Assembly takes about 6+ hours on average, depending on your pace. Every screw, rod, and piston is part of a hands-on learning experience, giving you a deep understanding of how a supercar V12 works.

All necessary tools are included in the kit. No extra tools are required—just follow the step-by-step instructions for a smooth and enjoyable build.

The DM108 is designed for teens and adults (16+). While challenging (★★★★☆), the detailed instructions make it accessible even if you’re new to mechanical assembly. The hands-on process is educational and rewarding.

Absolutely! The motor-driven pistons, rods, and gears move in perfect coordination, and the throttle-linked sound effects recreate the roar of a real supercar engine—making the model both educational and immersive.

The kit contains 800+ precision metal parts, a high-quality wooden display base, tools, step-by-step assembly manual, and a DC 5V USB charging cable for the motor.

The 3.7V 800mAh lithium battery charges via USB in about 6 hours and runs for approximately 20 minutes on a full charge—plenty of time to enjoy movement, sound, and demonstration of the engine.
