RotorTech 420mm "Ultimate" Flybarless Main Blade Set - Goblin 420 / RAW 420

  • Incredible "iridescent" paint scheme, these blades offer a unique, new look in the sky depending on where the sun may be at any given time.
  • Excellent stability, high collective lift, a very late stalling point, and Crisp agility are features of the Brand New Ultimate blade technology!
  • Use for: Designed specifically for the SAB RAW 420.
  • The RotorTech 420mm Ultimate variant for the RAW 420 delivers increased performance across all metrics compared to all other blades in this category. At 40.5mm chord width, we see improved thrust at equivalent collective pitch angles, higher efficiency for longer flight times with improved performance, higher rotational (flip/roll) rates while maintaining stability and a linear feel, and an increased stall margin at comparable thrust levels. Auto rotations are improved greatly as well.


Compared to the current blades in this class, the RT-420U delivers the following qualities:

  • 10% increase in rotor thrust at same collective pitch angles
  • 15-20% increased flight times with increased flight performance!
  • 15% increased rotational rates without sacrificing stability or linearity.
  • 25% increased blade stall margin at comparable thrust levels.
  • Vastly improved low RPM and autorotation performance.
  • Significantly improved audio signature.
  • All RotorTech blades are precision balanced, and matched at the factory, allowing pilots to bolt on and fly any set of RotorTech blades (mains or tails) to their helicopter and fly right away!
