25mm Dualsky Spinner for 3mm shafts

This 25mm spinner has 3mm hinge pins, making it suitable for our larger (8" plus) folding prop blades. However it does not fit most of the small 6" and 7" diameter blades that have holes for 2mm hinge pins.

This Dualsky FPS_25 Spinner is designed for 8mm root folding propeller blades and is suitable for electric gliders requiring a 25mm spinner. It comes with a beautifully machined alloy yoke (centre piece, hub) and hollow polished steel hinge pins for mounting the prop blades. A 3mm split collet securely clamps the FPS_25Z Folding Propeller Spinner assembly to the motor or gearbox shaft.

• Lightweight.
• High quality.
• Accurate CNC aluminium yoke ensures smooth operation.
• Cranked or Z yoke allows the prop blades to fold closer to the fuselage, reducing drag.
• Supplied with a tough white plastic spinner cone.
• Two front mounting screws supplied - smaller one allows cooling airflow through the spinner.
• Good value.
