This is a set of two green K&B Dream Designs 60-90 Size Neon Tail Blades. K&B Dream Designs Helicopter tail blades are created using a complex combination of materials which provide the perfect mix of strength and flexibility. The blades have a very large surface area, yet weigh very little. The colorant is made to our specifications and is mixed as the blade is created. The color completely permiates the blade, and is not painted or applied. All similarly sized blades are the same weight, allowing the user to customize their tail rotor colors as desired. The 60-90 Size Tail Blades are 102mm long and weigh just 6g and can be used for most 60/90 size nitro or electric helicopters.
