I am in Auckland with a good friend who is building a gyrocopter. His doors are similar in shape to those on an SR2X. He is now working on the hinge arrangement for his own doors, and I am trying (unsuccessfully) to describe what it looks like on our 'planes.
If you have a photo of your hinges (or, if you have a digital camera, and you feel like doing a favor for us), I’d appreciate any pics that might help get the idea across. Please email what you have.
