What are pitch / throttle curves, there are no curves in my radio?
A helicopter radio allows you to setup a pitch and throttle curve. A good radio will have 5 points of adjustment. These points represent five positions of the stick, bottom, 1/4, 1/2, 3/4, and top. For each of these stick positions you can set a value. This value ranges from 0% to 100% and for the throttle represents the percentage the carb is open. For the pitch, 0% represents the minimum pitch and 100% is the maximum pitch. The radio lets you set two or more sets of curves for the throttle and pitch. They are selected by flipping the flight mode and throttle hold switches. The term ‘curve’ just refers to the shape of the servo output line if you plotted it on a graph… okay I know that’s confusing. Only a few of the high end radios actually display a graph showing the curves. Most radios, including both of mine, only show you five numbers for throttle and pitch settings. These numbers can be used to draw a graph. For example, take a throttle setting of 100,78,63,78,100 (this would b
