Description
OS MAX AX 2-stroke engines are the latest range of powerful power units designed primarily for sport and aerobatic models. The meticulous construction features a unique ABL insert (Advanced Bimetallic Liner) with a two-layer surface treatment of specially developed alloys to minimize friction and wear during operation, ensuring high performance and long life. The futuristically shaped hexagonal cylinder head with large cooling fins offers excellent cooling and enables higher performance with the same dimensions as the classic FX series. Thanks to this, you can take advantage of the wide range of kits and model plans developed for OS MAX 2-stroke engines over the last few decades, or obtain a performance boost for your existing FX engine model!
