Included accessories
Delivered with standard engine package:

  • The engine with integrated alternator, water pump, oil pump and electric starter.
  • Rubber mounts (dimensions same as Jabiru and UL power)
  • Fuel pump, fuel filter and injectors
  • 2 ignition coils, spark plugs and ignition leads
  • ECU and loom (standard redundant injection)
  • 3 water temperature sensors (2 for ECU and one for instrument)
  • Oil pressure and oil temperature sensor
  • Oil radiator, oil filter, oil tank with breather system and hose + connectors
  • Exhaust pipes included and lambda probe.
  • The liquid cooling system (radiator, hoses and expansion tank) are not included.
The different aircraft and helicopters, equipped, required different cooling configurations. It is too difficult to anticipate a solution for every installation. Attempting to provide a universal solution would be both inefficient and overly expensive.

The weight of the engine completely installed with liquids is 85 and 88 kg depending on installation. This weight does not include the engine mount or propeller.

The actual TBO time is 1500 hours.

Options:

  • Plywood crate (FAO-IPPC-ISPM15), packaging and handling
Warranty: 2 year
