The swashplate guide prevents the outer ring of the swashplate rotating; the swashplate pin runs in the slot in this guide. The part is fixed to the dome plate using M 3 socket-head cap screws.
The length of the swashplate guide slot allows generous collective pitch travels to be exploited to the full; its position on the rotor shaft can be adjusted to cater for smaller swashplates. Height of slot 55.7 mm
