O.S. MAX-46LA 2-Stroke Engine for Airplane (with Muffler)
The standard in sport engine technology, in a unique streamlined design.
Features:
- More cooling fin area extends the life of the engine, and virtually eliminates engine seizures in the air
- Added "webbing" on the crankcase strengthens high-stress areas to help ensure that they stand up to the rigors of learning to fly
- Overall tighter needle valve fit utilizes an "O" ring to help maintain the performance levels you need
- A fuel inlet that points up allows for easier fuel line access for fueling and defueling
