Let's start with explaining what I mean when i say Toy grade.
Toy grade - Low Performance & not serviceable => performance usually slower, not suppose to break, but in case it will - you won't be able to fix it, no suspensions.
so according to this definition - this is a toy grade (at least from the spec that appear here).
although as written there it is RTR (ready to run) - which usually related to the hobby grade.
I hope it helps somehow ;)
