The SparrowHawk originated from the Windigo, a 44" span aerobatic sailplane designed by Pete Roehling (Model Builder magazine plan # 6842). The original Windigo was designed around micro servos and a 250mAh battery. Initial design changes were done to accommodate a standard 500 mAh battery, standard aileron servo and a micro elevator servo (In those days I just couldn't afford all that fancy micro radio gear).
