Flight Design C4 Expands Envelope

Work on conforming prototypes has begun as the manufacturer hopes to achieve certification next year.

The Flight Design C$ has completed about a dozen flights since its maiden jaunt on April 9, expanding weight and center-of-gravity envelope to establish the baseline stall speed at gross weight. The piston single has flown at 2,640 pounds, demonstrating a stall speed of less than 54 knots. More stability and performance testing are planned over the next few months. (Photo: Flight Design)
