Ive had that happen to me with of all things an LT 40... My answer to this phenom was to listen to a master builders advise and make the top and bottom surfaces as contrasting as possible. my solution involved starburst white and red design on top wing and elevator and then two large white diamonds on the bottom of the wing. Another one of our club members used 4 inch red Dots on the entire underside of the plane and starburst on top of wing , tail and rudder. Really makes the difference.
