This is the same brushless whoop I was having problems with before. I took all the motor wires off and soldered them again and they all seem to have a good connection. Is there some way I can test to see if it's the motors or the 4 in 1 esc? I know I can take the motors off and swap them but I didnt know if there was a way to do it with a multimeter. Does anyone have any other ideas on what this can be? I have flashed the esc several times and it flashed properly. I have the esc set to dshot 600 and I tried 300 as well. It's the teeny 1s stack by happy model and is dshot 600 compatible. Thx for any help!
