ARKBIRD-Tiny3(T3)Product Features:
ARKBIRD System is a high-accuracy autopilot designed for fixed-wing, which has capability of
auto-balancing to ease the manipulation while flying.
(Extreme small, only 1.8 * 1.5cm, weight only 1.7 grams),
Super stable , plug and play. Capable of high-precision control of level flight, 3D flight, etc.,
combined with GPS, it can achieve RTH(return to home), fence mode (Out of area or under safe
altitude, it returns automatically, best helper for beginner), etc;
When only be connected to the steering wheel , used as a taxiing rectifying gyro, It corrects
the airplane off tracking tendency, and accurately responds to the direction of the rocker steering
action. for Electric Ducted Fan (EDF) and Jet power scale model airplane and so on.
automatically, best helper for beginner
7.Semi-Balance Mode When the CH1 and CH2 of rocker is less than 50%, the plane is in
Balance Mode. When the rocker is more than 50%, the plane is in Gyro Mode.
Reminding:
For the first installation, please power up after a
(incontrollable) every time you power up. You can cancel it manually and adjust rudder angle directions in

and
auxiliary control
fail-safe protection
for the receiver in case your autopilot loses control when returning home.
For the first flight, we suggest taking off with "Manual Mode". Check if the aircraft flies normally after
switching to "Balance Mode" in a level flight. Then switch to "RTH Mode" and check the autopilot by using
parameter (see the last chapter in the instructions:
important parameters during the flight (Vibration value, Satellite number, Speed and Altitude).
When the maiden flight test is done, Balance Mode can be used freely for taking off the autopilot, or you
can use extended functions such as waypoints, cruise flight or fence mode.

1.Controls the steering angle of the steering wheel.
2.Can be installed flat wise or sidewise, suitable for small aircraft.
3.One button auto-leveling, stick back to center, plane can fly levelly.
4. One button RTH (return-to-home), lost radio signal return-home.
5. Hover mode Regard the hover position as balance position, nose up
and keep steady;
6. Fence mode Out of rectangle area or safe height, it returns
in Balance Mode. A

Switching to Manual Mode, Arkbird will not participate control, set manual control’s reverse through radio, adjust plane’s CG and travel angle.
  • Page 8 Arkbird 1. Aileron: When rolling the plane to right, aileron shall produce a left compensation automatically, make plane go back horizontal. On the contrary, when rolling to left, aileron will produce a right compensation. Please see as below: If the compensation direction is not correct, please adjust the Roll inverse.
  • Page 9 Arkbird Please adjust the sensitivity and adjust the mechanical rudder hole and by turning the 5/6 channel. Adjust the output of the 25 degree control surface corresponding to the joystick as shown in the following figure: Please increase control value when the stability not good enough under Balance Mode (drift even stick back to center), Decrease control value when the plane swings,.
  • Page 10 Arkbird GPS and Return to Home Instruction While switching to RTH Mode (CH5 to 100% and CH6 to 100%), it will adjust the flying height to safe height to go home. If the throttle safe is enabled and when height and distance is within 30m, there will be no throttle output, to avoid any hacking while adjusting.
  • Page 11 CG and travel angle to make plane balanced. Arkbird can produce compensation when CG & travel angle is not appropriate, but it is not mechanical stable, there would be hidden trouble under RTH mode. So firstly make sure plane can fly stably in horizontal under Manual Mode.
  • Page 12 Arkbird Attention: Please read through carefully: 1. The design purpose of autopilot is to keep balance of flight, it is not able to manipulate plane or prevent stall. You must have sufficient experiences of fixed wing to control the flight.
