This is a self-build brick model of a retro-futuristic steampunk airship. It has a two-tiered design packed full of details, and five moulded mini-figures are included to add to the fun. There is a control knob on the lower right side of the airship which, when turned, will activate multiple clever interactive features all at once; these include swinging tail-fins, rotating side gears, spinning engine propellers, and a rotating rear propeller. It is sure to look great on display in your home or office..
