Lightweight Rotary Engine O.S. Engine OSMG1401 49-PI Type II .30 Wankel Rotary Engine  [OSMG1401]

Small Rotary Engine Built for Smooth Throttle Response

The O.S. Engine 49-PI Type II .30 Wankel Rotary Engine brings smooth, compact power into light airframes. Its rotary mechanism and quality bearings reduce vibration, making the unit easy to live with on small sport models and good for pilots refining their throttle skills.

How the Rotary Layout Helps

The Wankel concept removes many reciprocating parts found in piston engines, which lowers mechanical vibration and noise. Needle and ball bearings support the rotor, improving balance and reliability for regular flying sessions.

Performance Range and Practical Use

Rated at 0.30 cu in (4.97 cc) with an output of 1.27 hp at 17,000 rpm, the engine offers a practical rpm band from 2,500 to 18,000. That spread works well for gentle cruising as well as tighter aerobatic moves when paired with the right prop.

Mounting Flexibility and Intake Design

The muffler can be rotated to suit different cowling and tailpipe layouts, giving installers options for neat finishes. The Venturi intake improves airflow into the carburetor so the engine responds cleanly across the throttle range.

For builders wanting a space-saving motor with refined running character, the O.S. Engine 49-PI Type II .30 Wankel Rotary Engine is a pragmatic choice. Its adaptable fitting options and steady power suit many light model applications.
