O.S. MAX .25 LA RC Airplane Engine

Sparingly used in very good condition/ compression, not new in box.

The standard in sport engine technology, in a unique streamlined design

• 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
