Definition: In the world of radio controlled vehicles, RTR usually stands for ready-to-run. It means there is little or no assembly required to operate the RC. An RTR vehicle may only require installing batteries in the controller and charging the battery pack. For hobby-grade RCs there may be a few more steps involved - such as attaching the body - but the vehicle doesn't require major assembly.
The meaning is essentially the same, but RTR can also stand for ready-to-ride and ready-to-race. Similarly, RTF for ready-to-fly would apply to airplanes and helicopters. For vehicles that might require a small amount of assembly or the purchase of additional parts but don't have to be built from the ground up, the terms ARR (almost-ready-to-run) or ARF (almost-ready-to-fly) might be used.
Also Known As: RTF | ARR | ARF | ready-to-run | preassembled
