I love how maneuverable these things are.

The pucker factor is high with this one.

That is the single most effed up rotor system ever devised. I'm an ME and have always tested good for spatial reasoning. I cannot figure out how those rotors don't crash into each other. Logically I understand it, but every time I see a picture of that setup instinct just screams that they're going to crash into each other.

Think of it like an automatic mixer that most people have in their kitchens. the beaters intermesh, but don't collide.

If they were independently free-rotating, perhaps they could hit, but they are locked together.

If they are fixed to each other at a 90 degree angle from each other, such as through a gear set, or other interlocked drive system. They have as much chance of hitting each other as an interference engine's valves and pistons. As long as the timing drive mechanism stays intact, the parts don't occupy the same space at the same time.

Logically I realize and understand this. Instinctually when I see a picture my first thought is that it can never work.

What blows my mind is how capable this tiny chopper is. It can lift a ton of mass

Think that's bad. How would you have liked to be the test pilot of the first airplane that had a machine gun firing through the props?

Synchronizing gears FTW. Still would have been very unnerving pulling the trigger.

I can't get my head around having a payload weight greater than the empty weight. That is impressive.

Keep in mind that until the figured out how to synchronize between the engine and trigger mechanism, the solution was to rely on luck or armor the propeller! Note the bullet damage to this propeller:
