Hmm... I also wouldn't say $187 was particularly expensive for an RTR. That means we're probably looking at ~$100 for a bare chassis?
I was sure that was a 130 class motor, but looking more closely at some of the images that have become available, I'm ready to agree that it's not.
My RC experience is limited to Mini-Z's, so I don't know how powerful those smaller motors are, but if these aren't in the same ballpark speedwise as a Z, it will be a disappointment to me, being something of a speed freak.
If the electronics will take it, perhaps someone can make a conversion motor mount to take a 130?
Still worth keeping an eye out for...
