About Jack Rosen

Built my first car when I was 15, using a Singer chassis, and a Ford V860 engine. Have raced cars, iceboats, bicycles, and sailboats. I compete in aerobatics with a plane I built called the One Design which is capable of competing in the Unlimited class(I'm not). We also compete with our Cobra and Formula Continental. We have a current SCCA racing license. Haven't quite decided yet how serious we'll get on the track with the Ultima. Thank you for viewing our website. Jack
