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.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 the pectoral fin position.
