    1. Wiring Use 3P wires “black (ground), red (power), white (data)” (Note the polar of camera wire, DO NOT POWER ON before carefully check. Especially 12V , incorrect wiring will damage the autopilot permanently!)...
  • Page 4: Power Supply

    Otherwise, use one battery (2S-6S) to supply flight power, another 3S battery to supply OSD 12V&Video (Separated supply). Power Supply Diagram Arkbird sensor’s 3P wire can wire in the flight power. 1. If 3S battery, plug in the jumper (Default), it will supply power to 12V Video system (Arkbird OSD 12V , Video TX &...
  • Page 5 2. If separated supply, remove the jumper, connect another 3S battery (800mah-1000mah) to the Video Power Port (12Vin) on the third row. If separated supply, the sequence to power on is OSD 12V first, and then ESC flight power. Otherwise, the OSD cannot initialize and display.

    3. Installation: The pins of Servo & Radio RX shall stay forward (toward flying direction), the side with wing. (Default is level installation) soldering dot shall be upward V ertical toward right Put on heat-shrink tubing, fix by sponge and cable tie. Please keep away from motor to avoid vibration which will reduce the accuracy of sensor.

    5. GPS & Save Home Position After power on, Arkbird will start to search GPS satellite and save the first valid position as Home. During searching, the elevator will be up and any manipulation of radio stick is invalid. If need to skip the searching, please push CH6 more than 75% and push CH1 to left or right side for 1 second.

  • Page 17: Balance Mode And Rth Adjustment (Very Important)

    11. Balance Mode and RTH Adjustment (Very Important) Arkbird’s default parameters will be ok for most plane types. But if the most ideal situation expected, please refer to the following methods: First time installation, do a neutral point alignment. Plane shall be put paralleled to the ground before neutral point check, moving aileron stick left and right to get start.
  • Page 18: Frequently Asked Questions

    Adjusting Return to Home Mode: “Home Direction,” “Roll Angle,” “Pitch 1. Switch to RTH Mode, Important parameters Angle,” and “RT H Throttle” shown on OSD shall be checked all the time. Flying to certain height, switch to RTH Mode and check if these data are appropriate. Adjust RTH parameters referring to these values.
  • Page 19 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.
