FlySky FS-i6 (or branded Turnigy TGY-i6) is a very decent 6 channel entry level RC radio system. But support for PPM (CPPM) standard is somehow not clear. I have no idea why manufacturer keeps PPM support data so well hidden. Anyway, here it is: how can I enable PPM on i6 radio system?

PPM signal is supported only on FS-iA6B (v2) receiver, FlySky FS-A8S Mini receiver and a couple of compatible ones: FlySky Pro Micro, FS82 Micro Receiver and iRangeX Tiny 2.4G 6CH Flysky Receiver

It is not possible to enable PPM signal on FS-iA6 receiver. So if you have simpler one, you would have to buy iA6B. Also, PPM signal is not enabled by default. To turn it on, you have to change radio settings:

Open Menu and select “System setup“

Enter “RX Setup”

Navigate to “PPM output”

And change it to “On”

This is all. From now on, FS-iA6B will output PPM 6 channel signal on port 1 labeled “PPM/CH1“.
