Hi guys, I have an iRangeX version of this RX connected to the micro 'realacc f3 acro board(v1)' More huge thanks for to Sandra and banggood for these! I am having difficulties with beta flight... I have flashed the board with Omnibus FW and it's recognising the board but whenever I change UART (1,2 or 3) to serial RX and select receiver as 'serial based receiver...' -> iBus. When I click save and reboot it doesn't save the changes from either ports or config tabs? Can't understand what I'm doing wrong?!

Are you pressing the save button in each tab of the configurator? If you don't save your first change in the Ports tab, the changes in the Configuration tab make no sense and won't be saved.

Thanks for the reply. Yes, saving and rebooting between tabs. Rx binds successfully but no response from the quad or from beta flight, even the motor test in beta flight fails to make anything happen...
Can you show us exactly how you have connected the receiver to the flight controller? Also, which radio are you using to talk to the receiver?
What happens in the Motors tab is nothing to do with the receiver and there won't be power for the motors to spin unless the board is connected to a battery. USB alone won't power the motors.
To check if the receiver is working, you should be looking for movement in the channel values in the Receiver tab.

Not sure if this helps but, when I click save and reboot, configuator fails to reconnect and I have to manually click connect again. Checked the soldering for the RX and it looks fine.
Using the fs i6x clone TX from iRangeX, and the fs-a8s clone RX that came with it also from iRangeX.

Nah, some of my flight controllers don't auto reconnect after a save either.
So, on the radio, how have you set the "Output" option for the receiver? I think that if you set it to PPM, then it won't output iBus. Also, are you connecting the i/s-bus cable to the receiver port on the flight controller?
The receiver port on the flight controller is UART3, so that's the port that you should set as SerialRX. You also need to double check which type of signal the receiver is going to output as it can be switched between S-Bus and iBus.
To help more, I really need to see pictures of how you've connected things and maybe even a dump from Betaflight.
OK I will get some photos uploaded in a bit, from the wiring diagram photo here - http://m.banggood.com/Realacc-F3-V1_0-Be...21378.html I have connected ground, positive and signal (sBUS/iBUS) to the top (as the photo shows) black -> ground, red -> 5v (despite info saying that the RX will work with 3.3v) and white (sBUS/iBUS) -> RC_in.
After deselecting MSP and selecting serial from ports configurator is now saving changes to the RX. still no stick inputs showing though!
Your photo isn't very clear, but it looks to me as if RC_IN is shorted to 5V.
Running your VTX off the 3.3V pin will not work. I don't know what VTX you have, but it will draw far more current than the onboard 3.3V regulator is able to supply.
If that extra load is causing the 3.3V supply to collapse, that may well explain some of your problems.
I dont know what vtx it is, I did check before and saw people saying that they had fried it with 5v and suggested connecting to 3.3v. I know the camera on this phone is rubbish but it's definitely not shorting. Maybe I'll disconnect the fpv rig for now considering I have nothing to view it on!
Where did you get the VTX from? I'm surprised it doesn't take 5V.
But anyway, if you've now managed to set UART3 as SerialRX, have you now set the receiver mode to RX_SERIAL and the Serial Receiver Provider to IBUS? Have you also checked whether your receiver is set to output SBUS or IBUS?
Set TX for ppm output and ibus serial, I have cut the ppm wire off the RX, not sure, maybe its supposed to be connected as well? Disconnected the 3.3v feed for the vtx. Still no response.
Its possible that I might have made a mistake with the TX setup, I haven't flown with a proper TX before!? iRangeX iR-i6X TX (fs-i6x) clone. Stock firmware Model type : fixed pitch heli or glider/plane - no response. The heli and plane options seem to change the aux switches, so tried to set arm and failsafe to all the different switch options. Might still be doing something wrong tho!

It came from Oscar's cjmcu micro, via his house moving giveaway, (it's over 2 years old, so in this hobby, its probably almost an antique by now!) I found the part number and looked it up, which is where I found the info on voltage.

I have heard that the a8s RX is not saving sbus selection and that it reverts to ibus, thought I would just leave it standard, though I have tried to change it, but it didn't seem to make a difference. You mean set receiver mode in configurator? Yeah, done, saved and no response!
It sounds like you probably have it set up correctly now. If you can post a dump from Betaflight then we can double check. If that looks good then the only thing is to try a different receiver or even try your receiver on another flight controller.
