I purchased my mtx-2 pro spec a year ago. I know the MTX-3 is out buy I can't buy a new nitro kit every year and I love my MTX-2. I was wondering if anyone knows where i can get 5 star upper deck as well as kawahara parts for MTX-2 (they seem to have disappeared).
Ace and Speedtech still has some stuff, both Penguin, Kawahara, and Mugen Upgrades. Keep you eye on Ebay. Here is a link to ACE, and Speedtech. I also believe that Castle hobbies carries a good lot of Kawahara stuff.
