OS LA .40

The new 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
  • The .40 LA is also available in natural gray color
