some stuff you will need to run a nitro...

starter kit.....this will come with a fuel bottle, some wrenches, screwdrivers, glow plug ignitor and charger
inline fuel filter....good idea to run...the rxt-1 and rxb-1 come stock with inline fuel filter
air filter oil...tacky oil that collects dust etc. so it doesnt enter your engine
after run oil.....after running your engine this helps keep it from "gumming up".. keeps everything lubed
temp gun....great for tuning and making sure your not running to hot or cold ( both are bad on a nitro engine)
failsafe... as mentioned in previous post on this thread...helps keep your car from "running off" on you
throttle return spring... (optional but nice) another device to help keep your car from "running off" on you


I'm sure I forgot something so feel free to add....lol
