Deliver the fuel efficiency and gas engine ease-of-operation to your .46–.61-size airplane flying experience with the improved Evolution® 10GX engine. Based on the 10cc engine that launched the small-block gas engine revolution, the new 10GX features a new pumped carburettor that makes needle valve adjustment easier and allows fuel flow to be consistent regardless of fuel tank location. For less than $200, the 10GX is a great choice for converting your favourite airplanes to efficient gas power. But what sets the 10GX apart from its nitro-fueled counterparts is its phenomenal fuel efficiency. It takes only 30% of the gas/petrol to run the 10GX the same amount of time it would to run a comparably sized glow engine. That's an amazing efficiency level that results in a cost per flight difference of 90% on average to you.
More flying on less fuel with less fuss – that's what the Evolution 10GX is all about.
Since the first release of the Evolution® 10GX small-block engine, countless modellers have discovered the benefits of gas power in aircraft formerly dominated by the .46-size glow engines. Now that same great engine features a new pump-style carburettor that makes needle valve adjustment easier and allows fuel flow to be consistent regardless of fuel tank location.
The 10GX is a great choice for converting your favourite airplanes to efficient gas power. Standard beam mount dimensions and typical .46-size specification allow it to fit anywhere you might use a .46 to .61-size glow engine. It also means that overall weight is remarkably light, even with its included compact ignition, muffler and recommended 2S Li-Po ignition battery.
But what sets the 10GX apart from its nitro-fueled counterparts is its phenomenal fuel efficiency. It takes only 30% of the gas/petrol to run the 10GX the same amount of time it would to run a comparably sized glow engine. That's an amazing efficiency level that results in a cost per flight difference of 90% on average to you. Since you don't need the huge tank for glow-fuel anymore, finding room for the ignition and ignition battery is easy.
All of the Evolution brand gas engines are designed from the start to provide you with excellent performance at a fraction of your previous operating costs. We have painstakingly designed each engine to insure a hassle free experience without giving away anything in expected performance or durability.

The O.S. GGT-10 uses the latest in model engine technology, it is a petrol engine that uses a glow plug!
This is a revolutionary technology that is set to change model engines forever! It is not merely putting petrol in a methanol type of engine, It is a fundamental re-design from the ground up. The GGT series has taken years to develop and it has been through extensive testing before going into production.
Firstly, the layout and timing of the ports and transfers are completely different to a methanol engine. The shape of the combustion chamber is also very different, as is the compression ratio. This is to suit the fundamental differences between the fuels and the fuel-air ratios that are burnt. Methanol has a wide tolerance to these ratios but petrol does not. Everything is far more critical and well suited to the OS high-precision and accuracy production techniques.A special G5 glow plug has also been developed to match all of the above, it is not just a re-badging exercise! There is way more to glow plug design than you would think. Gone is the unsightly spark plug and cap plus the expensive ignition unit with another battery that you have to charge.The timing of the crankshaft inlet port and its size are also different, which is to help maintain a high gas flow and throttle response.
The ratio of fuel to oil is more critical than a methanol engine. Petrol needs less oil to burn correctly, so the design of the lubrication process also has to change. The GGT series uses a roller big end bearing and plain little end. This needs a little more oil than a twin roller bearing setup, so it is recommended to stay at around 33:1 even after running in. The oil ratio and temperatures dictate the need for a ringed piston setup, which the GGT series has. The clearances inside the engine and the oil feeds are designed to suit the oil available. It puts enough in the right places and copes with the higher temperatures of burning petrol
Lastly, the carburation process has to be very precise with such low fuel-air ratios. To do this, OS has adopted a pumped fueling system and a specially designed carburettor. This provides optimum fueling at all RPMs and attitudes.
Petrol is more volatile than glow fuel which is why the regular tank pressurising via the exhaust is not appropriate. It also means that a starter is preferred to flicking, as the chance of premature firing is higher.
Lastly, have a think about the cost of a gallon of 10% methanol/nitro fuel and compare it to a gallon of regular petrol plus oil. You are looking at a reduction of up to 60%. Add the fact that the GGT-10 sips its fuel at less than 50% compared a methanol engine and the savings fast outweigh the increased cost, let alone the flight time per tank!
Try the New GGT-10, it's a revolution, not an evolution. The GGT-10 has been designed to be used in place of a .40-.55 engines and fits in the same mounting space as a 46AX and 55AX.
OS Engines Silencer E-4010a
Uses a glow plug instead of a spark plug for ignition
Simple starts using a glow driver – no ignition module required
Uses a typical 50:1 fuel:oil mixture
Features a 61H carburetor with PD-08 pump system
Equipped with special shell-type roller bearings
A great power plant for 2-stroke .60 class and 4-stroke .91 class models
The convenience of glow in a gasoline engine.
Glow plug ignition makes the GGT15 a unique 15cc gasoline engine — its performance is the icing on the cake! One of the most important benefits of using a glow driver is that it reduces the engine's overall weight by eliminating the ignition module. Additional features found on this exceptional engine include specialized shell-type roller bearings and a 61H carburetor with PD-08 pump system. It’s the ideal power plant for larger, .61-.91 class models.
