Newly built drone has motor twitch

Hi everyone, complete newby here. I have recently built my first drone, however it has a terrible motor twitch and I just cannot solve the issue. My equipment is as follows: speedybee f405 v5, 04 air unit pro, xing 2 2207 2750kv motors and 4s batteries. Drone configured via betaflight.

I have played around with some settings suggested online but no change. I have gone through my motor solders and resoldered anything that I felt looked a bit off.

Any suggestions would be greatly appreciated.

Thanks
