3D model description

I designed a car concept that modifies a tractor into a crawler. I referenced photos and sketches of vintage tractors and speedsters modified from tractors, and designed it under the assumption that the rear axle was extended for crawling functionality.

I used a mission for LCG (Low Center of Gravity) to achieve a lower center of gravity, and installed cantilever shocks on both the front and rear wheels to give it a unique appearance.

As a fun element, I attached a hammer to the shock rocker so that irregular hammering occurs every time the shock moves. Of course, for more serious RC enthusiasts, this feature is optional.

With a slightly higher ground clearance, low center of gravity, and front-heavy weight distribution, the vehicle can handle both crawling and rough terrain driving smoothly. Additionally, the battery can be easily swapped by loosening a single hand-tightened bolt.

Our motto is to use as few parts as possible, make it easy to produce, ensure solid durability, and create a unique design.
