We are pleased to announce we finally have the complete range of Vladimir's Models HyperSpinners in stock. These are available in 30mm, 32mm and 38mm diameters, with holes for motor shafts from 3mm to 6mm diameter.
See www.hyperflight.co.uk/products.asp?cat=Hyperflight+R%2FC+electric+%26+gl iders&subcat=Spinners
All have "cranked yokes" to help the blades fold closer to the fuselage, reducing drag.
The 30mm and 32mm units are available untwisted, and with +3 degree twist. The 38 spinners are available untwisted, and with +3.5 degree twist and +7 degree twist. Using a twisted yoke increases the effective pitch of the prop, always increasing the pitch speed, gives more pitch options, and often increases powertrain efficiency as the prop gets nearer to the ideal "square" configuration with a pitch equal to the diameter.
You can use this Google Spreadsheet to calculate the new pitch when using a twisted hub.

To encourage people to try these spinners we are have an introductory offer of £3 off all twisted yoke spinner orders, until the end of June. Just enter the text HYPSPINNER1 in the Voucher field when checking out. Untwisted spinners start from £13.45, and twisted ones start at £15.95. US delivery is £3.95, and the USD-GBP exchange rate is about 1.61 currently.
If you have any questions please ask.
Thanks for your time.
Neil.
