I've looked over the JetMach series extensively. I like them, but I also like the option of a simple flyer. No retracts to deal with, minimal brakes (required under AMA), simple, slow speed design that can utilize lower priced servos (HS645MGs come to mind). If I can't find what I'm looking for, I'll have one cut. I've drawn up a similar design to Hal's. It's sort of a cross between Hal's, Jim Fox's FoxJet, a Reaction 54, and a FoxCub. But, I'd rather just buy a kit and get to building.
