Model airplane, what is the throttle curve?

The purpose of the throttle curve is to change the linear throttle into a curve, thus providing different flight modes. We use the simplest three-point curve to illustrate that the accelerator lever of the launcher is divided into three points from the bottom, middle and top, and the corresponding throttle amount of an ordinary launcher is 0%, 50% and 100% respectively. If there is a transmitter with throttling curve, these three points can be set separately. For example, we set the bottom 0% to 100%. At this time, when the position of the throttle rocker is in the middle section, the throttle amount is 50%. Push the throttle lever up and down and increase the throttle amount continuously until 100% throttle. At this time, what we see is a V-shaped throttle curve (this is the throttle change requirement of 3D mode). A five-point curve is to insert two points between three points to provide a smooth setting closer to the curve. Of course, there are also some high-end remote controls that provide 7 or more set points. So how much is appropriate? In fact, more than 5 o'clock in world-class competitions is enough!
