Most club designated instructors have several years of flying experience with many different types of planes. He knows what to look for to check the air worthiness of a plane before he starts the engine. He can also get any trainer airborne and trimmed out fairly easily. With his flying experience a trainer is fairly docile, slow, and easy to fly compared to high performance planes. This greatly reduces the chances of your trainer crashing during your learning stage. With your G2 experience you at least know what the sticks do and that is more than a lot of other newbies! BTW, most trainers don't crash until after a flyer passes his wings and gets too cocky trying fancy stunts. MY LT40 never had a crash during my training, then my sons, and 3 of his friends before we sold the plane still in 1 piece.
