Instructions:
-Suitable for T-REX 500 series / 500 Scale Fuselage
-Following the release of multiple 500 class scale fuselages, we have introduced a highly scale 4-bladed main rotor head. The complete head assembly is constructed of CNC machined high strength alloy metal, and anodized for aesthetically pleasing appearance. The scale detail of this head assembly, when combined with our UH-60 Blackhawk or Hughes fuselages, results in scale quality never before seen in other similar products. Due to the flybarless construction of this rotor head, an electronic flybarless system is required for operation .
