Since somebody was kind enough to catch me on this before, I'll share the following with you: Doc Matthews is a great designer, but the Whiz family came from the mind of Owen Campen. In this case, the good Doc was just the one who adapted it for manufacture in the appropriates sizes, etc.

We've currently got two Whiz .40s in our club and a group more on request. A really outstanding thing about the Whiz is the way it lifts its tail like a real airplane and taxis just as pretty as you please on the mains and rudder... and it doesn't nose over even on our rough grass field. Also a very fine flyer capable of all the stuff that doesn't require a purpose-designed aerobat.
