LA Series

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
15, 40 & 46LA are also available in natural gray color (OSMG0016, OSMG0041, OSMG0047)
All, except OSMG0040, include a glow plug
