def the wrong car for a first nitro but have fun with it, and im sure nitroboy can help. for extras on it, you're goin to need a extra set of belts, a few sets of tires, extra harware, and arms. just anything you think you might break. for stock racing, you'll want to use a .12 3 port, meaning it has 3 flow ports that let air, exaughst and fuel in and out. a good 20% fuel will prolly work for your needs. its pretty healthy for the glow plug too. and by the way, a glowplug is the little thing in the engine head that ignites the fuel causing a cumbustion in the piston sleeve (its a mini spark plug). and for track rules, im assuming they keep with ROAR rules, in which case you're goin to need to look for things that say ROAR legal in terms of engine/exaughst
