One of the more visually stunning RC trucks to ever come out of the Tamiya factory has to be the TXT-1 monster truck. From afar it looks basically like a Tamiya Clod Buster with an aftermarket chassis, but up close it’s a different story completely. Unlike the Clod, with its dual axle mounted motors, the Tamiya TXT-1 features dual motors that are mounted up in the chassis. Power runs from the transmission, through driveshafts, and out to the axles, just like a full size monster truck. Even better, the TXT-1 features a beautifully machined aluminum chassis, a four link suspension, sway bars and a set of chrome wheels. In reality, the only thing the TXT-1 and Clod Buster have in common are those giant chevron tires. I’ve been wanting to build one of these awesome trucks since I first laid my eyes on one and I have finally gotten that chance. Follow along as I document the build of the Tamiya TXT-1 with over 90 pictures!
A really nice surprise you’ll find in the TXT-1’s box is that it comes with two bodies. You heard right, the TXT-1 comes with two bodies. One is pre-painted just like the box art, while the second is clear so you can style your TXT1 however you’d like. More manufacturers should do this.
Here is another photo of the Tamiya TXT-1’s aluminum frame rail. From the factory the TXT-1 chassis has a brushed look to it but it wouldn’t take much work to polish them to a mirror shine. Tamiya offers an optional blue anodized lightweight version of this chassis too.
The TXT-1 includes chrome wheels with a giant set of tires. While the tires are the same as the ones that come with the Clod Buster, the wheels have a different mounting pattern. You can still mount these wheels on a Clod, or vice versa, as long as you use the right wheel hubs.
This is a TXT-1 wheel hub. If you’re familiar with Clod Busters you might be able to see why Clod wheels won’t work with these hubs, the holes are too big. The good news is, both Clod and TXT hubs use the same brass hex so you can use either truck’s hubs.
…and its sway bars. My only gripe about the entire truck is what you see here. Why oh why did Tamiya disgrace this beautiful truck with those cheap zip ties holding the sway bars in place? There had to be a better way.
One of the things we found really funky about the TXT-1 is that, thanks to its chassis mounted motors, it tends to pull the left front wheel up when you slam on the throttle. I think the shocks and sway bars will need some tweaking to fix this “problem”.
