It's a great idea to learn to fly a trainer kite for two reasons. First, a big kite can be strong enough to lift you up in the air and drag you around, so it's safer and more fun to get a feel for how to pilot a kite on a small trainer kite. Second, flying a trainer kite will help you develop better kite-flying skills and will help you learn much faster. Any good instructor will always start you on a trainer kite. However, even a trainer kite has enough power to pull you off your feet. Make sure you are well away from people, power lines, and other obstacles at all times.
