Helicopter AK1-3

The AK 1-3 power-plant is a 165 hp, fuel injected, Subaru EJ-25 derated at 156 hp. It is liquid cooled and was chosen for its reliability and excellent power to weight ratio. It uses premium (95) fuel.

Power from the engine is transmitted through a belt drive with overrunning clutch to the shaft of the main reducer. Minimal engine coverings make it easy to do a pre-flight check, and fluid levels are clearly visible through site glass.
