HV Maxx problem
 

I have HV maxx brushless system 6.5 in my Losi8 buggy.
The problem is blue and green light blinking when I push the trigger.
I've checked the drivetrain and motor, it's not locked/binding.
If I move the car back and forth a little, sometimes the motor can run but slow, sometimes it doesn't run at all.

Thanks,
