The O.S. Engine GT55 Gas Engine, carrying the model number OSMG1555, is built to deliver repeatable power and straightforward maintenance for model pilots who expect consistent results from their engine installation.
The GT55 uses a high count of deep, narrow fins on both the head and crankcase to aid heat dissipation during extended runs. Its one-piece crankcase reduces seam complexity and preserves internal alignments for reliable operation.
A front-mounted carburettor assists with cooling and helps keep fuel delivery consistent. Shorter standoffs create a firmer mount, reducing unwanted movement, while direct throttle and choke linkage attachment simplifies rigging.
The IG-01 Capacitive Discharge Ignition employs a microcomputer for smart spark advance and uses magnetic sensing for timing. It copes with wet plugs, offers quick starts and keeps standby current low for sensible field use.
The GT55 is well suited to seasoned modellers seeking a solid gas engine with modern ignition and a layout that supports reliable installation and serviceability.
