Hey.
Great to hear your starting in Nitro. I have a HPI Nitro MT and they are great fun and fast aswell (For a beginner) - I'm having a lot of fun learning about it, and HPI parts seem to be pretty readily available.
Check out the Nitro MT - It's around $600AUD so Im guessing it will cost around $300US.
It's zippy for a first car
Have fun!
Josh.
