RotorTech™ Standard Features:

• Safety wire runs alone the inner core of the blade. This keeps the blades in one piece upon a crash to insure safety to pilots and bystanders.
• Low parasitic drag coeficient due to the efficient airfoil and top quality clear resin finish, insures more engine power is transferred for lift, speed and more crisp maneuvers.
• High density D-Spar of Carbon Fiber mixed with a special resin absorbs all high-g spanwise loading.
• Designed for your 3D performance.
• Mathced C.C.G. for stability.
• Matched outward S.C.G. for better autos.
• Airfoil designed for fast, accurate cyclic.
• Layered for optimum aerodynamic damping.
