OK, I just pulled the motor, and looked inside. It's definately a broken connecting rod. I'm gonna be trading it in, although I have my eye on .18 HPI outlaw engine. Are these pretty good?

Quick question, the stock T-15 engine mounted directly on the chassis plate. If I get the G3.0, or the Outlaw engine from an MT2 SS, will I need to get motor mounts, or do they bolt up to the chassis too? Thanks for your help.
