Drone battery
Drone battery charging

The drone uses a 3S smart lithium battery with a capacity of 4200mAh and a nominal voltage of 11.1V. Standard equipped with a smart charger. The charging time is about 1.5 hours.

① Insert the battery charging plug into the connector.

② Connect the power adapter to the AC power supply.

③ The current voltage will be displayed in the charger.

④ Please make sure to charge the battery at an ambient temperature between 0-40°C.

⑤ The charger displays FUL and 13.0V alternately, which means the battery is fully charged.

  1. If the battery is used in a low temperature environment (-10°C to 5°C), please fully charge it and warm the battery to above 10°C before use.
  2. Using the battery in an environment below -10°C will cause unpredictable consequences.
  3. In a low temperature environment, the actual discharge capacity of the battery will be significantly smaller than the theoretical discharge capacity. Please stop flying immediately when the APP recommended “low battery alarm”.
  4. In a low temperature environment, due to the limitation of battery output power, the wind resistance of the drone will be reduced. Please operate with care.
  5. The temperature of the intelligent battery is relatively high after flying, please recharge after it drops to room temperature.
  6. The allowable charging temperature range of the intelligent battery is 5°C to 40°C, and the best charging temperature range is 25±3°C. Charging within this temperature range can extend the battery life.

When installing the propeller, please carefully check the white dots on the drone motors and the orange dots on the propeller blades, and tighten them.

Remote controller charging

The remote control is charged with a Type-C USB data cable, please see the No. 17 mark

The charging time of the remote control is about 2–4 hours. The power-on icon of the remote control flashes when charging, and the icon goes out when it is fully charged. The use time is around 5–8 hours after being fully charged.

Remote control antenna angle
  1. Adjust the antenna angle of the remote control, and try to face the flying direction of the drone as much as possible;
  2. Do not block or cross the antennas.
Please use Skydroid Fly APP, you can download by scanning the QR code from the card in the package or from our oicial website:
App main interface
Basix flying
  1. Fully charge the battery before flying.
  2. Put the drone on a flat and open ground with the user facing the tail of the drone (the battery tail plug is the tail of the drone).
  3. Install the propeller correctly.
  1. Turn on the remote control (long press the power button), and insert the battery plug into the power supply port of the drone.
  2. Wait for the drone motor to make a long beep before the self-check succeeds.
  3. Open the Skydroid Ground Station APP and click on the connection icon to connect to the video/image transmission. The GPS mode is recommended for take-off. It will search for satellites automatically, when the numbers of satellites more than 12 pieces, it can unlock and take-off.
  4. Move the joystick upside-down “V” mode to unlock the drone, and slowly push the throttle joystick upward to let the drone take off smoothly.
  5. Pull down the throttle stick to land the drone.
  6. After landing, pull the throttle stick to the lowest position and hold it for more than 3 seconds until the motor stops.
  7. Plug out the drone battery from the drone tail and the power of the remote controller in turn after stopping.
Drone functions
Flying mode

Flying mode (the flight controller will judge the GPS signal, please switch the correspond- ing mode)

Altitude fixed mode

When the GPS signal is poor or the compass is interfered, the drone will enter “Altitude Fixed Mode”, which only supports manual flying. In the fixed altitude mode, if the fixed point of the drone is abnormal, please land as soon as possible.

GPS mode

Use GPS to achieve precise hovering and stable flying mode of the drone.

Return Mode

When the drone is switched to the return position or loses control, the drone will climb to the return altitude and return automatically.

* The flying mode is set by the three-position switch of the serial number 2 of the remote control.

Flying speed

Low speed

Maximum speed 2m/s, ascending speed: 1.2m/s, descending speed 0.4m/s

Medium speed

Maximum speed 12m/s, ascending speed: 4.2m/s, descending speed 2.0m/s

High speed

The maximum speed is 17m/s, the ascending speed: 5.1m/s, the descending speed is 4.9m/s

* The flying speed can be changed in “Gear Settings” in the APP.

Home return automatically

The return methods of the drone are RTL return, smart low battery return, and lost connection return. When taking off, GPS>12 pieces, the drone will successfully record the home point. If it is forced to take off without GPS signal, the latest GPS>12 piece position will be recorded as the home point.

Return process

1.Record the home point

2.Trigger the return home condition

3.Adjust the direction of the nose

4.Return home based with the seing in the App

(1) Ignore the current altitude of the drone, if the drone is within 5

meters of the horizontal distance, it will land directly.

(2) If the drone is 5 meters away and within 20 meters, it will return at

the current altitude, and the minimum return altitude is 5 meters.

(3) At a distance of 20 meters, the drone will return directly above the

return altitude. If the return altitude is less than the set return altitude,

the drone will firstly ascending the return altitude and then, return


One key return home

APP one key return home / remote control button one key return home

Return home with low battery

  1. The drone will automatically return to home on low battery or according to its distance to the Home point.
  2. If there is no GPS signal or weak signal when returning home with low battery, it will land automatically.
  3. When taking off, if it is forced to take off when the GPS signal is not good, the drone will automatically return to the place where it got a good GPS signal for the first time.
  1. If the power is less than 10% or the voltage is less than 11.1V, it will enter the landing mode.

Lost connection return

When the drone loses connection with the remote control for more thanb 2 seconds, it will return home automatically.

Performance requirements:

(1) After the drone loses control for 2 seconds, it will trigger automatic return home;

(2) In the process of losing connection and returning to home, if the drone is connected again, the drone will continue to perform the returning procedure;

(3) Land directly when there is no GPS signal or the signal is not strong.

Gimbal pitch adjustment

The H12 remote control uses the right-hand thumb wheel to control the tilt of the gimbal.
