If someone said i could pay them 20 bucks to teach me how to properly start, tune, and run my nitro, i would have done it in a second. Heck, i might even still do it. 20 bucks for expert advice on how to tune an engine can save you a lot in the long-run. You can read everything in the world online, but its never equal to the experience you get when you're actually doing it or being shown how to do it.
