RE: Improper break-in
I just finished doing a proper break in. The engine got a lot less hot this time, and the oil from the exhaust was clearer than when it was improperly broken in. It seemed to perform ok. As it ran out of nitro, the last second it ran, the rpms peaked and then it stoped. Is suppose this is normal. Is the fact that the oil the first time was darker and with some trails of dark brown and the engine was considerably hotter, a bad sign?
