Fly-Sky Configuration
and Helicopter Setup Manual

Getting Started

Special Note: A new software package for the FlySky CT6-A radio has been created by Stephano Grassi named “Digital Radio” which is very easy to use and has additional functionality. All of the setting information contained in this manual can also be used with that software package. You can download the Digital Radio package from

Start the application, and plug your (already installed and configured USB interface) cable into the back of the transmitter. Turn on the transmitter.

There are four sections to the main screen (Fig 1).

Each of these sections and individual options will be described in detail.

Connect the Radio to the Software

Fig 2

Verify that your radio is communicating with the software.

Not Communicating

Is Communicating

Fig 3

If your radio is not communicating to the software, you need to click the Settings button in the System Option section. This will display a serial port selection dialog where you can pick the serial port your computer assigned to the USB cable. Typically this will not be the first COM port, as any other installed computer serial ports will consume COM1 and COM2. The Fly-Sky cable that comes with your radio is a USB to Serial converter. There are two models of this cable, and they are not marked. Some use the Prolific USB Chip, and the later versions use a Silicon Labs Chip.

See for links to the drivers.

Fig 4

If you do not know the correct serial port, try all of them until your graphic signal chart displays with bars (Fig. 4). Wiggle the control sticks on the radio to confirm the radio is communicating (Fig.3). The bars will change if communications has been established.

*Note: It is a required to click the Get User button after establishing communications with the radio. This forces the T6Config.exe software to clear its memory and read the real settings from the radio back into the software. Failure to do this may cause issues or loss of configuration information when you make changes or save the information to a file. The T6Config setup memory contains 67 bytes of binary information. The Get User button replaces the software's 67 bytes of data with what it reads from the radio. If you do not use the Get User button immediately after you begin communicating with the radio, and you make some minor change, that change along with whatever the software has in its own 67 byte package is immediately sent to the radio replacing whatever it originally had stored.

At this point, you have learned how to connect your radio to the software, and force the software to read the settings in your radio. Before moving on to the System Settings section, lets review the remaining three buttons in this section.

At this point, you have learned how to save and load configuration settings from files on your hard-drive.
