In a sense, Traxxas is killing RC somewhat. At the LHS I work it, the Traxxas parts section is ever-expanding. When new parts come in, they get sent to a box down below because they have no place on the parts panels.
Every 6 months or so we re-do the parts panels for any given brand. With Traxxas, it is difficult to find enough space for everything since they don't discontinue many parts (the store often stops carrying them long before Traxxas stops making them).

This also makes any particular Traxxas part more difficult to find and/or keep in stock. I suppose this isn't so much of an issue for online hobby shops, but for the brick-and-mortar type it is.

Another thought concerning Traxxas and hobby shops - if Traxxas redesigned a whole new truck, they'd have a whole new line of parts. There's no way a hobby shop is wanting or even willing to carry a whole new line of parts when a company releases so many vehicles within such a short period of time. So from this perspective, it's actually better that Traxxas is just changing around platforms to come up with something new.
