40LA Sport

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.
  
  
• Coarser threads on the remote needle valve makes engine tuning easier and safer.
  
  
• 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.
