Mudry CAP-21
The CAP 21 arrived in 1980 as Auguste Mudry's answer to the handling shortcomings of the earlier CAP 20 series, fitted with a new, more advanced aerofoil wing section and redesigned landing gear to sharpen its competition performance. Only 18 were built, powered by the same 200-horsepower Lycoming AEIO-360 as its predecessors, with some later retrofitted to 260 horsepower. Rather than being an end in itself, the CAP 21 proved to be a stepping stone: its airframe became the direct basis for the CAP 230, strengthened to take a bigger 300-horsepower engine and go on to win world aerobatic titles.
