Yuneec ST16S Troubleshooting

ST16S is not releasing sound or sound is distorted.

The speaker itself may be faulty and will need to be replaced. For instructions on replacing a faulty speaker, visit this guide.

The joystick response is very slow and sluggish or completely non-responsive.

The bases of the joysticks build up oxidation and will need to be cleaned every once in a while. You can do this by spraying the base with an Electrical Contact Cleaner and moving the joysticks around a little bit.

The joysticks themselves may be faulty and will need to be replaced. For instructions on replacing a faulty joystick, visit this guide.

The controller takes too long or loses charge.

Make sure that the USB cord is working. If not, look to get a new USB cord. If that doesn’t work try taking out the battery for about a minute and plug it back in. You may also try taking the battery out of the controller and charging it itself.

If you’ve tried the options above and the battery still isn’t functioning properly, it may need to be replaced. For instructions on replacing a faulty battery, visit this guide.

Carrying handle is cracked or broken.

The handle might have been dropped causing the handle to crack or break. For instructions on how to replace the handle, visit this guide.

The drone does not move with joystick input.

The ST16S uses two antennas, mounted on the top of the controller, to connect to the drone. Broken or missing antennas can be easily replaced using this guide.

If you believe the problem is with the drone itself and not the controller, search for a guide on the drone model you are using.
