Recall that German-based Flight Design had its own four-place airplane, the C4, in the works until it ran into financial trouble. At Aero, the reorganized company announced a rethink of the CTLS line and a new four-place project called the F4. The latter will be a CS 23-certified aircraft that's essentially a stretched version of the CTLS. Predictably, the powerplant will be Rotax's new 915 iS. Gross weight is set at 2420 pounds with performance in the 150- to 160-knot range. The price target is under $300,000.
