motors don't spin up on 5S?

[Ryan Thomas]

I have just bought and installed some MT2814(similar to AVrotor) motors, these are 710kv not 770kv,

on 3s or 4s all motors start fine, on 5s or 6s I can't get all the motors to spin up? 1, 2 or even 6 spin up and it's never the same ones?

all work on 3S or 4S, and the roxxys i took off had no issues on 3,4,5 or 6s. Running BL1,2 with 25v caps to handle 5S or 6S,

anyone have an idea?

just had an idea, the motors came with 3 black wires so I have no idea which is which, I know we dealing with AC but would the order make a difference?

No, that only determines spin direction.
