2. Product Overview

The Poraxy STEM Model Car Kits include components to build five distinct models:

• Wind-Power Car (Gliding Aircraft): A propeller-driven model that demonstrates principles of thrust and aerodynamics.
• Solar Car: A vehicle powered by solar energy, with an option for battery power.
• Balance Car: A unique two-wheeled model designed to maintain balance through its center of gravity.
• Gear Car: A car that utilizes a gear mechanism for movement, demonstrating mechanical advantage.
• Wireless Remote Control Car: A car that can be controlled remotely, illustrating basic electrical circuits and radio signals.

3. Components List

Each kit contains precisely laser-pre-cut wooden pieces, motors, wires, battery holders, gears, wheels, and other necessary small parts for assembly. Detailed component lists for each specific model are provided within their respective instruction cards included in the kit.

4. Assembly Instructions

Follow the step-by-step instructions provided on the individual instruction cards for each model. Ensure all pieces are carefully detached from the wooden sheets. The edges are smooth for safe handling.

4.1. Wind-Power Car (Gliding Aircraft) Assembly

Assemble the wooden body of the aircraft. Connect the motor and propeller according to the wiring diagram. The motor drives the propeller, which generates thrust to move the aircraft forward.

4.2. Solar Car Assembly

Construct the car chassis and attach the solar panels. This model supports two operating modes: solar power (no batteries required under direct sunlight) and battery power (for indoor use or low light conditions). Ensure correct polarity when connecting wires.

4.3. Balance Car Assembly

Assemble the unique T-frame and large wheels. The design of this car relies on a low center of gravity to maintain balance, similar to a tumbler toy. Ensure the heavier bottom part is correctly positioned.

4.4. Gear Car Assembly

Construct the car body and attach the various gears. This model demonstrates how gears transmit motion and can achieve a
