The new Raptor 90 3D was created for the 3D aficionados. Taking the proven Raptor 90 SE as the foundation and using only the essential parts for extreme 3D flying. Then to save weight they stripped all items that are unnecessary for extreme 3D flying, and added the must-have options that are necessary for 3D. Added the must-have options for 3D, at lower cost. The CNC machined aluminum rotor hub and 30 grams weight paddles with large control surface area and a thick airfoil makes a lightening fast cyclic response and rock solid hover. With three different Bell-Hiller mixing ratios offer the pilots a choice of agile, very agile and extremely agile control responses. The Raptor 90 3D is what you need for all-out 3D flying at a minimal investment. Features Machined metal main rotor hub New nonlinear stiffness flapping damper Machined metal bearing blocks for main rotor shaft Aluminum seesaw that permits three different Bell-Hiller mixing ratios Bell-Hiller mixing arms with holes for different control sensitivities Light weight 30 grams Hiller control paddles for 3D flying Push/Pull system for collective, roll cyclic and foward/after cyclic control Machined metal foward/after cyclic control lever Carbon graphite 3D vertical fin Light weight tail boom bracket for attaching tail boom support 8.27 to 1 gear ratio for 3D flying (91T main gear and 11T pinion)
