  • Appearances are deceiving. In the world of automobile design, for example, it's common to introduce a supposedly fresh model that is really a new body atop the old platform — giving what seems to be a clean-sheet design that in fact shares engine, suspension, and other major components with the outgoing version. It's a time-honored way to add sizzle to a well-aged steak. But just the opposite is true regarding Diamond Aircraft's latest version of the two-place Katana trainer, the DA20-C1. It's grown the C1 suffix as a result of a 125-horsepower Continental IO-240-B under the cowling that drives a fixed-pitch propeller. Even when you know that fact, a casual examination of the C1 barely discloses the differences from its predecessor, the Rotax-powered A1. A wasp-waisted empennage still draws the eye, as do the bubble canopy; sailplane-like T-tail; and long, graceful wing.
