Design a high-detail 3D model of a luxury sports RC car inspired by Ferrari/Bugatti. Split the model into two printable parts: a sleek, aerodynamic top body (with curves, vents, lights) and a functional bottom chassis (with wheel arches, motor space, battery compartment). Scale should fit 1:10 or 1:12 RC cars. Add realistic car details like rear diffuser, side skirts, front splitter. Ensure smooth geometry, no thin walls, printable STL. Include mounting guides to attach top and bottom. Keep wheel wells open for RC tires.
