lipos fit my genetic fine. i was using 4000mah turnigy's with the carbon brace.
i see a couple of used genetics on the bay, but they aren't cheap.
there were a few things about the car i didn't like, pillow ball's for one.
stock diffs were junk but the options diffs were cheap and worked great.
i ran it on a carpet oval with yeah racing foam tires, it was glued.
my buddy made a run at me with an ofna jle12 (or something like that) but he spent a ton of time on it and it was almost as good as the genetic.
i really want to try that atomic, but the mini racing has dried up around here.
