The Plasma motors are simply rebadged Feigao motors.
I've burned up two Truck ESCs. The first was in a buggy on 5s LiFePO4 (16.5v) with the built-in BEC being used. Mtroniks replaced it for free. The second time it was in my MT2 with 4s2p A123 and an 8L, geared for about 60mph. When these ESCs blow, there's A LOT of smoke because that insulating material that makes it waterproof ends up melting.

I had that controller in my MBX5T and it was really good. I did some speed runs with it and overloaded the controller and it burned (My fault). The controller is great btw. Here are the videos:
