I've only owned 2 engines so far. The .18 that comes with the Yok GT4rtr and the OS 12tr that i just recently bought. I broke in my new engine using basically the same method Pops suggested and it runs great. I've always heard that you have to properly break in your engine. This "drive it like you stole it" method is something totally new; i've never heard of this.
Can some other experienced veterans chime in on this issue and clear things up? I'm confused now.
