🚁 CCPM (Cyclic/Collective Pitch Mixing)
A swashplate design where three servos spaced 120 degrees apart share the work of both collective and cyclic control, mixed electronically by the radio or flight controller.
Because the servos work as a team, they should be matched in speed and type, and the swashplate must be levelled at mid stick before you set anything else. The older alternative, with each servo doing one job through mechanical linkages, is called mCCPM.
