Sport planes like the Skyray, 20-25 powered Streaks, Busters, Shoestrings, and the like, feel easy to fly. Why? Many reasons I guess. They're simple to tune and trim. No flaps, no complicated sophisticated big bucks engine, no $50 dollar pitch adjust prop, a weight box (sometimes), adjustable leadouts that usually work in the stock plan position and so on. Easy stuff. When built straight they zip along a bit fast (for a stunter), stay out on the lines, and (again, if straight) turn inside, outside, evenly. Confidence inspiring. I like doing the shapes with a jr. Streak powered by an FP15 needled to shreeking. A pocket rocket version of the full sized sports. A friend did a similar fun exercise with a jr. Magician powered by an equally abused LA15. Even these overpowered versions of the idea look like they're doing a decent corner, if you can do your part, fast. Wind. Weird wind changing direction. What wind. Among other things, I never saw one of these birds, full sized or shrunk, fast or moderately fast, hinge. I hate hinging. I never had (again, if built straight, controls free etc.) a difficult to diagnose and/or fix inside/outside turn rate differential. Flapped full bodied stunters that exhibit inside/outside turn rate issues mean... even when you've built in access to the elevator adjustment... this can be maddening to fix. Right. Engine and tank are out there in the breeze in a profile. Any problem, pop the rubber bands, undo the screws, or equivalent, replace or fix tank or engine. Obviously we've access to control horn ratios. I agree with Brett on this, our complicated stunt war wagons take a great deal more work, experience and expertise, to gain the potential edge. I have had more than a few of these birds be an enduring frustration. Never performing, even in contests, at a level equal to my best profile. Happened this past season. I wound up flying a modified Magician 35 as opposed to a Vector for points. The plane flew better and was way easier to tune and fly. My scores (modest as they are) were higher flying the Magish.
