i have it. its a pretty through book. it covers everything from engine make=up, to tuning, to breaking =in an engine, how to keep up your engine, pipes, carbs, settings. lots of good stuff. it was published in 2004, i think, so it has up-to date info. retails for about $30.00. and has everthing you'll ever need to know about rc nitro engines. as long as they dont come out w/ any major ground breaking engine stuff you'll be set: ). hope this info helps you deside on the book. clay unruh
