Product Description

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


  • Featuring an advanced photonic paint scheme, these blades display light-dependent color variations, exhibiting a unique visual spectrum depending on the sun's relative position.
  • This blade set introduces the innovative "Ultimate" technology, offering unparalleled stability, superior collective lift, an extended stalling point, and impressive agility.
  • Intended Application: Specifically engineered for the SAB RAW 420.
  • The RotorTech 420mm "Ultimate" variant, designed for the RAW 420, outperforms all competing blades in this category across all performance parameters. With a chord width of 40.5mm, it provides enhanced thrust at equivalent collective pitch angles, increased aerodynamic efficiency for extended flight durations, overall heightened performance, elevated rotational velocities (flip & roll rates) while preserving stability and a consistent feel, and finally a widened stall margin at comparable thrust levels. This new design significantly enhances autorotation capabilities as well.
  • Specifications can be found at the bottom of the page.


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!
