Hey guys, I bought these LittleBee ESCs. Is there any configuration needed or do I just solder the motors (swap 2 wires on two for ccw) and fly?

Love it when someone called Charpu asking question in Beginners section Just kidding!!
Generally that should be sufficient. Confirm motor direction before you put props. These are mutishot capable so select it if your FC supports it.
unless you want to use BLHeli to change it you can do that also.

Normally i reflash then through the FC immediately after installing with the latest blheli then set damped light and the min to 1040 and max to 1980.
Then set also the fc to the same in beta / clean flight. Finally check whether all of them are in synch with the others regarding their settings

I used them on a micro build with 3800KV motors - no problems. I left the default firmware (I think it was 14.6) and just changed motor timing to high and reversed the direction on two of my motors (as opposed to crossing the wires) They have flown great, motors are smooth and no desyncs.

Or if you don't care, you can just solder them in their places (swap the wires when needed) and fly, in 99% of the cases they will just work.
