38mm HyperSpinner for 5mm shafts +7º twist

38mm HyperSpinner for 5mm shafts +7º twist

Vladimir's Models Twisted Hyperspinner for 8mm root folding propeller blades, suitable for AVA-Pro, Supra, Sprite, Mini Graphite and all models requiring a 38mm spinner. Comes with a machined alloy twisted yoke (+7º) to increase the prop pitch, and polished steel hinge pins for mounting the prop blades. Two grub screws are used to securely attach the assembly to the motor shaft.

• 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.
• The 7º of extra pitch given to the propeller blades increases their effective pitch, allowing props with a greater pitch/diameter ratio, for higher efficiency and power transmission.
• 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.
