For the price it is an excellent engine. Idles very smooth. May not have the explosive power as the super expensive engines, But not much slower either. It is great for buggy or 1/8 GT car.Low end torque is very nice. You will enjoy this engine for sure. Spare part price are also very reasonable.

Nice little engine with exceptional value for the price. It was the easiest motor to break in that I have ever owned. Gas mileage is close to 10 minutes. I have not had it that long and have put just about a gallon on it. Speed is comparable to the most expensive engines on an smaller indoor track. I have not had a chance to race on a large outdoor track to see how it compares. I will write another review after a few gallons, but so far so good. I will definitely buy another one as a practice/backup engine.

I really like this engine. I bought it with the intention of testing homemade 0% nitro fuel, and to experiment with modding a nitro engine. So far it has taken everything I have thrown at it and is still going strong. I would definitely recommend this engine to anyone whether they are just learning nitro or they want a fast engine. I bought a similarly priced SH engine off of ebay and the X- Act is way faster. I plan on buying another one once they are in stock and I plan on being much nicer to that one. The only problem I had was that there are no stock needle settings in the instructions. Other than that, 5/5.
