What Does ARR Mean?

 When purchasing a Nitro vehicle, many times you will see companies and manufacturers say that a vehicle is "ARR". The term ARR means Almost Ready to Run. If a vehicle is almost ready to run, it could mean one of several things. For some vehicles, such as the Traxxas Revo, you need to buy a battery pack, fuel bottle, and several other things other than gas and batteries to allow it to be ran. Another reason that a vehicle could be labed "ARR" could be because it was missing electronics, such as a Radio and receiver, servo's, etc.
