The fischertechnik Advanced Solar construction kit introduces children to the topic of renewable energy in a playful way. A total of 80 components can be used to build three different models: a helicopter, an airboat, and a fan. The central element is the solar-powered rotor system with an integrated motor, which converts sunlight directly into mechanical movement. A matching play figure is included in the set so the completed constructions can be used directly in play. Easy-to-understand assembly instructions support the construction of the various solar-powered models.
