UGears Tyrannosaurus Tex Model Kit 

Description:

• Brand: Ugears
• Color: As picture shown
• Level: Advanced
• Number of components: 249
• Estimated time for assembly: 8 hours
• The top of the tail conceals the winding key
• Remove the key and insert into the ratchet mechanism on the dinosaur's left side, making sure the head of the left femur is clear of the opening (if you need to, flip the on/off switch to the "on" position, then spin the gear above the T-Rex's shoulders to move the leg)
• Flip the on/off switch to the "off" position (toward the head) and wind the mechanism half a dozen times clockwise, replacing the key to its position between the tail and body
• Place the Tyrannosaurus on a smooth, flat surface, holding the automaton by the body (don't squeeze the legs together!), flip the on switch and release
• Your Tyrannosaur will stalk away, in search of its next meal, its tail swinging and jaws crunching up and down in anticipation
• This mechanical DIY wooden model of a walking tyrannosaur is driven by a metal spring, which transmits power through a reduced gear, turning the axle that drives the legs
• A clever system of links and connections allows this king of the dinosaurs to walk on its own two feet—the first bi-pedal walker in the Ugears collection
• An eccentric gear sets the tail swaying in synchronous motion with the legs, helping the dinosaur keep its balance and not fall to the side, just as in nature
