O.S. Engine OSMG1951 50SX-H Ringed Hyper Helicopter Power Unit  [OSMG1951]

Performance tuned O.S. Engine OSMG1951 50SX-H for sport helis

Serious RC helicopter pilots looking for compact power will appreciate the O.S. Engine OSMG1951 50SX-H Ringed Hyper. It is engineered to give improved horsepower while keeping weight down, helping models accelerate and hover more effectively.

More power without the weight penalty

The Ringed Hyper steps up output compared to the earlier 50SX-H but avoids added bulk, allowing higher rotor RPM and livelier flight behaviour. Its dimensions fit typical .30-size mounts for straightforward replacement or upgrade.

Upgraded carburetion for cleaner throttle response

With the larger-bore 60LH carburetor (1.5 mm increase), the engine widens usable power and refines throttle transitions. Expect a reliable practical RPM spread of 2,000-20,000 for various flying styles.

The O.S. Engine 50SX-H Ringed Hyper is a good match for pilots seeking agile mid-size performance and is a straightforward option for replacing a .30-size engine.
