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.

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.

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.

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.

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.

The new firmware for flysky fs-i6 radios has changed the menus a little bit. It now requires an extra setup step but the bonus is that the new firmware is better and also now supports up to 10 channels!

While you are on this menu you also might as well enable all 10 channels while you are here should you need them for whatever reason (with supported receivers). Once done it should look like the screen below:

Flysky FS-GT5 is a 6 channel rc car transmitter (and FS-BS6 receiver) uses 2.4gHz reliable AFDHS2a protocol. Beyond throttle and steering there are 4 extra channels allow user to run practically any auxiliary item with mixers also available for crawler steering and the like. Full gyro control via remote and a very easy to navigate GUI. NTN semi-permeable, segment screen, VA52.5 * 34mm LCD Screen white HD and noble display. Fit most RC car/ boat/ trucks

Specification:

Flysky GT5 F.SAFE Out of Control Protection - Through set out of control output value, you can set Multiple Channels Out of Control Protection, make the remote controller mode smooth and steady stop when accidentally disconnected

ABS function (automatic brake): This function only adjusts the throttle channel, including six kinds of parameter settings, automatic brake settings to adapt to different models of track, to achieve the best braking effect and cornering control effect.

Rc Crawler Truck CRAWL function (climbing car mode), SVC function (smart car control mode), gyro stability function.4 Climbing Mode - With 4 Climbing Mode, revolutionary control optimization for climbing cars, easier handling, more freedom to distribute functions

Flysky GT5 remote controller can store 20 models, each model can set the parameters separately, but also can write the model name easy to remember. Keep all cars specific trims and End Point Adjustment (EPA) setting data to avoid massive immigrating data from other radio transmitters.

I first saw this radio on YouTube. The guy was very excited about the settings, how good it was. When my steering on rtr got crappy I revisited the video, and decided to give this one a try. Happy I did

As the title says an affordable 6 Channel system with a lot of options for customization. The transmitter is well designed from the folding antenna. the option to use different batteries using the jst connector, the rubber grip and foam steering and the nice big well lit or should I say back lit screen. Unfortunately, the receiver that came with the radio was a dud. It wouldn't activate my new 9g servos but thankfully I got a second receiver with my initial order so I was able to play around with the available options on the transmitter. Plus it's very easy to program even w/o the manual. Plus it's nice to be able to store multiple cars/trucks in one transmitter.

Package was a little beat up but item was fine. This transmitter is awsome, at least for me because I'm cheap. The controls for a four wheel steer with lights or winches are outstanding for the price. The only complaint I come up with is the instruction manual is about worthless, so it took a little time and videos to figure out.

Best radio money can buy for the price ! Put receivers in both my boats and had incredible range ! I would definitely recommend these items ! Thank you hobbymatehobby for great service and great response !

FlySky's ST8 transmitter will be Your new best friend when it comes to controlling model aircraft. Due to the countless possibilities that are available for optical adjustment alone, the remote control can be optimally set up to suit Your own needs. A built-in STM32 chip from the all-new G series also provides the necessary technical performance. Simple and intuitive in design, this transmitter with 8 to 10 channels is suitable for beginners and more experienced flyers alike.

The standard version of the ST8 comes with a remote control and the associated SR-8 receiver. Any other receiver can of course also be used, as long as the ANT protocol is supported. Optionally, for example, a mobile phone holder or an RF head adapter can be installed. Even personalized LED lights under the transparent caps of the control sticks would be possible. So there really are no limits to Your own imagination.

Hi guys i was wondering if it is possible for nrf modules to catch and decode the signal of a flysky transmitter and use arduino+nrf as a receiver for the stock transmitter ?
Here I have a stock Flysky CT-6B transmitter and couple of nrf's .

Thank you Robin2 you have been always helpful for my queries regarding nrf's .I did make my own transmitter and receiver and it worked out very well but due to poor chinese joysticks used I was facing some issues in controls. Youtuber Iforce2D made using similar process and faced the same issue so he used joystick from an old flysky transmitter he had as shown in his videos .He clearly showed this particular thing. Since quality joysticks are not available here loosely hence i bought a barely used Flysky CT6B transmitter without receiver.
Hence I thought if without modifying the internals with arduino and nrf if I could catch those RF signals and decode then it might be better .
Thanks
Link to my makes: Nrf_Transmitter, airplane_using_same, Quadcopter_using_same

Thanks for the replies .I was going for replacing internals as suggested by Robin2 when I saw that it has a ps2 slot which is connected to pc for usage with simulator.
Researching on it I found that it gives a ppm output so I thought if I connect that pin to Arduino and transmit it using nrf hence I won't be needing to modify internals .
But my question is would I be facing a time lag ?

You need to detect the width of the pulses, in microseconds, and transmit the microseconds value for each channel (all the channels in a single nRF24 message). If pulses for all the channels are produced from the same output pin on the TX then your Arduino program will have figure out which pulse belongs to which channel. Speaking personally, I would just replace the internals.

I meant to decode the ppm signal and then transmit it using nrf24l01 in any form possible such as i used byte values in struct earlier and then decode and convert to whatever form you want in the receiver side.
Basically just instead of modifying internals use the ps2 pinout to access the internals.

I always appreciate your answers but still I wanted to try this since i knew this is possible hence i kept your answer as the last approach and further tried for catching and decoding those ppm signals and yes,
I did attain success!!!!
Here are some pics ,I'll upload the code and some explanatory pics tommorrrow as a tutorial like yours "simple nrf" so that it'll be beneficial for all.


P.S. The sole purpose of this was to use the transmitter maintaining its originality and hence i didn't want to solder wires and hack internals with arduino if possible(yes i made it possible )
I'll test it with receiver for time lag and stuff then post the conclusion and tutorial for attaining this.
Thanks @Robin2(always helps out) & @bluejets
