The Magnum XLS .61A is a single-cylinder two-cycle engine incorporating ABC (Aluminum piston, Chrome plated Brass sleeve) technology for long life, high power output and easy break-in. A dual needle valve carburetor with a remote high speed needle valve for precise fuel/airflow metering is standard. The XLS .61A also features a dual ball bearing-supported crankshaft, a dual bushing-supported connecting rod and a high-flow, noise-reducing muffler.

The Magnum XLS series engine was designed by expert engineers and built by master craftsmen using only the highest-quality materials and CNC machinery. These qualities provide the long life and dependability you have come to expect from Magnum engines.

Uses a high-performance RC long glow plug and 15%-30% nitro fuel with a castor/synthetic blend.
