Nitro Engines
Whether for aircraft, helicopter, boat or car, nitro engines are available to suite every application and use. We are stockists of leading brand engines by SC, OS, Evolution, Irvine, and Force.
Reliability is paramount and as production techniques and designs improve, the modern engines of today represent both quality and effieciency at very affordable prices.
Depending on the size of engine you require, prices start at below £30 for a .99cc.
2 Stroke Nitro Engines
A typical nitro engine found in a RC aircraft operates on the 2 cycle (2 stroke ) engine operating principle. Unlike most normal 2 stroke engines , nitro engines do not have a conventional spark plug. Instead, a glow plug does the work of igniting the air/fuel mixture in the combustion chamber. In this respect, nitro engines are similar to a diesel engine. In both a nitro and diesel engine, a glow plug is energised during starting which causes the element to heat up and glow (hence the name "glow" plugs). This hot, glowing plug ignites the air/fuel mixture. Once the engine is started, the power source to the glow plug is turned off and the element continues to glow from the heat of combustion. So, the glow plug is energised only during initial start up, and after the nitro engine starts to run, the combustion process is self-sustaining and the engine will usually continue to run until the nitro fuel runs out in the tank.
4 Stroke Nitro Engines
Many modellers insist on using 4-stroke engines because they have a wide power range in that they provide more torque at a lower rpm and sound much quieter than their 2 stroke counterparts. They are, however, somewhat more expensive and more complicated than 2-strokes and require a bit more maintenance to operate properly.
Instead of intake and exhaust ports, a 4-stroke engine has intake and exhaust valves. The crankshaft drives a cam assembly and lifter rods, and tappets and valve springs open and close the valves at the right times. Four-strokes produce a fair amount of power, but they’re at their peak at a lower rpm range than 2-stroke engines of the same size. In comparison, the power of a typical .90 4-stroke is roughly equivalent to that of a .60 2-stroke engine. Prices start at around £85.00 for a .30 size four stroke.
Engine spares are available to order. (Please quote the relevant part number when ordering )

The highly acclaimed SC range encompasses aircraft, marine and helicopter engines in a vast range of sizes from 2cc up to 64cc multi-cylinder radial engines.
Ballraced crankshafts and ABC piston/liners
All SC engines have crankshafts supported by dual ball bearings which run and run when compared with the cheaper plain bush bearings found in so many sports engines today.
The all-important piston and liner is ABC in nearly all SC 2-strokes to give the best fit and performance for model engines. ABC setups provide competition levels of power and a brilliant resistance to seizure if the mixture control is wrong. The perfect answer for sport flying.
First to introduce a mass-produced 4-stroke engine, an innovator in every phase of R/C engine production, O.S. also retains a tradition of craftsmanship that pays off in durability and power. Each new engine is the product of over two years of testing and design—and more than two generations of R/C engine experience.
Evolution Engines are designed to support every demand from RC modellers with engines that perform better than the most recognised brands and do it for less cost. The use of true hard chrome plated sleeves in the Evolution glow engines is a rule of the design--no compromise for other easier but less durable plating processes. A three year warranty on every Evolution Engines brand engine guarantees that it will be there when others are not.
