Products

Variable Pitch Propeller Hubs

Designed for ultralight aircraft, airboats, hovercrafts, and aerosleds. We manufacture variable-pitch propeller hubs with control systems for two to five blades, suitable for geared engines with power up to 400 hp.

  • Optimal Efficiency: Adjustable blade pitch for takeoff, climb, and cruise modes
  • Improved Takeoff: Higher thrust, shorter takeoff distance
  • Fuel Economy: Reduced fuel consumption, higher efficiency
  • Operational Flexibility: Compatible with various engines and blades

Belt Reduction Drives

For Honda L13, L15, D16, D17, K20, K24 engines conversions to air propeller use.

  • Low Noise Level: Quieter than gear reducers
  • Oil-Free Design: No oil checks or replacements required
  • Visual Wear Inspection: Easy belt condition monitoring
  • Easy Maintenance: Simple belt adjustment and replacement
  • Increased Center Distance: Flexible layout options
  • Enhanced Reliability: Belt failure does not damage components

Ground adjustable Six-Blade Hub

A modular hub system adaptable for multiple configurations.

  • Versatile Design: Supports 2, 3, 4, or 6 blades depending on performance needs
