I made some poor initial decisions and kind of wasted money on this build. I started the Tamiya kit and once well underway realized I needed the Dragon kit for the late drive sprockets and a few other parts. So I could have skipped the Tamiya kit altogether and just used the Dragon kit as a basis. I still would have bought the Fruil tracks, and probably most of the aftermarket brass as well, so I would say the newer kit would not have saved a ton of money.
Not sure about something like the Meng KT though....not sure what it includes and whether any aftermarket stuff would be needed.
