Yep, the RG is the best engine to get in your first 1/8th scale buggy, It has pllenty of power, is easy to tune, and reliable. That gives you more time to learn how to drive, and not spend so much time messing with it trying to get it to run right. Most expensive race engines are finicky to tune (Not just the carb settings, but also the clutch and pipe as well) and require you have more knowledge about engine tuning and engine setup.
