Curved flight is to let the UAV fly along a curve. Generally, it is Z-shaped or S-shaped route flight. This flight mode is not only for fun, but also for training the operator to freely control the UAV, similar to the feeling of "violating common sense". Therefore, it is necessary to repeatedly practice the operation mode and feel the flight rules of the UAV.

Curved flight operation is certainly different from straight flight, and certainly more complex than straight flight. First of all, make sure that there are no obstacles or people on the flight route. Then after the UAV takes off, it starts to fly along the curve path. During flight, the throttle rocker is required to control the direction of the UAV, and the direction rocker is used to let the UAV start forward flight. In this way, the motion combination changes the curve flight path.

However, this is only a way of curvilinear flight. Because of the special structure of the four axes, another way is needed in curvilinear flight. In the previous curve flight, the direction of the nose is constantly changed, and this way is to use lateral flight to achieve the same curve flight of the nose. So we have a second way to practice curve flight: first, use the throttle rocker to control the height of the aircraft, keep the nose direction unchanged, and use the direction rocker to control the forward and lateral flight of the UAV. Step by step control can complete curvilinear flight with unchanged nose direction. When practicing flying in the forward direction, you can try to practice curvilinear flying in the backward direction. However, it should be noted that if you are not familiar with the direction control of the UAV, you'd better not practice first, and then practice when you are familiar with the control of the UAV flight mode, otherwise there will be some danger.
