Hello,

I am totaly new to this hobby.. bough tinyhawk 2 and had lot of fun. Next I bought Taycan Diaton with mamba f405DJI MINI FC planned to use the goggles and radio from tiny hawks. So got together with mamba the reciever "EMAX Tiny 2.4GHz 8CH Mini SBUS Output RC Receiver Compatible FrSky D8".That should be only combination that would work with tinyhawks radio. 

So when everything arrived I solder the Emax reciever to the free wires which were for R-XSR. I was able to bind the radio with reciever. But in Betaflight I am unable to switch reciever to SPI RX and Frsky_D. Do you know why ? Attached picutre where it is soldered. I think it should go somewhere else or settings in betaflight should be different

Side note.. when I was at begginig playing with settings I didn´t backup the betaflight and accidently restore default settings,   so I copy settings from Joshua Bardwel. If anyone have settings backup can you share it with me ? 

And it is normal that VTX board Mamba is going extremly hot when connectedt to PC and battery ?

Plan B is to buy R-XSR and Radiomaster TX12 .. do you think it will work or any better alternative.. I would prefer smaller radio.

Thank you in advance... hope next time I will not have such a noob questions.

I can't really tell from you photo. Regardless, you need to solder the signal from receiver to RC pad on the FC. Select serial based receiver and not the SPI. Then select SBUS. Next on the port tab, toggle serial rx on UART 1.

If it still doesn't work, take a better photo of your wiring. Show wire from receiver to FC. And post a dump and diff all file.

Thank you for reply.. this is what I thought.. that will be needed different reciever. 

And is it normal that VTX board Mamba is going extremly hot when connectedt to PC and battery ?

Thank you 

Vtx gets hot. You always want to connect an antenna when you are bench testing.

Hello, got r-xsr and I am unable to bind with tx12 radiomaster. Any suggestion what to do?
