this thread might show there is no one, settled, definition. especially if a roller does not have to be equipped to roll. no?
Yes, it shows there are different opinions, but I'll still hold to the common thought
If it can't roll....it's not a roller. It's a "pre-roller".
To me
RTR (ready to run) means out of the box it should be ready to run (batteries are a debate on this issue, I think RTR should mean batteries but that's debatable)
ARTR (almost ready to run) means motor, ESC (if electric) and servos, no radio or batteries.
Roller means basic vehicle with no motor or electronics
Pre-Roller means basic vehicle with no tires and maybe no body.
Now most of the items have something subjective about them, which is why you need to specify every detail prior to a purchase, but a Roller HAS to have tires otherwise....it can't roll.....
