7 .GPS and Return to Home Instruction
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.
Once skipped the searching, it CANNOT switch to RTH mode, and the LED will flash slowly.
While switching to RTH Mode (CH5 to 100% and CH6 to 100%), it will adjust the flying height to
safe height to go home.
Considering throttle safe, when height and distance is within 30m, there will be no any throttle
output, to avoid any hacking while adjusting.
During RTH mode throttle will increase if altitude is low, or speed is slow, decrease if altitude is
high, or speed is faster than set safe speed.
Once lost GPS satellite, switching to RTH, the plane will go home automatically based on the
home angle of last position before out of signal. Within radio range, please switch to Balance
Mode and land.
