Overview
Since the release of the Evolution® 10GX small-block engine, countless modelers have discovered the benefits of gas power in aircraft formerly dominated by the .40-size glow engines. But what about the pilots who enjoy even larger airplanes in the .91- to 1.20-size range?
Bring the fuel efficiency and easy operation of a gas engine to your sport flying experience with the Evolution 20GX engine. Its new pumped carburetor makes fuel flow uniform and consistent regardless of fuel tank location and makes needle valve adjustment easier. It’s been designed with a standard beam mount and dimensions that allow it to fit anywhere you might use a .91- to 1.20-size glow engine. The 20GX will breathe new life into models designed for glow power. It’s also remarkably lightweight, even with the ignition system and battery. But what sets the 20GX apart from its nitro-fueled counterparts is its phenomenal fuel efficiency. It takes only 30% of the gas/petrol to run the 20GX the same amount of time it would to run a comparably sized glow engine

TRUST
I first had this engine with a hard run problem so I sent it in for repair. I got a whole new engine back and it is a great runner, and this is in a plane that is my go to plane now. I really enjoy this engine and it has never disappointed me. Trust in this hobby is a big thing and I really appreciated Horizon Hobby stepping up and fixing my problem with this engine. My next engine I buy will be an evolution gas. I have an OS 30cc engine and it has died on me causing me some pain but this evolution engine has been solid. I will say that the plane I have this in works good with this muffler but I do think that the muffler could easily be a problem in some of the different plane designs. The sky The sky there for I fly.
Great Engine!
I have 3 of these engines, and they all run beautifully. Easy to start, very reliable. The only drawback to these motors, is, the muffler supplied with it does NOT fit into any model it is recommended for from Horizon Hobby. All 3 motors I have I had to get Bisson mufflers to fit the applications. Which isn't terrible, just extra cost. Enjoy!
Evolution 20gx2
I have not flown this engine yet, only bench run for the first tank. The pumped carb is great but know needle adjustments are small. Once primed it fired right off and actually ran good out of the box. The LSN was set pretty rich so had to back that off some to good idle and transition. To help save weight I did change out the ignition and installed a glow plug for a brand "X" gas engine and it runs so smoothly either with/without ignition. Like others that have reviewed this engine I too wish the muffler was usable. I am very pleased with the engine so far and would buy another. (I also have the 15GX2)
