O.S. Engine OSMG0982 81FS-a Aerobatic 4-Stroke Pumped Engine  [OSMG0982]

Trusted Power for Aerobatic Models

For pilots who need dependable performance from their aircraft engines, the O.S. Engine 81FS-a with model number OSMG0982 is a reliable option. Fitted with the PD-08 fuel pump, it keeps fuel delivery stable through aggressive maneuvers and rapid attitude changes.

Benefits for Aerobatic Pilots

The PD-08 pump makes a real difference by maintaining fuel pressure regardless of orientation. That steady feed supports consistent throttle response, which is important during complex aerobatic sequences.

Cleaner Running with Internal Recirculation

The 81FS-a uses a recirculation lubrication system so oil is cycled internally rather than vented out. This reduces oil deposits on airframes and makes post-flight clean up quicker for scale and sport models.

The O.S. Engine 81FS-a suits pilots who value consistent throttle feel and lower maintenance from reduced oil blow-by.
