Features: Improved rotorhead assembly containing several strategically placed metal components. High quality, anodized and clear coated metal components which add strength and durability. These metal components also provide increased strength with added resilience to withstand those unforeseen impacts. Strategically spaced frames provide a light yet rigid design resulting in enhanced performance. Carbon fiber frames reduce weight and improve rigidity which result in less flex and quicker response times when performing 3D maneuvers. Addtion of a constant driven tail helps with autorotation. New control system allowing rotor blades up to 550mm Carbon fiber battery support, vertical and horizontal fins increase rigidity and strength for added durability.
