Note that no electrics are included with this kit. You will have to supply your own radio, batteries, speed control, motor, pinion gear, and battery charger. Whew! The good news is, you won't need much else. Permanently sealed bearings are standard with the kit!
One important note is to read the instruction manual before you begin. And this one is very big! 56 pages to be exact. I was surprised to learn that the RC10B2 almost exclusively uses allen screws. Don't sweat it, Associated does provide the wrenches you will need to complete the kit.
