Trojan’s Unique Design

Home » Trojan’s Unique Design

The Trojan was designed to operate unsupported and from unprepared airfields. Let’s explore how the Trojan’s innovative designs overcome some of the general problems experience with other recreational gyrocopters.

The Fuselage

  • The frame - The Trojan’s frame is assembled with bolts, unlike the recreational frames which are welded together.  This means that if something in the frame needs to be replaced, just that specific part can be replaced and not the complete frame.  This eases maintenance and quickens turn-around times for repairs.
  • A bigger cockpit is always more comfortable with more manoeuvring space and bigger loading space.
  • An entrance step for easy access.
  • An integrated inspection step to have easy access to enable rotor inspections.
  • Bigger tail which ensures more stability

  • Large diameter 6-ply tyres
  • Nose wheel which are open enabling easier maintenance.
  • Rear wheel suspension enables operation from extremely rough strips. If you can drive a pick-up at 60km/h, we can operate the Trojan from there.
  • Rear wheels do not need mudguards. Due to the design and wheel placement, any stones or mud projected by the wheels clears the propeller.
  • The high ground clearance helps with rough terrain take-off and landing.
  • Small higher placed rear wheel allows a higher angle of attack with the landing.
  • Ventilated disc brakes, to provide more than required braking power.


  • The rotor blades have a longer cord line and are longer. They have a length 37ft and was tested to lift MAUW of 780kg with ease.
  • The hydraulic pre-rotator has lesser maintenance requirements and can spin the rotor to a higher RPM then the mechanical systems in use for smaller craft.
  • The control links has flexible shafts which has lower wear and requires less maintenance.

  • There are 3 big radiators, 2 for water and one for oil, each with a scoop to redirect airflow and ensure optimal flow and cooling.
  • Developed our own Engine Control Unit (ECU) software.  We have the ability to manipulate and improve the engine management system.
  • The Trojan is equipped with a 135L fuel tank
  • The fuel tank is design to have attachment points that can detach and not tear from the tank and rupture in an accident. This is a safety system.  Too many fires has started after an accident where the tank had release fuel.
  • The fuel system has a filtration system linked to the on-board warning system. This ensures that the pressure in the system is monitored at all times and the pilot can be notified in the event that the filters are clogging.
  • Oil scavenger pump. This is placed in the lubrication system to ensure that the oil system is pressurized from the initial turn of the engine.
  • External 12V power points to ease the distribution of power.
  • A Subaru 2.5 turbo engine rated to deliver 280 horse power is used.
