This is my first project, please help.
I have S500 V2 kip with px4 and Flysky remote with FS-IA6 receiver.
I don’t now how to connect px4 with FS-IA6 receiver.
In the doc:
is mentioned to use SBUS port or PPM RC port.
But for me is not clear how this is possible, receiver has 6 channel and I have 2 cables with 3 contacts.
What is the solution and how to wire the remote?
It looks like you need to configure the fs-IA6 to PPM mode and then connect one of the channels (not sure which one?) to the PPM input of the Pixhawk.

That I already done, not working.
I don’t know how to connect wires from px4 PPM connector to FS-IA6 receiver:
https://www.amazon.com/Flysky-Receiver-Compatible-Transmitter-RC210/dp/B01GDZ2D8W
This receiver has 6 channels with 3 pins each.
From doc, is not clean how to do it:
https://docs.px4.io/master/en/assembly/quick_start_pixhawk4.html
Still waiting for a solution.
When PPM is used, all channels are transmitted over one “cable” (including the signal (white or yellow), 5v (red), and ground pin (black)).
I assume when PPM is selected it will come out of channel 1 but I don’t know that. I have not used that hardware myself. If I was you I would try 1 and if it doesn’t work try the others too.
I tried almost all combinations for PPM and SBUS cables, with all channels, nothing works.
When connecting to QGroundControl, it say’s that for remote I have 0 channels, but is need 5 channels communication.
I suggest you share a picture of your setup. Maybe we can spot a mistake.
I have this 2 cables from SBUS and from PPM.
How I should connect them to channels available on receiver?
I enable PPM output on Flyscky remote. PPM out is set on channel 1, by default.

On the Pixhawk side I think you want to use PPM RC.
Then on the receiver side eyou might want to use the one next to channel 1 labelled S±, at least that would be my guess.
Only FS-IA6B supports PPM-S.
This is a kind of hidden information in datasheet !!
@Bravepaulo can you confirm FS-IA6B works in ppm with pixhawk 4?
Hi @Matteo_Scanavino
In my setup, I use a PIXHAWK 2.4.8 with FS-IA6B PPM and it is working fine, as consequence I cannot guarantee 100% that it will work with PIXHAWK 4. On the other hand, considering that such stuff does not change much among PIXHAWK models (at the end of the day is a PPM port) my guess is that there is a great possibility that it works as well.
If you need any support feel free to contact me.

can you please send the wiring connections you used connecting px4 and fsia6b?
can you pls show the wiring connectiond with FS iA6B
Hi @Huy_Quang and @sabih_sultan.
Please find below some pictures to help you out.
Let me know if I can help with something else.

Hi @Bravepaulo I have Flysky transmitter FS-i6 model and receiver FS-iA6 which supports PPM . But I am confused here is PPM and PPMSUM is same thing. I am connecting the receiver but no luck. Should I buy FS-iA6B receiver. Will it work with FSi6 trasmitter.
Hi @vikas_kumar .
I am not sure about PPM and PPMSUM question.
On the other hand, regarding the receiver, only FS-iA6B supports PPM. If you want to use PPM serial port, you have to use a FS-iA6B.
I did not mention this in my previous post, but I also use FS-i6 radio transmitter.
Let me know if I can help you with anything else.

Thank you @Bravepaulo for your reply. Looks like I have to buy FSiA6B receiver and again try connecting flysky RC with pixhawk.
Also , do you need to enable ppm on pixhawk or it is enabled by default. I looked for difference between Receiver FS-iA6 and FS-IA6B but there is no difference except for longer range.
I have FS-IA6 receiver and FS-i6 transmitter and pixhawk 2.4.8 . I am using MissionPlanner for the control. When I connect with the pixhawk Transmitter and receiver bind successfully but I am unsure whether pixhawk recives the RC signal or not.
Is there a way to check it. ??
If you are using any other UAV software then kindly let me know.
Hi @vikas_kumar.
I work with PX4 and QGroundControl, and there is no need to enable PPM for this setup.
I am quite sure that the range is not the only difference between FS-iA6 and FS-IA6B. I believe the FS-iA6 has no PPM output.
On QGroundControl you can check the RC signals when you connecting the PIXHAWK (via USB or radio) to the computer running QGroundControl.
I am quite sure Mission Planner has also this feature.
Follow below a figure to illustrate it on QGroundControl.
If connected, the small white dots will move as you move the radio sticks.
Let me know if I can help you with anything else.

Yes It works fine now. I brought receiver FS-iA6B and now it is working fine on both the GCS softwares i.e. QGroundControl as well as MissionPlanner.
You are right; FS-iA6 and FS-iA6B are different not only in terms of range. They might be varying in the signal output type also.
Everything is working fine. Also , I would like to point out about Enabling PPM RX in the transmitter, as mentioned in previous replies.
Thanks for your helpful reply.
