This helicopter gives tours of the Hoover dam and probally spends more time on the ground running than actually flying.
I was wondering what the dark spots on the rotors were, and then noticed they lined up with the exhaust pipe, is this normal?

probably just exhaust gunk (carbon, etc) like you suspected. Looks like it's in the right "pattern" for that kinda thing.

If that was a car engine I'd say it's not running the greatest (burning oil or running rich) but I don't know anything about helicopter engines so...

Yup, Exhaust Soot...

Looks like a solid glide ratio. ;)

Don't worry about the black on the blades. That guy is in big trouble, the rotor has quit turning! :lol:

you should see the black tips on the horizontal stab of a Twin Otter... or even the nacelles on a King Air. nice black arcs down either side all the way to the trailing edge sometimes.
