TX19 - Electric STEM Kit - Propeller Biplane

Propeller Biplane (TX-19) ⭐⭐⭐ · ~30 min

⚡ Principle The biplane glides forward using the reaction force of the air. The motor rotates the propeller at high speed, blowing air backward. This creates an aerodynamic thrust that pulls the plane forward along the ground.

🔩 Parts

• Wooden boards (frame and wings)

• High-speed motor ×1

• Propeller ×1 + shaft sleeve ×1

• Plastic wheels ×4 + iron shafts ×2

• Battery holder with switch ×1

📋 Steps

1. Fix board 6 between the two boards 11, then secure them through boards 1 and 4. Fix the two boards 10 onto board 1.

2. Fix board 3 through board 7 to board 1, then fix the two boards 8 onto board 4.

3. Run the motor through the two boards 5 and secure them firmly to board 1.

4. Connect the red and black wires to the motor terminals (do not reverse), then secure the battery holder to board 1.

5. Fix board 2 (the top wing) onto the board 8 supports.

6. Put on the axles and wheels, then install the propeller and batteries. Press the switch and watch the plane taxi!

⚡ Fun Fact! The first successful flight of a biplane was by the Wright brothers in 1903. It only lasted 12 seconds and covered 36 meters—less than the wingspan of a modern Boeing 747!

💚 Tip If the plane doesn't move straight, check that the wheels spin freely on the iron shafts and that the wings are perfectly aligned.
