+1I consider WLToys to actually be hobby grade, albeit entry level hobby grade.
WLToys are absolutely much, much higher in quality than anything you'll find in a Walmart stores.
People would say that well the quality of the components of a major brand is higher, but how often do we end up having to replace certain stock parts, from these big brands, because they crap out. Such as servos and shocks.
Like @WickedFog , I feel there are different levels to hobby grade, nowadays.
