Read this FAQ post to easily solve your Hubsan H109S X4 PRO quadcopter's flight, transmitter, propeller, GPS signal problems.

Hubsan H109S X4 PRO

The transmitter itself hasn't GPS signal. If you want to fly the drone in GPS mode, go outside where has GPS signal and without signal interference. Besides, wait for a while to obtain GPS signal as the drone needs time to search GPS signal after open the GPS.

There are many reasons that cause the Hubsan H109S X4 PRO drops off while flying and you can solve the problem according to them.

You operate the Hubsan drone wrong. It's easy to out of control and deviates the direction if you haven't decoded the drone properly before the flight. Also, pull down the throttle by mistake is another reason which results in the trouble. So, you should decode the drone correctly before flying and operate it carefully.

The drone is lack of battery power. Just fully charge your Hubsan H109S X4 PRO before flying. If you are not sure that the battery is full or not, use a multimeter to test the 11.1V battery - 12.6V is normal which means the battery is fully charged, the tested voltage exceeds 12.6V means the battery is over-charged and it's damaged.

You haven't calibrated the Hubsan H109S X4 PRO in a right way. Make sure that the drone has enough power and decode the drone properly, then follow the steps to calibrate the device:

A. Hold the throttle stick fully down, flip the GPS switch quickly until the transmitter displays "Calib compass 1".

B. Rotate the X4 PRO in clockwise until the LCD screen displays "Calib compass 2"

C. Put the X4 PRO nose down and rotate it in counter clockwise until the "Calib compass 2" disappear.

There is signal interference around your drone. Choose a wild place outside, where haven't obstacles and high voltage wires, to fly the drone. Here is a similar fly guide for Mi drone which you can read for reference.

The transmitter has run out of its battery power, thus you cannot control the Hubsan drone. Just change new 1.5V AA batteries for the remote control.

The Hubsan H109S X4 PRO is out of control distance. The control distance of your Hubsan quadcopter is about 1500m so that you should fly the drone within the distance.

● Check whether the propeller installs too tight on the electric motor. If yes, please adjust the tightness (loosen it) and then check whether it can spin normally.

● Uninstall the propeller and check whether its electric motor works, if yes, the propeller has something wrong. In this case, simply change another blade.

● If the motor doesn't work, please take off the drone case to check whether the electronic motor cable connects to the main circuit board well or the shaft gear installs well. If not, just fix it in an RC store. If yes, the motor is damaged, please change a new one.

● Place the quadcopter on a horizontal surface, pull the throttle lever to the right down corner and the direction lever to the left down corner at the same time. This time the indicator of the aircraft will be flashing quickly, and then loosen all the actions on the transmitter and wait till the indicator shows eternal bright and the calibration is successfully finished.

● However, if you tried all above steps, but the propeller still can't spin, its electric motor must be damaged. You can take it to an RC shop to check and repair or change the component.

The control distance written in the product description is about 1500m. But the actual maximum control distance is less than 1500m because the flight is affected by weather, wind, signal interference, etc.

In addition, the drone or its transmitter less of power will lead to the Hubsan drone only fly shortly. In this case, charge your drone fully or change new batteries for the transmitter before fly.

Try to change a frequency for longer control distance and better video transmitter.

A. Pull the throttle stick down, then hold down the ENTER key for 1 second to enter the setting interface.

B. Move the arrow to the 5.8G frequency with UP / DOWN key.

C. Press the ENTER key again and select the frequency you need with UP / DOWN key.

D. Hold the EXIT key for 2 seconds to confirm and exit.

Compass calibration is required before the first time flight otherwise the system may not work properly. Here is how to calibrate your Hubsan H109S X4 PRO:

A. Hold the throttle stick fully down, flip the GPS switch quickly until the transmitter displays "Calib compass 1".

B. Rotate the X4 PRO in clockwise until the LCD screen displays "Calib compass 2".

C. Put the X4 PRO nose down and rotate it in counter clockwise until the "Calib compass 2" disappear.

The drone is lack of battery power. Just fully charge your Hubsan H109S X4 PRO before flying.

The transmitter has run out of its battery power, thus you cannot control the Hubsan drone. Just change new 1.5V AA batteries for the remote control.

The motor or ESC on your quadcopter is damaged. Go to a fixing store to change a new motor or ESC, or ask the seller for further help.
