Upgrading the Tamiya DT-01 and the classic Grasshopper/Hornet platforms involves a similar philosophy: maintain the nostalgic charm of these entry-level buggies while improving their durability, driveability, and efficiency for casual bashing or light off-road use. Both platforms are simple and iconic, and the goal is not to turn them into competitive race buggies, but to enhance their usability and reduce their weak points while keeping their unique personalities intact.
The Tamiya Grasshopper is a popular RC buggy model known for its iconic design and simple yet effective chassis. Introduced in the 1980s, it has become a classic choice for both beginners and experienced RC enthusiasts. The Hornet was considered a step up from the Grasshopper in terms of performance and features designed to be a more competitive model with improved horsepower. The DT-01 chassis features a tub-style design, similar to the Grasshopper chassis.
This training book has been developed from the ground up for beginners who know little about electric power RC technology. As part of our RC Technology Self-Paced Training Series, this book gives an introduction to the Grasshopper/DT01 EP offroad architecture. The primary goal of this book is to explain the various technical concepts in very simple language. We believe that this book and its support materials have everything you need for an informative, interesting, challenging and entertaining RC educational experience.
This book covers both the legacy Grasshopper/Hornet chassis and the newer DT01 chassis.
When I first got my hands on a Tamiya DT-01, I didn’t really know what to expect. Compared to some of Tamiya’s fancier buggies, the DT-01 is about as straightforward as it gets — but that’s exactly why it’s such a great entry-level car. It’s simple, tough, and built to just go out and have fun without overthinking setup or upgrades.
The DT-01 is a rear-wheel drive buggy chassis, and you usually see it with classics like the Mad Bull, Mad Fighter, or Rising Fighter bodies. The design is super basic — big bathtub chassis, rear motor, and a pretty minimal front suspension setup. It doesn’t have the precision of something like a DF-03 or the history of an Avante, but it does have a rugged, no-nonsense feel that makes it perfect for beginners.
Building it was quick and painless. Honestly, it’s one of the easiest Tamiya kits I’ve put together — not a ton of parts, and the instructions walk you right through. It’s the kind of kit you could probably build in a single evening, which is nice if you’re new and don’t want to get lost in a sea of tiny screws and adjustments.
Driving the DT-01 is pure backyard fun. It’s not the most refined buggy out there — the steering can feel a little sloppy, and it definitely doesn’t corner like a race car — but it makes up for it with durability and go-anywhere personality. With the big Mad Bull wheels especially, you can run it on grass, dirt, gravel, or pavement without worrying too much. It just plows along and takes hits without breaking a sweat. As a beginner, that’s exactly what you want: a buggy you can drive hard, crash, and keep running.
What really stands out is how tough this chassis is. The DT-01 has a reputation for being nearly indestructible. I’ve already cartwheeled mine a few times and even clipped a tree, and it just kept going. Replacement parts are cheap and widely available, too, which makes it a worry-free car for learning.
Performance-wise, it’s not going to blow your mind. It’s more of a basher than a racer. But that’s okay — it’s fun, it’s forgiving, and it gives you the freedom to just enjoy RC without pressure. Plus, if you ever want to tinker, there are still a few hop-ups you can add, like oil shocks or a hotter motor, to give it a little more pep.
Overall, the DT-01 is kind of like the “first bike with training wheels” of RC buggies. It’s not flashy, but it teaches you the basics, it’s nearly unbreakable, and it makes you smile when you’re out ripping around the yard. For beginners (or anyone who just wants a stress-free basher), it’s a solid little buggy that earns its spot in the Tamiya lineup.
