My 206 is on AA high skids and I have a Paravion heliporter.
I have a barn with 3.44m clear access doors and beams running across at same height. I get the blades completely level before putting the machine away, using a front tie down installed first that is sized so that when you put a little tension on the rear, the blades are level.
It goes in with around 6 inches to spare, with the heliporter at full lift. I wouldn't go much lower on the height of the doors. And if I had a Chopper Spotter or similar, I would be in trouble as the front blade goes higher..
My aircraft came from the USA on dummy skids with mast and tailfin in place, in a standard 40' container.
