O.S. Engine OSMG0678 140RX-P Low-RPM Pattern Engine  [OSMG0678]

High-Precision O.S. Engine 140RX-P for Pattern Models

Pilots who fly pattern routines will find the O.S. Engine 140RX-P engineered for predictable power and control. With 23 cc displacement delivering 3.5 hp, the engine supports steady, repeatable performance required for competition flying.

Torque at Lower Speeds and Robust Mounting

Designed to produce effective torque at lower engine speeds, the 140RX-P lets you fit larger propellers and lowers overall noise. Its reinforced beam mount and one-piece crankcase improve durability under the heavy loads of aerobatic manoeuvres.

Superior Fin Design for Stable Temperatures

Cooling fins that continue past the exhaust port enhance heat shedding, which helps keep the engine running consistently during long flights and in closed cowl designs.

The O.S. Engine 140RX-P is a dependable option for serious hobbyists who need a rugged engine capable of driving large pattern props and withstanding contest stresses.
