Baja Bug Style 1/10 M-Chassis RWD RC Car (RS04R Chassis)

🏎️ Overview A fully 3D-printable 1/10 scale M-chassis RWD RC car featuring an iconic Baja Bug body style. Built on the custom-engineered RS04R chassis (225mm wheelbase), this model combines aggressive off-road aesthetics with modular, hobby-grade engineering. It features a clever modular body system: using a shared central body tub, you can easily swap the front nose and fenders to switch between a race-inspired Wide Body Type and a classic off-road Bugeye Type! ⚠️ IMPORTANT NOTICE Please download and read RS04R_MANUAL.pdf and BOM.pdf first! They contains step-by-step assembly instructions with 3D CAD illustrations, as well as the detailed parts list. 🛠️ Key Features - Modular Body Conversion (2 Styles in 1):- Wide Body Type: Aggressive, widened stance for modern desert/rally vibes. - Bugeye Type: Classic vintage Baja Bug look with exposed headlights. - Both styles share the same main body shell—simply swap the front nose and fenders to transform your ride!
