Complete Multi-Pack Value: Includes 2 identical full sets, making it perfect for building twin-motor projects (like an RC boat or 4WD vehicle concept) or sharing with a classmate/sibling.

Perfect Fitment (No Guesswork): The 8cm 3-blade propellers are precisely molded to snugly fit the 2mm motor shafts of the included 130 DC motors—no glue or adapters required.

Easy, Solderless Prototyping: The battery cells come with flexible, color-coded positive (red) and negative (black) wire leads that can be easily twisted onto the motor terminals for instant power.

Safe & Beginner-Friendly: Runs safely on standard low-voltage AA batteries (1.5V to 3V DC), making it perfectly safe for school children and young inventors.

Encourages Practical STEM Learning: Ideal for teaching kids the basics of electric circuits, kinetic energy, polarity, and motor mechanics.
