This is a Magnum XLS .52A-RNV Two-Stroke R/C Aircraft Engine. The XLS .52A-RNV 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 for precise fuel/airflow metering with an optional rear needle valve assembly is standard.
Your 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 an engine of this caliber. Magnum XLS Series are true ABC engines with true hard chrome plated (not nickel) brass cylinder sleeves for longest service life. Front rotor Schneurle porting optimizes power and efficiency of the two-stroke design, and aerospace quality steel ball bearings reduce friction to maximize RPM and power.
