This is a pair of 690mm "Stick Banger" Radix main rotor blades from Curtis Youngblood Enterprises. Radix blades fly light and quick for aggressive 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.

These 690mm blades are lighter than most 690mm blades so will have improved cyclic response combined with excellent autos.


  • All blade sets are pre-balanced and ready to fly.
  • Individual blades are matched and balanced into sets. The normal weight variation between sets +-3g.
