Well my new FC has arrived and silly me for thinking it would be a case of plug and play…
So iv got my head round the fact iv got to do some of the dreaded soldering only to be faced with what looks like totally different wiring lay out.
Does this make sense to anyone 
And if that doesn’t sense then whats with the connectors being different sizes ??? 
You. Will. Solder.
Death, taxes and soldering. You can be sure of these things
Is the one your replacing the V2? If so it’s discontinued so you will need the V3 fc that it looks like you’ve got. They must have made a few changes
Yah changing from V2 to V3
But how the hell is a guy supposed to work out whats what ???
All the wiring diagrams are near the bottom of this page 
It has various rx configurations (take note of the different pads you need to solder depending on which rx you’re using). Plus digital camera wiring (again take note of which pads you need to link with solder). It also has the betaflight configuration for each set up too
What receiver are you using? Is it crossfire or sbus?
If it’s the one I was looking at, at the big meet hes using the full DJI FPV system so the VISA is the RX as hes using the DJI radio so its SBUS
OK cool so it should be this part you need to set up and link the pads circled in red with solder. Then set the uarts in betaflight as shown
Lift the tabs and swap them over. One is probably for the DJI air unit and the smaller one will be for the vista
Cheers buddy Iv just worked it out 
Im looking at soldering the wrong end 
,got to tag the wires to the vista, full strip down job now …
Surely the wires are already soldered to the vista? If you don’t want to do any soldering then just swap the connector just make sure you follow the wiring diagram and get the wires in the correct order?
The original board doesn’t use connectors Deano so he won’t have the pins as its all soldered to the board
Ahhh ok, so yeah time to de solder the vista and solder on the wires of the connector lol again making sure you double check the wires are in the correct order.
Also if you don’t own a smoke stopper I highly suggest you invest in one
May I suggest this one: VIFLY ShortSaver 2 | Drone Authority
At least once he has done it, it will be easier to take apart in the future
It’s being attacked by a giant octopus 
Was it faulty Howard or doing an upgrade?
Faulty but probably caused by user error.
Sorted now and skills upgraded !
