Here's a silly question: Is there any way to convert a t-hangar's
manually opening bi-fold door to a motorized one?

I just rented a t-hangar that uses a circular chain hanging off a large
pulley near the top of the hangar to control the door. The chain must
be pulled thirty to forty times to fully open or close the bi-fold door.

Perhaps some type of conversion to an automatic garage door opener?

Has anyone ever done anything like this?

Or ditch the stupid crappy bi fold completely and get a hydroswing to
really go first class.
