Saying that the only thing a radio control helicopter can do is move is a total ignorance. Some people wonder if there must be a strong current of air? : Yes! The aircraft would be based, although it was still, to the ground. What is clear is that no matter who moves and who is still, as what matters is that a move in relation to the other. Updates and things, imagine him on a radio control helicopter with the gyro so that they could turn for moving into the air, but also will create the corresponding lift and the plane can be suspended in the air without need to move it to the ground. And what is this? Neither more nor less than our beloved helicopter, an aircraft that holds constantly moving wings into the air, creating the lift necessary for to be suspended, without having to go to the ground. Second, what is the lift? We know why a wing creates lift. To make it simple and not get into radio control helicopter technical descriptions, parts of an experiment that most will be done once: Imagine sitting in the car, at a speed of 120 km eg / hour, and removing the hand out the window. Observe the behavior of the same for different positions: - The first hand will be completely flat and parallel to the ground and observe that it does not move neither up nor down and air resistance is minimal. If now he or she turns the palm of your hand just a few degrees up, watching the same, which tends to rise and we will also have to do more strength to hold it in position. The same thing happens but in the opposite direction when turning the palm down. - As we increase the angle of the hand, the upward shift is also greater and greater effort than we do to endure in that position. It is evident we will have an angle such that from it, all I get is to increase the air resistance without getting more lift. The higher yields will be achieved with angles around 0 degrees (plus, minus 12 degrees), where air resistance is still will be low and high lift. This is all about the top radio control helicopter functionality. Of course, external factors have to do with the final outcome! See how you can improve your own performance.
