I Know of one owner who inverted his open top, cut the beam out and placed the container on a raised foundation of breeze blocks.
The doors had been extended with a draft excluder fitted and electrics plumbed in through the side of the container. He also tunnel groved the floor to allow run of from any spillage, this went into a collector for easy removal.
By using a simple electric winch place center rear with a long control lead he could pull the heli into and out of the hangar.
He controlled the back of the heli holding the tail skid area and used the helis own wheels. by placing a pulley at the oposite end of the landing area (in front of the hangar) and running the winch cable around it he could also pull the heli out.
Seemed to work. Just a thought!
