🏎️ RTR
Ready-To-Run — a model that comes fully built with electronics installed; usually just add a battery and charger.
What it actually does
RTR stands for Ready-To-Run: a model that arrives assembled with the motor, ESC, servo and radio already fitted, so you can be driving the same day. It is how most people enter the hobby, and there is nothing second-rate about it — plenty of very capable machines are sold this way.
In practice
The usual thing to check is what is *not* in the box. Many RTRs still need a battery and charger, and the included pack is often modest. Kits, by contrast, arrive as parts for you to build and choose your own electronics for — more work, more control, usually better components for the money.
Worth knowing
Before the first run, check the wheel nuts and the gear mesh, and set the ESC to the right battery chemistry. Factory assembly is quick assembly, and these three things are the ones most often left needing attention.
Common questions
Is RTR worse than a kit?
No — just different. An RTR gets you driving immediately and teaches you what you actually want; a kit teaches you how the car goes together and lets you pick every component.
What do I still need to buy with an RTR?
Usually a battery and charger, and often AA cells for the transmitter. Check the box: "RTR" does not consistently mean everything is included.
