If Bill hadn't said what he said I would have said "Hell No!" Even with his testimony, I think I'd weigh the relative danger of landing gear not coming down vs. flaps failing at some arbitrary part of the pattern (i.e., straight down and 15 feet off the deck), and then I'd use a conventional ball link.
Take-apart models that have the wings plug into the fuselage leave the flap horn pivoted firmly on the fuse -- I'm not sure what folks usually do, but I expect that they either have a deep notch in the end of the flap (like a lucky box left open on the fuselage side) or they have removable flaps that slide off of the flap horns. Are you taking your plane apart somewhere else?
