| This is the OS Max .61 FX ABL Engine with Muffler. This series of engines is great for sport, scale, and aerobatic aircraft. This engine comes with the O.S. Max Two Year Limited Warranty.
Features:
- 1-piece crankcase
- Twin ball bearing-supported crankshaft
- Schnuerle porting (AKA Schnuerle scavenging)
- Advanced Bi-Metallic Liner. This process uses a double layer of plating material, rather than one thicker layer. This helps the metal to bond to the cylinder, and is more durable. Also, the plating process is more consistent, resulting in a more precise fit between piston and sleeve, for better compression, longer life.
- Side exhaust with muffler with rotatable exhaust outlet
- New carburetor with remote needle mounted on the backplate of the engine (to keep fingers away from the spinning propeller).
- Aluminum backplate.
- Two-Year Limited Warranty
