Additional Details


No other form of aviation can equal the experience of flying open cockpit in helmet and goggles. The year was 1928 and the Baby Ace is introduced to the aspiring pilot of average means, by Orland G. Corben. The introduction of the Baby Ace comes well in advance of the likes of Cessna, Piper, or even the EAA (Experimental Aircraft Association). This inexpensive, quick building, and easy to fly airplane is a helmet and goggle flyer’s delight.

December 7, 1941 – Japan bombs Pearl Harbor and the United States is at war with the Axis powers. The demand for pilots to serve in WWII shifts the consumers focus away from home building and a year later (1942) the Corben Sport Plane Company ceases operation.

After returning from Korea in 1953 EAA founder and homebuilt enthusiast Paul Poberenzy purchased the assets to the Corben Sport Plane Company and presents and updated Baby Ace Model C as a three-part build article in the 1955 Mechanix Illustrated. The article ignites a renewed interest in home-built aircraft and sets the stage for the founding of one of the worlds largest aviation organizations. Experimental aviation and the modern homebuilt movement explodes. Sources: Corben Sport Planes Museum. EAA

This quarters micro builder program model was inspired by these two great American aviation pioneers, and though they are no longer with us they have ignited a passion for flight in our wonder years that burns to this day.

Our version of the subject, Baby Ace UM, was developed as an approachable build project and is easily completed in several evenings by those entry level builders looking to give their first scale subject a try. The Baby Ace UM accepts popular micro electronics from ParkZone and E-Flite, and while other micro electronics packages can be retrofit we suggest outfitting the model as designed. The Baby Ace UM is controlled via three channels (Rudder/Elevator/Throttle) and is positively stable in both pitch and roll making it a suitable model for those in search of a relaxing model to pilot around the weed patch. Each Baby Ace UM micro indoor electric RC kit is thoughtfully manufactured in Colorado, U.S.A. from hand sorted AAA grade balsa sourced through state side mills and backed with a comprehensive hardware package, step-by-step photo illustrated instruction manual, and the best design know how in the kit manufacturing business. Stevens AeroModel is committed to your success in aeromodeling and we believe the Baby Ace UM to be an ideal entry into the world of scale micro indoor radio control. So grab your little ace, grand child, or neighbor and together build this delightful classic today. Build It!
