• Swim Loosely by Moving the Tail Fin
• This is a fish-shaped robot craft set that swims by moving the tail fin from side to side.
• The point is that the back billet rises above the water and all the mechanical parts sink below the surface.
• A mini underwater motor is combined with an underwater gearbox, and a crank and a link rod are used to move the tail fin by changing the rotation motion to reciprocating motion.
• Comes with all necessary parts such as the body, fins, and Styrofoam for floats.
• Assembly can be completed easily without using adhesives by fixing screws and fitting.
• It comes with stickers such as two kinds of eyes, Tamiya mark, and Mecha fish letters.
• Let them swim. You can make them swim straight or in circles.
• Pull up the stopper of the tail fin to change the mounting angle, and move the tail fin to the right in the direction of travel to turn right, or to the left to turn left.
• Also, if the angle is small, it swims in a big circle, and if the angle is large, it swims in a small circle.
• You can also adjust the angle of the pectoral billet and change the swimming posture, such as moving forward or backward.
