The Scimitar Series has a name change and is now the S-2 Series. The design still feature the same narrow, swept-back blade profile and undercambered blades for high thrust and lower noise. The S-2 is the second generation - the molds have ben redone for better balance, nicer parting lines and less flash. Not only that - we've added 11 new sizes, inluding the long-awaited 9x4, 14x6 and 7x6. We've also added an 11x4, 15x6, 15x8, 16x6 and 16x8. They are made of charcoal gray glass-filled nylon.
