Q & A

1.Can the remote control install other apps?
The permissions of the remote control are all open, and there is no special software or restricted
software installation and uninstallation. Supports specialized customized QGC App to be installed, K3A App can’t support now.

Check whether the corresponding remote controller has been selected in the ground station App and whether the baud rate is consistent with the flight control (H12 helper, advanced setting,password is 999, receiver setting baud rate). Check whether RX TX is connected reversely (the right way is connect controller’s RX to receiver’s TX, and controller’s TX to receiver’s RX).
3.The remote control keeps ringing/beeping.
When the remote control is not successfully connected with the receiver, the remote control will always send out a prompt alarm.
4.The QGC sound is too low to hear?
Please set it in Vol+/Vol-section.
5.What else can the TYPE-C port do besides charging?
In addition to charging, the TYPE-C port can also be connected to a computer for file viewing.
6.How many ways to connect the remote control to the network?
