According to the Flexheads literature, the min bend radius is 3" for UL and 7" for FM. An experienced fitter once told me allow 10". Based on that and figuring you need to make 2 bends with some overlap, I would say 15-18" would be a good number. It's not going to bend in a simple "over and down" arrangement but in whatever curve naturally forms with the least stress.
