FQ-730 Aviation Engine

Horizontally opposed, 4-cylinder

The FQ-730 is an aviation-grade, air-cooled two-stroke engine with a horizontally opposed four-cylinder layout. Solid-state magneto ignition and premix lubrication deliver stable output under heavy load and in demanding conditions. Every engine is dynamometer-tested and flight-verified before delivery, backed by worldwide technical support.

Engineered for Demanding Environments

Horizontally opposed, air-cooled two-stroke layouts with CDI ignition and premix lubrication.

Forced air cooling

Aluminium cylinders with ceramic nickel-silicon hardened bore coating, built for sustained high-power operation.

Solid-state magneto ignition

CDI automatic-advance ignition with synchronized opposed-cylinder firing and automatic transition at 500 rpm.

Forged seven-piece crankshaft

High-strength yet lightweight, with optimized vibration damping for a long service life.

Wide speed range (2000–7500 rpm)

Balances low-speed torque with high-rpm power and suits a range of propellers.

Specifications

Every figure is dynamometer-verified to aviation-grade standards.
