Hey guys, can you take a look at this picture please.
I'm still trying to figure out what's going wrong with my crossfire setup.
I checked some imgs of nanos over the web and it seems that a capacitor is missing on mine. I didn't find any image with my nano version, maybe they took that capacitor out of the board but it seems suspicious.

Can you compare to your own boards?
Thanks

I just checked all mine and there's a capacitor at that location on all of them. It sticks up quite high though compared to some of the other capacitors so it looks a bit precarious. I can see it being easily knocked off if you're not careful. The only difference is that mine say Nano 43 on them. I'm not sure if that is a batch number or a version number. The circuit layout on mine looks identical to yours.

I can't say for sure, but I don't think I knocked it off, I was really careful. Either way, if someone with 44 confirms this existence I maybe found the culprit for the malfunctioning and I will try to get some warranty on the receiver.
I think the 43 and 44 stands for the version because on the tbs manual they talk about an improvement from 42 to 43 that was remove labelling on the pcb because it was a direct ground connection and solder sticked to it really easily shorting the pins.

Thanks for the feedback Snow. It would be a relief to be this... even if I just lose the money for this board. I already placed a order for a new one. I'll also ask TBS for support on this.

edit: errors

The capacitor connects across two pins on that square IC chip which I believe is the RF chip. Unfortunately it looks like a proprietary IC because there is no identifier on it and the only number seems to be a serial number because that number is different on all of my Nano receivers. If they had used an off-the-shelf IC with an identifier on, we could have looked in the datasheet at the reference circuits to find out what that capacitor is used for, but unfortunately that doesn't seem to be an option.

Yes. It would also worth a try to fix it by knowing the capacitor characteristics if I can't replace it for a new one under warranty.

The problem is that you can't reliably measure the value of a capacitor in-circuit, so you need to desolder a known good one in order to check it's value. You can measure ESR in-circuit but that's not the same as capacitance. When you get your new Nano RX, if you're brave enough you could desolder that capacitor and measure it's value

Only if I want 2 dead nanos and less 80€ in my pocket Nah!
I'll pass

I would definitely try asking TBS support what the capacitor value is. They might actually surprise you and give you the info

I'll send them the picture to confirm if that's the problem or if this new version came without it (I don't think so). Of course I will ask for that info Meanwhile I will try to return it but I guess that will not happen unfortunately.

So my Nano version 44 has a component there where your is missing. Looks like a capacitor. You should write to TBS as Snow suggested. I have done it in the past for the exact same reasons and they gave me the information without question. 

Thanks for the picture voodoo. 

I opened a ticket with TBS, and sent them the picture on my post. They fast replied and that it is 0402 Cap 10uF. 
I'll try to sort this out with the vendor because I'm pretty sure that I didn't mess with that component, somehow my board came without it. It's quite a small component, a bit of heat and it will stick to the pads easily I guess, but I don't have the component and it's under warranty, I will try to use it.
I'll share how will this go.
