Engineering FAQ

  •  Toray 2511 carbon prepreg.

  • Approximately 50 precision-molded composite components engineered for consistent assembly.

  • Prepreg carbon offers a superior strength-to-weight ratio, corrosion resistance, and the ability to form complex aerodynamic and structural shapes. Using a limited set (50) of precision molds reduces assembly variability, lowers part count, and simplifies kit build steps for the amateur constructor while maintaining high structural integrity.

  • Turbotech TP‑R90 recuperated turbine (141 HP).

  • Recuperation improves thermal efficiency and lowers specific fuel consumption versus a non‑recuperated turbine, giving strong power for weight while stretching range and endurance.

  • Custom 44‑gallon Fuel Safe tank

  • Roughly 5 hours of flight time enabling extended cross‑country capability.

  • With the TP-R90 and recuperator installed, the aircraft’s fuel burn is approximately 9 gallons per hour in typical cruise conditions.

  • The Vixen uses carbon-fiber rotor blades from Duke Propellers.

  • The main rotor operates at 450 RPM, while the tail rotor operates at 3000 RPM.
