Description
Bring heavy-duty construction power to your RC collection. This detailed 1:14 scale AF D4 RC bulldozer is inspired by the iconic CAT D4 and designed specifically for 3D printing. With full remote-control functionality — tracked drive and a moving blade — it is both a challenging and a rewarding build.
Most parts print support-free. The model is organized into clear assembly sections, and the download includes a calibration STL for a perfect fit — drop an MR128ZZ bearing into the test part; it should fit with slight resistance. Note: the tracks have adjustable tension — check the manual.
A full step-by-step build manual is available on our Build Manuals page.
