Rubberband Powered Lego Car

An idea i had one snow day when i was bored

Ok how to work it
Hook rubberband* to the yellow piece that is on the end of the driveshaft not the axel
Next hook it to the blue piece near the front pull back to wind and let go when ready


* no rubberband shown because i wound it up to far and broke it

**note a wide spacer on the left rear axel broke in half and fell off this was a mistake it should match the other side

*** found rubberband should look like last pic when attached correctly
