Making HELICOPTER Selection Options
Choose the HELI Swashplate Type that suits your helicopter. There are three basic Swashplate Types available:
Normal - In this conguration the swashplate does not control pitch. It only controls right, left, fore, and aft cyclic. Usually the
servos are installed 90º apart but do not mix with collective to control pitch. This conguration is generally used for xed-pitch
helicopters or helicopters that have a completely separate control system to control collective pitch.
3-Point CCPM - In this conguration the cyclic and collective controls are mixed. The servos that control the swashplate are
installed either 120º to 140º apart, depending on the conguration.
4-Point CCPM - In this conguration the cyclic and collective controls are mixed. The servos that control the swashplate are
installed 90º apart. A total of three or four servos can be used, depending on the conguration.

matches exactly the Swashplate Type used by your helicopter. Refer to your helicopter's Operating Manual for more information.
The following Swashplate Types are available for Model Type HELI. The
diagrams display the swashplate geometry, the number of servos used, and the specic placement of those servos.
120º, 90º, and 1:1* refers to the
physical relationship and geometry
of the servo placements on the swashplate.
