FSX Corben Baby Ace On Skis. The Ace Baby Ace was the world's first aircraft to be marketed as a homebuilt aircraft when its plans were offered for sale in 1929. Plans are still available and Baby Aces are still being built today. Orland Corben designed a series of aircraft for the Ace Aircraft Manufacturing Company, the Baby Ace, Junior Ace, and Super Ace. Corben's name was associated with the aircraft, and it is commonly known as the Corben Baby Ace. Thanks to Robert Kerr for the use of his gauges from "Pete". By Craig Richardson.
