I also had a MT, and I too turned it into a "RB" (racing buggy). Except mine was all graphite and I sold it because I thought the glitching was the car's fault, but after I opened up the ESC, I found out why it was so...

The MT2 however, may have a sturdier drivetrain, but it is not bulletproof. The 8s I had in it nuked my rear diff...twice.
