The Weaver Aircraft Company (WACO) of Troy, Ohio built the best aircraft, building twice as many aircraft as any other manufacturer between World War I and World War II. The Waco UPF-7 was one of the most popular Waco models built, and is cherished as not just an avid aircraft collectors item, but a great, rugged working airplane today. Our Waco was one of more than 600 UPF-7 models built prior to and during WWII. A 1930's advertisement stated: Words can't express it... Pictures can't record it... Climb into a WACO. Give 'er the gun. Off and up with a roar and a mighty zoom. Man... What an Airplane! Lucky Lindy flew Wacos, Amelia flew Wacos, and now You can too.
