The aircraft is an Aerospatiale AStar (Écureuil), each rotors are attached by 2 pins, and are indexed such that they can be removed and reinstalled without any change to the rotor balance. I spent a previous life hanging out of one of those tweaking geophysical instruments, and we regularly took the blades off to push the aircraft into the hanger.
Don't know what the payload is though, you'll have to ask 672. Our birds never looked that nice...
