PULSODYNETM miniature jet engines
      will meet or exceed the competition -

  1. Design -

    • NO mechanical valve means virtually zero maintenance
    • Easy starting with compressed air
    • 'Racer'TM series - light weight, low drag
    • 'Scaler'TM series - cool outer shell, even in static running
    • Easy mounting in your model vehicle
    • High efficiency at flight / running speed
    • 'Racer'TM series - highest thrust-to-weight ratio at racing speeds

  2. Performance -

    • Thrust and efficiency INCREASE with airspeed after launch
    • Higher thrust-to-weight ratio than any piston or turbojet engine
    • Higher thrust-to-weight ratio at speed than any competing pulsejet engine
    • Efficient, lean burning operation with gasoline, automotive starting fluid or jet racing fuel
    • Vibration-free operation

  3. Safety -

    • 'Scaler'TM series - cool outer shell simplifies full enclosure in your model with greatly reduced fire hazard
