Yep....

A friend of mine that was new to the hobby bought the Evader ST, as tower has it aimed at beginners. It was supposed to be EVERYTHING he needed to go run.... in a roundabout way it was... The engine comes with an airfilter that is not oiled. The manual doesn't tell you ANYWHERE to oil it. The instructional video that it comes with doesn't tell you ANYWHERE within to oil it either.... If you are a newbie you aren't just BORN with the knowledge. Their manuals still, are unchanged. His engine sucked in mad dirt the first day and died after about 1.5 gallons... when his sleeve was shot, it acted the same as yours.
