The Laser four-strokes first appeared on the market in 1983. They were the brain-child and first engine design of engineer, Niel Tidy (UK). The engine came about through Neil's involvement in radio control aircraft. Following a successful proposal by him to the Department of Trade and Industry, a "Support for Initiative" grant to begin producing the engine was awarded to ACG Ltd, a precision component manufacturer owned by Mr Reg Gross. By 1984, demand had grown to the point where AGC Sales Ltd was formed to market the engines [1]. The engine on the left above is one of the earliest engines featuring a sand blast finish on the nose section. The engine on the right is from a later production; both are of 0.61 cuin displacement. The Laser was one of the very earliest to feature full CNC, bar-stock manufacture. The range has included single cylinder engines of displacement between .45 and .180 cuin although the .45 and .61 were discontinued several years ago in favour of the larger engines. There has also been V-twins of .12, .160, and .300 cuin displacement, plus a .61 diesel four-stroke. They are universally regarded as light, powerful, precision jewels that have powered many national and international contest winning models. Production is no more than a few thousand per year and there is always a waiting list. For more information, visit http://www.laserengines.com/.
