Here’s a look inside a $75 nitro engine. This engine is alpha based. It runs great and is very easy to break in and tune. Out of the box the engine comes with pretty low pinch but it holds that pinch for a good 6 gallons before you start noticing a performance loss. In this video I give a brief tutorial on how I repinch sleeves. Hope you enjoy and my next video will be the break in of this engine and another trackstar that I modified significantly. Hope you enjoy these videos
