Mixing
From RC Helicopter Wiki
Mixing is the combining of two or more control inputs to give one or more outputs. Mixing can be performed mechanically on the helicopter, or electronically either in the transmitter or on the helicopter.
Examples of mechanical mixing include:
- Mechanical CCPM mixing.
- The washout mixing out collective inputs from the swashplate movement.
- The Bell-Hiller mixer mixing together swashplate and flybar movement to change main blade pitch angle.
Examples of electronic mixing include:
- On-helicopter mixing:
- Rudder with gyro response in rate mode.
- Virtual flybar systems
- In transmitter mixing:
- Electronic CCPM mixing;
- Revolution mixing;
- Rudder to throttle mix;
Many programmable transmitters also have user-programmable mixes, which allow any amount of one input channel to be mixed with any other. This allows the user to define mixes such as a swashplate timing mix to fix poor swashplate timing, or a cyclic to throttle mix to maintain head speed through high cyclic pitch maneuvers.
