These are the things you will need..
Redcat starter kit ( includes plug ignitor w/ charger, fuel bottle, and a couple general purpose tools)
After Run Oil
Air Filter Oil
20% Nitro fuel
6v Hump Pack w/ charger or 4 AA Batteries for car
8 AA Batteries for the remote
Blue Loctite
A Couple Glow Plugs
Fail Safe ( not required but highly recommended to prevent a "run away" situation )
When you first get your buggy you need to check all screws to make sure they are tight, and apply the loctite to all metal to metal screws. As for the glow plugs, I prefer the OS #8. I bought 8 reachargable AA Ni-Mh batteries w/ charger for my remote and a hump pack w/ charger for the car to avoid hassle and expense of alkaline batteries. Good Luck and welcome to the addiction
