I have a standard garage door. I just get a couple of friends to help me move the gyro in and out side ways. It rolls on one main but the whole aircraft is about at a 70 degree angle. Of course the ceiling of my garage inside had to be tall enough, but that wasn't an issue for me once I got passed the door.
It's a little inconvenient since I can't move it by myself, but I've done with just one other person in a pinch. Three people is better.
