    Rotax 4 stroke

    Just watched a video of their plant. Shows that they use a press fit assembled crank shaft. So what type of bearings do they use for the connecting rod big end? I did a search and didn't turn up much on the subject. It looks like a not so great design for an aircraft engine, and others post that the engines are very costly items, too boot.
