The tail is not self furling. Yes it's on center on a straight hinge. I'm using farm hay rake springs to keep it straight when flying. The springs hold it out like the old Winchargers. The cable, pulled from the boat winch at the bottom of the tower, over comes the spring to park the machine with tail folded. Quick wind direction changes in one direction actually pushes the tail against the springs and dampens the movement, which I didn't expect but I like it now that I've seen it in fast changing winds. The other direction just keep the tail against the stop. Dave M.
