田宮 70218 游泳魔鬼魚
這項模型的靈感來自魔鬼魚的泳姿。透過水用摩打和齒輪組的旋轉動力利用曲軸連接魚鰭造成上下運力來向前游動。
Assembly kit. Length: 160mm, width: 148mm, height: 55mm.
Intuitive and easily-accessible assembly process means simple building of the kit, even for beginners.
Submarine motor powers the fin part via a shaft.
The tail fin acts as a rudder, and moving it allows you to alter the direction in which the manta ray travels.
Requires one AAA battery.
The rotary motion of the underwater gearbox is changed to a reciprocating motion with the crank plate, and the left and right fins are moved as if they were flapping.
You can change the direction of travel by changing the angle of the tail.
