New to the popular Robocraft Series is the Mechanical Fish. The movement of the crank arm is translated into the tail's left and right movement allowing it to swim. As opposed to the previously released blowfish (Item 71114), which had its body above the water, the upper half of this item acts as a float and allows the dorsal fin to be exposed to the surface with the rest of the fish totally submerged as it swims.

Relaxed Swimming Action
This fish robot swings its tail from side to side while swimming along. The main body stays underwater while the dorsal fin protrudes when it swims. The Submarine Motor Mini and Underwater Gearbox move the tail via a crank and linkage rod mechanism. The main body, fins, and foam float are all conveniently included in this easy to assemble set. Tamiya and mechanical fish logos as well as two kinds of eye stickers are included.

Enjoy the Action!
The fish robot can swim not only in straight lines but also in circles by changing the angle of the tail fin. To change the angle, simply lift the tail fin then reposition to the right (clockwise swimming) or left (counter clockwise swimming). Slightly or greatly adjust the tail fin angle for the fish to swim in large or small circles. Furthermore, the swimming posture of the fish can also be adjusted by changing pectoral fin position.

Features
By changing the angle of the tail you enjoy watching your fish swim in circles.
It is possible to change the angle of the lower body fins.
The upper float has a plastic case with styrene foam.
No cement required for assembly.
