This is the Evolution 10GX 10cc Gas Engine with Pumped Carburetor. 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 10GX features a pumped carburetor 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 favorite 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 you don't need the huge tank for glow-fuel anymore, finding room for the ignition and ignition battery is easy.

Since the first release of the Evolution 10GX small-block engine, countless modelers have discovered the benefits of gas power in aircraft formerly dominated by the .46-size glow engines. Now that same great engine features a pump-style carburetor that makes needle valve adjustment easier and allows fuel flow to be consistent.

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 LiPo ignition battery.

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.

I haven't had a chance to run engine yet, but casting and construction is outstanding. Almost everything you need is in the box, except fuel tank and ignition power source. Amain shipped quickly. Parts are available in USA at Horizon hobby. Will give further info on performance soon.
