Hi everyone, recently I bought myself a first drone - meteor 75 pro, after some time it started to have motor stutters, which I could fix by replugging the motor, but I basically had to do it after every crash. So I decided to solder motors directly to the board.
After soldering the motors directly to the board I don't have stutters anymore, but now when I go above ~20% throttle I can't go back: I can't lower throttle, only increase it, so just flies straight up and crashes. This doesn't happen with pitching though.
As you can see by the picture, this was my first time soldering, so I am just glad that motors spin, but does anyone have any idea what might causing it?
Edit: Thank you all for your help! I'll get a practice board to learn how to properly solder and then try to resolder this AIO.
