Thank you for purchasing Arkbird product. Before starting with the assembly of the VTOL plane, a few words
regarding the new firmware of Autopilot 2.0:
In vertical mode, newly developed settings are available to be customized including parameters adjustment,
unlock function and OSD interface instruction. Please refer to "Introduction to Upgraded Arkbird V1.3016" or the
latest upgrading files for more details. Please don't forget to install ESC with BEC or install another BEC 5v to
supply power for the servos, because the autopilot does not supply power for them.
The upgraded firmware (V1.3010) will have an option called "BimoFwing" that needs to be chosen to use
with Arkbird VTOL plane. The default control values are: 15, 12, 110.
In the BimoFwing option is set, the original "Manual Mode" will be replaced by "Hover Mode". This means that
the plane will entry into "Hover Mode" when you select "Manual Mode", then 5
following:
Return Home Mode
Hover Mode
Balance Mode.
The Autopilot will give you 1500us PWM output when entering the OSD menu. Please ddjust the servo 's midpoint when
display OSD menu.
The firmware V3.1010 has the option "Roll trim" in the CTL menu. In BimoFwing Mode, this option will adjust
the motor speed difference in VTOL mode. Please trim the value if the airplane tilts due to motor speed
difference.
Upon finishing installment, please test the airplane in VTOL mode. The option "Hover Yield" (CTL menu with
a default value of 6 degrees) will help you to keep the plane hovering straight (without leaning forward or
backwards). In VTOL mode, if the airplane leans forward, please reduce the value and if the airplane leans
backwards, please increase the value.
To calibrate the center point you can place the airplane upward and directly calibrate sensor's midpoint
instead of horizontally calibrating the airplane. If the airplane is in normal status, you just place the nose upward
to make sure that the horizon line in OSD is in middle position in VTOL mode. And then you place the nose
forward to make sure that the horizon line is in middle position.

- Page 2 Switching between modes: After finishing assembly of the airplane, you can test the stability of the airplane in VTOL mode. Then fly the airplane in balance mode. While switching mode the throttle shall be properly controlled: throttling up to switch from VTOL mode into balance mode and throttling down to switch from balance mode into VTOL mode.

Beware of the orientation of the part (colored in red). It should be aligned with the two side panels. Meanwhile be careful with of the position of the two side panels, don't glue them reversed.

- Page 7 Arkbird VTOL Assembly Manual v1.0 (Beta) Assembling the wing: Use the carbon sheet and carbon tube of 2mm long. Locating the wooden rudder bar on the airfoil, using carbon tube of 2mm long to cross through the rudder hole and rudder bar. Making sure the front of rudder bar and the rudder hole is on the same side.
- Page 8 Finally, assemble cover plate as shown above. Beware of its back and front. The wire of camera servo should be connected to channel 7 (output). In balance mode and VTOL mode, the airplane can automatically control the camera and keep it horizontal. And the camera can move up and down by setting the value of channel 7 to a dial in your transmitter.
