OS MAX AX two-stroke engines are the latest series of powerful propulsion units designed mainly for sports and aerobatics models. The thoroughly worked construction has a unique ABL insert (Advanced Bimetallic Liner) With a two-layer surface treatment made of specially developed alloys to minimize friction and wear during operation and ensures high performance and long service life. The futuristic hexagonal cylinder head with large cooling fins provides excellent cooling and allows higher performance in the same dimensions as the classic FX series. Thanks to this, you can benefit from the wide range of kits and model plans developed in recent decades for two-stroke engines OS MAX, or achieve a performance increase for your existing model with FX engine!
