Bluetooth controlled LEGO replica of Cadillac CTS-V

Welcome guest blogger DamonMM2000

Hey there! I am DamonMM2000, and I build LEGO MINDSTORMS Ev3 robots. Today, I would like to introduce my 103rd Ev3 MOC (from what I've counted): CTS-eV3! CTS-eV3 is a Lego replica of the 2010 Cadillac CTS-V Coupe. With RWD (Rear Wheel Drive), lots of speed, and more than adequate torque, this motorized creation is like the real car. Having been over half a year in the making, there has been many trial-and-errors (including chassis, drivetrain, and exterior redesigns). But I am quite satisfied with the final outcome! CTS-eV3 has a 4.5:1 gear ratio (if you count the differential, the gear ratio is 3.2:1), accomplished by driving a 36 tooth gear meshed with an 8 tooth gear in a unique setup. Actual speed is a few tenths under 4 Kph! This two door coupe has been relatively replicated, including the visible V8 piston engine along with the Corvette inspired supercharger. Special thanks to Builderdude35 for his help; he came out with his Bluetooth tutorials for me, so I really appreciate that!
