Magnum XLS .61A-RNV

Two-Stroke R/C Aircraft Engine

This is a Magnum XLS .61A-RNV Two-Stroke R/C Aircraft Engine. The XLS .61A-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.

Magnum has been bringing you high performance engines at an affordable price for more than 20 years! During that time the line has grown and expanded to offer a full line of 4-stroke and 2-stroke engines. And, all are made from the finest materials on the latest machinery. Plus, you get the added security of a full one-year warranty that protects you from any manufacturing defects and or premature wear (crash damage not covered). For reliability, high quality, and performance the choice is MAGNUM!

*Requires glow plug, fuel, propeller and support equipment. We recommend using 10% ~ 20% Nitro Methane Fuel with 18% ~ 20% Castor Oil/Synthetic Oil Blend Lubricant. We recommend using a hot heat-range glow plug designed for performance 2-stroke engines, such as Thunderbolt #3. Propeller size will vary based on many factors. We recommend an 11 x 7 propeller for break-in and a 12 x 6 for general sport plane use.
