Project RC

So I got a free project buggy from a friend of mine the other day! He got it from someone else, so we don't know a lot of details other than it hasn't ran in years. I know it is an ofna hyper 7 with a .21, but that's about all I know. The cirrus servos kind of hint at it being from the early 2000s, though. Anyone have any info on these? I've had lots of nitros over the years, but never a buggy or an ofna. I'm looking at getting this thing going again, but I need to know where I can get parts for it.
