My 12020 Has Gone Crazy (help!!!)

[ANGRY-ALIEN]

As the title has suggests, I am having some issues with a BK Warrior 12020...
I recently put together my first brushless system with with a Fiegao 8xl and the BK 12020 combo.
The truck (an emaxx) ran really well and I was having quite a bit of fun with it...
Trying to find even better results with power output, I played with Two different pinions, a 18 tooth and a 20 tooth.

One night I did some tests on asphalt just to see what kind of torque I was getting.. I squeezed a little hard on the throttle and the truck went from wheels to roof in a split sec.. But there was no roof really, as I was doing the test without the body mounted.. The truck landed on the heatsink attached to the motor and crushed some of the fins .. The motor did not spin the first time I squeezed throttle... then I notice the Motor plate was bent. when I removed the motor and "straightened" the plate, the truck work again... A few days later... it stopped again. I tried to re-programme the BK... When I ran it, It got very hot and refused to spool up... It just cogged like crazy..

My first thought was the motor was damaged.. I noticed that the bearings had quite a bit of play in them, so I ordered a new pair... but when I tested again... It did the same... So i ordered a new motor and installed it tonight, but to my disappointment, it did not work... So now my attention has been drawn the BK controller...

Has anyone had this experience before? And does anyone have any suggestions? The biggest problem I have now is that I live in Jamaica.. They are no hobby stores here, so i have to ship everything I need to the island (this is a real pain)..

Any help will be appreciated.....
