DeAGOSTINI Building the Mazda Cosmo Sport Rotary Engine 1/2 Assembled Complete Product ● This is a 1/2 scale metal rotary engine. ■ Rotary Engine Scale: 1/2 Size: Approximately 160mm (height) x 180mm (width) x 65mm (thickness) ● By turning the crank handle on the back, the shaft rotates, perfectly recreating the movement within the rotor housing. The LED spark plugs light up in conjunction with the rotor's rotation. It has a realistic, weighty feel. When you turn the crank handle, the rotor rotates (with a slight rumbling sound), and the LEDs light up (see photo 7). There are no noticeable scratches, but please purchase only if you are satisfied with the condition shown in the photos. No claims and no returns accepted. For rotary engine fans, how about displaying it? ● Includes two AAA batteries for the ignition LEDs.
