My homage to what will be the greatest flight since the Wright brothers.
Total cost: $6.25
Having your very own Mars helicopter that almost flies: Priceless.
Parts list:
The Guts - I bought a Heli Ball from Five Below and removed the plastic shell $5
I made a 1.25" by 1" box from a sheet of 80lb card stock about $0.50 (could use a Pop Tart box if you wanted) I'll upload the design if anyone wants it.
Wire landing gear - about 20" - maybe $0.75 (if you don't have any around, it's from Walmart)
