NewSensored motor install going backwards

[Dandare]

A mate has just fitted a sensored brushless motor & ESC to his car & its runs backwards, All the A,B,C's are soldered correctly. I've read enough to know you can't solder these wires any differently. The ESC appears not to have a reverse direction option, these leaves reversing ch2 on the radio. But, wouldn't this mean brake settings will be working when going forwards, full throttle going backwards etc.

Is there another way of getting the motor to run in the correct direction ?
