I'm finishing up my first build and am in the testing phase. While testing the motors in the motors tab in betaflight to see what direction they were spinning, motors 3 and 4 spun at the same time. When I moved the throttle for motor 3, both 3 and 4 spun  and the same when I would move the throttle for motors. I then went into the BLheli configurator to set up my ESCs to see if that had any affect and when I changed the direction for ESC 3 it automatically changed  it to match ESC 4. I am fairly new so I'm still learning whats what. Any insight and help would be much appreciated.
These are my components:
EMax 2205 2600 kv motors
30a BLHeli_S Racestar ESCs
x racer f303 v3.1 FC


Cheers!

Hm could be an unintended solder connection on the fc. Did you solder the motor pins yourself?

But i also seen faulty boards like that before.

Yep, that was it. I did solder the motor pins and there was the tiniest connection between signal pins on the 3 and 4 motor connectors. Thanks!
