Power output is one of the key factors of the success of LASER ENGINES. Design features such as the straight gas flow from the carburetor improve performance and follow full size practice. They are designed to give high torque enabling large efficient propellers to be used reliably. This also reduces noise and increases the life of the engine. The NITROMETHANE is not needed for normal running but will significantly increase performance. Nitromethane is very expensive and the major cause of corrosion. Power figures can be highly misleading as they depend on many factors including nitromethane content in the fuel and the speed the engine achieves maximum power. Laser engines let competition results show performance and do not publish power figures. LASER ENGINES are designed for the serious modeler who demands power with reliability and an engine with exceptional life.

LASER-70 Exceptionally compact and light, similar height to other 48 - 52 4-stroke engines. Best power range 9-10,500rpm static. Ideal for sports aerobatic models and multi engine models. where power to size ratio and reliability are important.

LASER-80 similar height to other 65-70 4-strokes. Wide useful power range from 8-10,500rpm. A direct replacement for the very popular Laser 75 fitting the same mounting but giving greater power.

LASER-100 Long stroke engine giving huge torque at low speeds for large propellers. Useful power range 7,500-9,000rpm. Ideal for the larger scale model and exceptionally quiet at low propeller speeds.

LASER-120 Very compact engine shorter than any production 90 4-stroke engine. Not as powerful as other 120 4-stroke engines but will fit into small cowls. Useful power range 8-9,500rpm. Always use the LASER-150 if a 120 is called for.

LASER-150 Lighter and shorter than any 120 4-stroke but with more torque. Useful power range 8-9,500rpm. Our best selling engine, powerful, reliable, ideal for sport and scale models with proven international competition success.

LASER-180 The Laser-180 single is a long stroke engine providing high torque at low speed. It will pull up to a Classic Master 20 x 6 propeller at over 7,000rpm. The engine is ideal for the larger scale model. It is ideal for models such as the Flair Stearman and Tiger Moth and WW2 type aircraft where a Classic Master 18 x 8 propeller can be used.No attempt has been made to lighten the engine as these models will need the weight of the engine in the nose. It is not suitable for the lightweight aerobatic models such as the Giles, Extra Cap where the additional weight compared to the Laser-150 would be a disadvantage. The Laser-180 has proved to be an exceptionally reliable and easy to operate engine with tremendous pulling power due to the larger propellers. The low speed gives a very realistic sound and the vibration levels are low.

LASER Vee Twins. The Vee twins are exceptionally smooth running very powerful and reliable. The Vee layout gives perfect primary balance and the offbeat firing gives the engine a distinctive and realistic sound. The smooth power of the Vee twin puts less vibration and stress into your model and radio gear resulting in longer life and lighter airframe structures.

LASER-160v A compact engine with a wide power band between 8-9,500rpm.

LASER-200v The most successful competition 4-stroke twin ever produced. Will fit easily into scale radial cowls and in Continental and Lycoming cowls. The engine gives best power between 8-9,000rpm.

LASER-240v Smaller but similar weight to the 200v the engine is designed for FAI aerobatics. The engine has the highest power/weight ratio of all Laser engines. Due to the small size it is essential that good cooling is arranged in the model, it is not as tolerant as the 200v.

LASER-300v Designed for the larger model, the 300v is the most powerful in the Laser range. Performance between 7,500 and 9,000rpm. it has excellent running qualities and will suit the new 12Kgs FAI rules.
