What Does RTR Mean?

 If you are new to the hobby, you probably wouldn't have heard this term before. When you see something such as "HPI Savage X 4.6 RTR", the RTR stands for Ready To Run. Ready to run means that all you need is your fuel, and possibly some AA batteries for your Transmitter and receiver, and then you are ready to put the fuel in, and go! Note: This does not mean that you should not break your vehicle's engine in by the factory specified instructions in the manual included with most vehicles.
