Flight Operations

Mobile phone connect with Drone
Download and install APP: UDIGPS-PRO This software is suitable for mobile phones in the IOS 9.0 or later and Android 4.4 or later system. For detailed operation, please check tthe he system “HELP” of the APP.

Transmitter connect with Drone
Frequency Pa,iring

1. Turn on the power.

2. Pull the left stick to the lowest position and let go, the light goes off slowly. it indicates the transmitter enters the frequency state.
   The drone is placed on the horizontal ground, and long press the power button for 2 seconds to start the machine. After the navigation light is on for 2 seconds, the front navigation light flashes and the rear navigation light goes out. At the same time, the remote control emits a prompt sound of “di”, indicating successful frequency alignment and entering the horizontal calibratthe ion of compass.

Compass calibration

Rotate the drone horizontally until the transmitter sound “di…” Level correction to complete. When the front navigation light turns to long light and the rear navigation light flashes, enter vertical correction. rotate the vehicle vertically until the transmitter sound “di…”, vertical correction over. The lights are spinning and flashing.
Tips: It’s a must to have the right compass adjustment first each time you start the drone, or it can’t work normally.
Calibration (This action is used when flying abnormally)
After the calibration of the compass, the right stick of the transmitter is pushed to the lower right corner by 45°, and the transmitterthe  emits sound “di”, and the drone light flashes and releases, indicating that the gyroscope has been calibrated. (drone should be placed on horizontal ground)
Tips: When the drone doesn’t appear to use the trim correction flight statis us, or being hit hard (or falling abnormally). Thus cause the difficulties in controlling. Now frequency making and adjustment are needed the again, drone should be placed on horizontal ground.
GPS Signal Search
After the frequency matching is successful, the drone automatically searches for GPS signals. When the blue indicator light of the remote control changes from flashing to long bright, it makes a sound of “di” at the same time, indicating that the GPS connection is successful. (when the GPS signal is weak or flying indoors, the flight height defaults to about 4 meters)
Unlocking the drone
Push the left and right stick inward to the 45° angle simultaneously.

• On standby drone, motor rotation, drone Unlocked.
• When the drone is not take off, the motor stops rotating and the drone is locked.

The function is standard by the mobile phone APP signal, so it’s a must to make the drone and APP connected normally, and turn on the mobile location service at the same time, otherwise, this function is invalid Note: follow the maximum range distance, within 1000m of the take- off point.
Encircling flight
In flight, press the “ ” button, and the transmitter will make the sound of “di”. Then it goes to the function of encircling flight. The drone will fly to a default radius then it waits for the direction controlled by the user. Adjust the speed and direction of the drone by manipulating the right stick. It is the minimum radius of the default radius acquiescently, so the drone flies only in the sub-range.
Speed mode switch
Medium speed default
Press the “H/L” button, and the transmitter will sound “di.di.dia to enter high-speed mode ‘H
Press it again, and the transmitter will sound “di” to enter low-speed mode “L”.
Press it again, and the transmitter will sound “di. di” to enter medium speed mode “M”.
