• Motorise your K'NEX models to make them more realistic with these two battery powered motors.
• Turn concept models into "technology at work"
• Requires 2 AA batteries per motor (not included)
• Pack includes two motors

Key Concepts

• Build investigate, and experiment with motorized models that have constant speeds and continuous operation
• Build 2 models of the same device with different gearing systems and operate them side by side to observe the effects of the gearing variations, increased speed and increased force.
