Channel 6 is most commonly used to control one aileron in a dual setup driven by a transmitter mix. This is of course, a proportional application. It may also be used as the flap channel, often with a three position switch for control, but sometimes with a rotary pot or slider. Many transmitters with seven or more channels have continuously variable (proportional) controls ( the JR 9503, for example, has a slider on each side).
