Carbon GT broken again (4th time) Yay.

Hey guys,

Boards broken again, 3/4 of the times it's resulted in this issue.

Right motor won't accelerate but brakes/ braking causes the broken motor to stutter making it pretty impossible to stop from anything over 10kmh without throwing me off.

I've taken the board apart and there is a green flashing light on the Control Unit, I've swapped the broken motor off with a good one and the green light is still there.

My question is what is the green light for and anyone else had this error or similar?
