Neil, glad you were able to update the radio but I suggest you should always make a backup file before you do any updates. This way you can always go back to the previous file if you need to or in your case you can download all the model info from the previous file to the new one and you do not have to manually input all the model info again.
Anyone using the Flysky FS-ST8 there is an firmware update that increases the radio from 8 to 12 channels. In addition there is also a 12 channel receiver available, FS-SR12.

Was waiting for a rainy day to do the upgrade to one of my Flysky i6 Tx, today was that day.

Found I'd run out of channels for my Perkasa as it runs a 180 degree servos for each of the two guns and a channel for the sound unit in addition to the usual throttle control and steering. I want to add 2 switched channels for the water pump for cooling the motor and ESC and a switched channel for the RADAR motor.

Read on here it was quite straight forward to upgrade the firmware so ordered the appropriate cable.

The main issue I had was that I've been a Mac user for the last 12+ years. Once I started using cloud systems and external hosting I moved over to MacBooks, never looked back.

Current one doesn't have a Windows partition as I gave up Boot Camp and Parallels etc years ago. Did mean I had to use a Windows device to do the firmware update, found a Microsoft Surface Pro in my study that hadn't been used for 4+ years, so that had to run numerous updates before coaxing it back into life.

Luckily the Surface has a single USB port had to hunt for a generic Windows driver but once connected to the Tx the rest of the upgrade was done in a couple of minutes.

Now very happy with the results, luckily I made a note of what models were on the Tx as I'll have to rebind a load of Rx at some point, but knew that I'd lose all the existing models when doing the update.
