I only rarely have the opportunity to photograph a helicopter from the inside, but I'm trying...

Mil Mi-1
Mil Mi-2
Mil Mi-8
Mil Mi-24
Robinson R44

Mi-1

An oldtimer, I photographed this in the AF museum at Szolnok.
 

Mil Mi-2

The only helicopter I had a flight with...
 

Mi-8

Not to complicated ;-)
 

Mi-24 "Hind"

Well, if you thought helicopters had very few instruments, gauges, buttons, switches, handles and levers, take a look at the Mi-24 gunship!

(And that's just the pilot's working place, the weapon systems operator sits in another cabin!)
 

Robinson R44

HA-MIW: almost as simple as the cockpit of a glider - at least in contrast to the Mi-24 :-)
