The Traxxas fuel is known for being a bit high on the oil content and not offering as much performance as other brands. I'm willing to bet it's just excess oil that wasn't burned off while running.I noticed some liquid coming out of the engine where the exhaust pipe connects to it, it had the color of rusty water but it was definitely some kind of oil the way it stained the plastic on my ez start.
