38mm HyperSpinner Power for 3.17mm (1/8") shafts

Vladimir's Models HyperSpinner/HyperSpinner Power for 8mm root folding propeller blades, suitable for AVA-Pro, Supra, Sprite, Mini Graphite and all models requiring a 38mm spinner. The machined alloy yoke (centre piece) in this version has a centre boss to provide a better attachment to the motor shaft. Two polished steel hinge pins securely mount the prop blades and unlike other designs do not have stress raisers where the thread ends. Two grub screws are used to securely attach the assembly to the motor shaft.

These 38 mm spinners are currently being rebranded from Hyperspinner to Hyperspinner Power as they have a central boss similar to the other Power HyperSpinners. No actual change has been made to the design, and we will be selling them under both names until the old stock is exhausted.

• This 38 mm HyperSpinner yoke has a centre boss providing more metal adjacent to the motor shaft, allowing the spinner to be used in higher power application.
• The accurately CNC machined aluminium yoke ensures smooth operation and good power handling.
• The cranked yoke design allows the prop blades to fold closer to the fuselage than with a conventional design, reducing drag.
• Supplied with a tough black plastic spinner cone that absorbs hard landings without cracking.
• Other colour spinner cones available as spare parts.
• The spinner front hole reportedly allows "turbo" motor cooling, if suitable holes are drilled in the firewall.
• Supplied with an Allen key for easy fitting.
