I happened upon a NIB Dazzler kit recently, and when I read up on the threads for Dazzler and Uproars, it does not appear anyone uses a four-stroke in theirs- Why? I have a Magnum .46 and a .52 FS, both weigh the same (the .46 is a little heavier by about an ounce or two), similar performance (.46 2-stroke will probably have an edge in umph). With the plane limited on fuel tank capacity, it seems more would use a four-stroke for better "milage" of less fuel used. Just wondering if anyone has a four-stroke in theirs, or if there is a solid reason everyone is using a 2-stroke in this plane.
