The Tamiya TT-01 and TT-02 are both classics in the RC hobby, and it’s hard not to have some affection for them even if they aren’t the fastest or most advanced chassis out there. The TT-01, for a lot of people, was their first “real” hobby-grade car. It’s simple, durable, and forgiving, which makes it a great entry point. You can bash it around in a parking lot, swap bodies, and not worry too much if it takes a few hits. It doesn’t have all the tuning options of a race-oriented chassis, but that’s part of its charm—it’s approachable, and it works.
The TT-02 came along as a natural evolution, keeping that same spirit of accessibility but modernizing it in some smart ways. It’s a bit stiffer, a bit easier to maintain, and the layout feels more up-to-date compared to the older TT-01. For newcomers, the TT-02 is probably the better choice now, simply because parts are everywhere and Tamiya keeps releasing body kits on it. That said, a lot of long-time hobbyists still have a soft spot for the TT-01, maybe because of nostalgia, maybe because it has a certain rawness the TT-02 smoothed over.
Neither of these cars is really a hardcore competition machine, but that’s not the point. They’re platforms for fun—easy to build, endlessly customizable, and perfect for someone who wants to try out different bodies, wheels, and light upgrades without getting lost in complicated setups. In a way, they represent what Tamiya does best: making RC feel welcoming, approachable, and fun.
