I would be a little more clear than that. It used consumer grade hardware for certain components. Key avionics are still radiation hardened and as far as I know, things like the blades, landing legs, and chassis are all custom. The motors were technically off-the-shelf (maxon DCX), but were modified and customized. The thing cost $80,000,000 to design and build.

I also suggest getting a bike, although you will probably have to scout a bit to find a safe route. If you are spending 100 minutes walking at a fast pace, that means you are probably walking about 5 miles. On a bike that should take only about 20-30 minutes. You might have to go a less direct route to stay off of busy streets, but even then it should be much faster than walking.
