Hello everyone, I'm an RC remote control car + military model enthusiast! There has always been a lack of a professional RC crawler car on the market that is both durable and has a military style, so I pulled my fellow model enthusiasts together and designed and developed it ourselves! Our DITV-01 is a 1/10 tactical style PC soft shell, specially adapted for the Trx-4 chassis, and we've also made universal matching parts~ All parts use the original screw hole positions, no need for violent modification, you can restore it to Trx4 at any time, and other chassis with a 324mm wheelbase can also be used! The car shell + adapter parts have been open-sourced on MakerWorld, and I am also making exclusive chassis. We will continue to update compatible parts in the future. Welcome everyone to optimize and modify!

Version 2 adds mounting positions for hooks and a winch based on the original design. Weight reduction has been applied while maintaining structural strength, making it lighter than Version 1.

This bumper series is recommended to be printed with TPU material, which can effectively withstand impact forces and protect the chassis rails.
(Note: The mounting holes are intentionally designed to be a tight fit. DO NOT use materials such as PLA or PETG, as the bumper will not install properly with the mounts and will lack flexibility, making it prone to breaking.)

Meanwhile, the approach angle of this bumper has been specially optimized, providing stronger off-road clearance than the stock bumper.

Hey guys! I’m a huge RC car fanatic, and I absolutely love military-themed models too. But here’s the thing—there’s just no tough, off-road RC crawler out there right now that’s built like a pro-grade crawler (super sturdy and durable) with a cool military style. So I rounded up a few of my fellow RC buddies, formed a little team, and we started designing and building our own RC cars from scratch. Our goal? To make tough, long-lasting military-themed RC crawlers that can handle anything.

Meet the DITV-01—it’s our tactical-style 1/10 scale PC soft body shell. On top of that, I’ve custom-made parts to fit all the different Trx-4 chassis on the market, and I’m also working on designing our very own frame. That’s why we’ve open-sourced all the initial Trx-4 compatible parts, plus the ones we haven’t had time to injection mold yet, over on MakerWorld.

Now, the DITV is just a body shell for now, but with this setup, you’ll have a super reliable military-style RC crawler that’s ready for action. You can hit the trails, go on long crawls with your buddies, tackle mountains and rough terrain, and never get left behind because of a breakdown.

Every part I designed uses the stock screw holes straight from the factory—no crazy modifications, no drilling, nothing. You can even swap your Trx4 right back to its original setup super easily. (I’ve also made parts fit other 324mm wheelbase frames too, but honestly, the Trx-4 is the most reliable pick in my book.)

I’ll be dropping more of my custom compatible parts as open-source designs little by little, and feel free to tweak them or redesign them however you want! Due to some regional issues, I just finally got back into this account after half a year, so I’m back to posting regular updates from now on. If you’ve got any questions or tips, drop a comment below—I’ll reply to every single one within 3 days.
