt.
2. Plug off GPS
Otherwise the flight control will automatically search for satellites, which may cause failure of entering OSD.
All operations hereunder are done without GPS. It could be located as per the photo below:
Step 2: Requirement of radio
The functions of radio are varied from different brands. Please refer to relevant instructions on your radio’s manual.
1. Number of total channels should be equal to or over 6;
2. Create a new model on your radio.;
3. No mix mode, disable any mixing options.
4. One switch of 2 positions is needed. CH5 is the best port for it (as per aforesaid photo about wiring of 433
transmitter)
5. One switch of 3 positions is needed. CH6 is the best port for it (as per aforesaid photo about wiring of 433
transmitter)
6. Values of each channel should be equal to or over 100%. The value of channel for throttle should be -110%
or less.

10
Step 3: Choose one mode
Feel free to move the switches (as aforesaid). Beware the mode the AP is in, checking this icon on the OSD. The
mode will vary when you move ch5 and ch6 switches . Please remember the position which is important in the next
steps.
a. The flag in the red square stands for Manual Mode
b. The flag in the red square stands for Balance Mode;
c. The flag in the red square stands for Return to Home Mode;
Step 4: Check elevons movements
Keep the airplane in Balance Mode (the icon will be in the OSD). Then the airplane should be put in front of
your eyes as per the following photo (the head of airplane is facing you). The orientation of the elevons surface will
change while it is moved up and down, left and right.
1. Swing the airplane from right to left, elevon on the right side should face up, the one on the left side should
face down.
