High/low differences: High winged trainers have what is called self correcting ability. In other words if you are in a hard turn and you let go of the stick the plane will level out by itself. High wing trainers usually have a flat bottom wing which provides lots of lift. This means that the plane is capable of landing at slow speeds. But if needed, hit the throttle and the plane will start to gain altitude. This factor acts as a good safety feature. The high wing planes are easier to see from the ground because of the fusleage hanging below the wing. Low wing planes are more of whats called point and shoot. In other words if you put the plane into a turn and then let go of the stick, the plane will stay at an angle in the turn. To get the plane out of the turn you have to move the stick in the opposite direction. In general the low wing planes also tend to fly a lot faster than high wing planes and will also turn much quicker. The higher speeds and quicker response times make things happen too fast for a new flyer to control or understand what is happening. TO fly safe you will need to fly at an RC club. Ask the hobby shop where they are and go visit them. A lot of clubs have trainers that you can try on a buddy box and see what its all about. You can download a free flight sim called FMS and try that alos. Don't buy G8 right now. Its fancy and looks cool but its very expensive. Liink to FMS included for you and a model from the sim. [8D]
