IV. FLYING You should have a flight instructor teach you how to fly the Whisper. Like a real airplane, you must have an understanding of how to fly the model before launch, or you will probably not be successful. Check at your hobby shop or call the AMA (in the front of this book) for flying clubs in your area.
“sink”; heavy air in which your Whisper abnormally loses altitude. When you encounter sink, fly away from the area as soon as possible. In any event, don’t let your Whisper get too far down wind. If you do so, you may not be able to penetrate the wind adequately to get the airplane back.
