This is a pair of 325mm Curtis Youngblood Radix rotor blades. Radix blades fly light and quick for agressive 3D but they still do forward flight like they are on rails. In addition to their smooth precise flight characteristics they are also one of the quietest blades in the air. To top it off they auto great. The perfect combination for a 3D blade.

   * Washers included in lid of box; (2) 0.25" & (2) 0.15".
   * All blade sets are pre-balanced and ready to fly.
