Features

• Swim with flapping motion!
• The manta ray (manta ray) is said to be admired by divers due to its huge body and friendly personality.
• This is a craft set with the image of a large fin flapping and swimming slowly.
• The rotating motion of the underwater gear box is changed to a reciprocating motion by the crank plate, and the fin of the soft resin sheet is moved up and down while flexing.
• The undulating flapping of the fins creates a movement that sends water backward, and the force moves forward.
• All the necessary parts are set, and the simple structure makes it easy to assemble.
• You can change the direction of travel by changing the angle of the tail. • A float with a tail made by bending a resin sheet is fixed to an underwater motor using a suction cup.
• If you attach the tail at an angle, you can go around right or left.
• You can also play in a small space by adjusting the direction of the tail and letting it swim in a small circle.
• In addition, you can change the swimming posture by shifting the float back and forth.
• One AAA battery (sold separately) lasts for about 3 hours.
• The rotating motion of the underwater gearbox is changed to the reciprocating motion by the crankplate, and the left and right fins are moved as if flapping.
• If you change the angle of the tail, you can change the direction of travel.
