Electric Flight

摘要

Hi Fliers: I'm sure most of you have had a Flyzone or HobbyZone micro flyer that may have a worn out airframe and is just looking to be a donor for a new model. The Baby Biwinger is a complete balsa kit by Retro RC, LLC. I built one up recently and was able to fly up a storm at the spacious E-Fest venue in Champaign, Illinois. The Baby Biwinger spans 13 inches and has 64.5 square inches of wing area. All-up it should weigh between 1.3 and 1.9 ounces, giving a modest 2.9-4.2 ounces/square foot wing loading.
