Weird problems HPI flux Blur ESC (MM2)

[Jarno1997]

I know, thats why I think the problem is somewhere between the ESC and the motor. The bullets on the motor look just fine. I think the ESC is the problem, but I don't have a spare Mamba Monster to test it. Does someone have an idea to determine if it's the ESC or the motor that's malfunctioning?

I think I'm going to open the ESC up and check the soldering on the bullets.
