The Embryo-Sport was derived form one of the first models we built when returning to modeling in the early 1990's after many years. The well worn plan we used as a staring point had no name or date so the linage is a mystery. The BMJR kit is intended for the Flying Aces Club Embryo Endurance event, but is flown mostly just for Sport, as it's name implies. It has proven itself as a consistent performer with very predictable flight behavior. Both our prototype and first kit built model, covered in Japanese tissue, weigh 23 grams ready to fly. Wing Span 17 1/2", Area is 50 sq. in. Kit id cocmplete with rubber mmotor and Japaneese tissue covering.
