Mini 3 Motor/Engine Trouble

[rapha1909]

The back Left Motor on my Mini 3 is turning faster/harder then the others after i put on new propellers. I tried switching the old ones back but it didnt fix it.

If that is what is happening,(very strange) Are you using a prop tach? Its not a motor issue its an ESC issue. You need to replace the ESC Board. but be sure about it (sounds strange) check that the props are correct and in the correct place. (cw/ccw)

And how do you determine that... does your drone flip over when you try to take off?

Have you made sure that you have attached all prop blades correctly & on the correct motor?
