Hi,I have a question to the FrSKY X8R receiver.Is it possible to use the conventional 8 PWM channels on the X8R and use at the same time the "FrSKY SBUS to PWM Decoder" to get 4 extra PWM channels, in all 12 PWM channels ?Also would I need the "FrSKY Servo Channel Changer" to set up the 4 extra channels ?I'm planning to use the FrSKY Taranis X9D 16ch radio.I know it's possible to combine two X8R receiver to get 16ch, but in my case there isn't enough space to accommodate two receivers.Does anyone tried this before ?

Excellent it works!, I have 8 channels via SBus to my pixhawk and 8 more channels via analogue output for controlling my 2 gimbals(1x 2 axis FPV and 1x standard 3 axis) with spare channels todo other things!
Hello, I am not sure if I am following this correctly as some of the posts are confusing.. please validate....
If I have one Receiver (x8r) with SBUS-to-CPPM Converter with APM Inputs Jumpered between pins 2&3 and Output of the SBUS-to-CPPM Converter to the Pin 1 on the APM Inputs section with (-/+/S). Then effectively I have CPPM from X8R to one input on APM.
Getting the other 8 Channels is done by adding an additional X8R to the mix to pick up the other 8 channels to your device Quad/Hexa/etc (not APM).
Just to clarify, not that I am going to get 16 Channel input to APM on the 1 port being used on the APM.
Or,
Are you saying that you enabled the Analog ports on the single X8R Receiver as well so that you don't need a secondary X8R to get the other 8 Channels?
I think that is the possibilities.. could someone clarify one of them please.
You cannot send more than 8 channels out on a PPM port, this is due to the timing requirements. If you need to send more than 8 out one port you should look into using sbus.
Many thanks for sharing Brano, this make total sense now and I am very excited to have such a device to use. I was successful in setting up my Mini APM from HK and the FrSky CPPM Converter. One question, do you se 27ms when doing 8ch or the 22ms? On the old DR8P I flashed it to use 27ms.

Mode 4 on page 2 of the manual works!
Many Thanks!

Yes you can get 4 more channels out with the SBUS to PWM Decoder
Yes you need the servo channel changer to program which of the 16 channels the decoder puts out on its 4 outputs.
You should only ever need one servo channel changer as you unhook it after you program.
