If you were to build the exact same helicopter here based on those parts what would be the cost vs what’s the device on Mars cost? Also, I know plenty of solid engineers who I could build one thing based on that, obviously not taking atmosphere and G-forces into account to get there.

Also Linus finally got his progeny to Mars. That’s a pretty cool accomplishment:

“What have you built?”

Well, I invented one of the most prolific operating systems the world has ever seen, but not just this world - there is a helicopter on Mars that is flying due to the seeds which I planted that day...”

What have you built?

It's not just atmosphere and g-forces. The cold temperatures mean the helicopter spends 2/3 of its battery power keeping the batteries and electronics from freezing.

Good rundown of how it was built: https://www.youtube.com/watch?v=GhsZUZmJvaM
