I would think in this case "assembly" involved taking the helicopter of the shipping skid , assembling landing gear , perhaps MGB and TGB , main and tail rotors and rigging the flight controls . I think assembling any helicopter in 36 hrs ( Robbies included ) would be a tough feat even for Toyota.( or the Indian equivalent ). I am trying to imagine a conversation between a texan pilot and outsourced indian Bell Product support . 'why is there a turban on your helicopter ?"
