    Don't switch to PPM, see my reply in the ibus thread...

    It will work, but what he has will work at no cost and ibus is better than PPM anyways.

    Ok live and learn I guess Green.
    That’s what I love about this place. Fantastic advice.

    I have flysky i6 tx and I6b rx. Holybro kakuba f4 v2 fc. I see the terminal for sbus but I read ibus is different so I think that pad won't work. I see another pad that uses the appropriate signal. I will enable that uart in ports and see if it works. Otherwise maybe my tx needs updating to do ibus. I have an omnibus f4 fc coming from Amazon tomorrow which uses ppm. I don't have any problem with ppm

    No update needed, use any available UART rx pad except for UART3 and UART1 (labeled SP). I think that only leaves UART4 and UART6, use one of those two.

    Compared to ppm, ibus has better noise rejection, higher resolution and needs no endpoint calibration.

    I agree. Use ibus when possible. Better response between transmitter & receiver. Also, it's serial communication, so you only need one wire from receiver to FC.

    Hello update I never got ibus to work. I I'm using the sp f3 from the 100$ build for now qav 210. And omnibus f4 v2 on the qav130. Tweaked my pids a bit. Both flying great. A bit faster but transitioning after flip and roll nicely. Nice punch outs with flip and rolls. Thanks on all my posts.

    F4's are great! But you are not using iBus, still PPM? The Omnibus F4 is a good board. Let me know if you wanna try iBus on it again and I can help you with that.

    I think my flysky trans won't do ibus. I tried to set it but it won't work. Ppm is fine

    If it is an fs-i6, it does ibus. Flysky invented ibus, so I would hope it works! You do need to select AFHDS transmission protocol in the radio menu when switching over, did you find that setting in the radio menu? Anyways, no big deal if you just want to stick with what is working.

    It should. If you look in your RX setup mode and scroll all the way to the bottom, it should say iBus and set to channel 1. This should work fine. You need the FlySky FS-IA6B to use iBus though. And sometimes you have to flash the FC firmware to get the receiver communtication to respond. This happened to me twice, but they both started working after latest firmware flash to the FC.
