First, the reason:
1, flying slowly will have a movie effect, giving the audience a feeling, just like shooting a tall plane and a helicopter with professional equipment. Flying slowly can make drones more controllable. Especially single-person drones.
2. Move the remote control lever as little as possible to make the movement of the drone smooth, so that the drone can slow down when accelerating and decelerating. Otherwise, the lens will have obvious frustration, which will increase the probability of lens deformation and jelly effect.
Second, the method to slow down the moving speed of UAV:
Increase the length of the rocker. As we all know, the control input of UAV is directly proportional to the change of rocker angle. Increasing the length of the rocker can unconsciously increase the number of finger movements. Under the condition of the same finger movement distance, the angle change is small and the input quantity is also reduced.
