Swashplate 5-blade, 12 Mm

The swashplate disc can be controlled by 4 ball-end bolts at 90° or by 3 ball-end bolts at 120°, whether the linkage is direct to the servos or utilises bellcranks. As standard there are 4 linkage points.
In both types the swashplate bolt assumes the additional function of one linkage point.
