Nice score man.
I've got 2 MiniZ cars (MR01) and an OL m'self.
Z's are definitely a fun class, not to mention this is the scale where you start seeing SERIOUS people at the tracks/races.
If you want to get LOADS of Mini-Z info, make sure you visit TinyRC's big brother site
Mini-ZRacer
Oh, and since you seem to be picking up all kinds of different RCs...Make sure you checkout the 1/43rd scale "Epochs" too.
