overall maneuverability Some ways counter decreased maneuver ability increase control surface area surface deflection flight speedall practical limits course com bination have maximum practical deflection using scale areas flying 10-in diameter 6-in pitch prop resulting good low-speed control low throttle settings offering reasonable high-speed flight full throttle addition flaps both
