What's the big deal? The ailerons are on the right stick on the Giles. On the glider the rudder is on the right stick. Either way you use the right stick to turn. If the Giles is set up properly it will be a very honest plane. It will jut be a lot faster than the glider. In many ways sport models are easier than trainers because they do what you want them to and are very neutral. You just need to know what you want to do and have some eye-hand coordination. Chances are your friend pulled it off, but the question is how long until he crashes the Giles. His skills are probably far behind the plane and the first time he tries to bring it in to land at glider speed it will be dust.
