TWN,
I understand your issues with rubberbands but in this particular instance it works just fine. Not the most aesthetic solution but it works fine and I don't see the retaining wire coming out even if the rubber band were not there at all. I'm flying mine with an OS 1.08 and have had no issues with the stab. I'm generally a warbird flyer and not an aerobatic or 3D type flyer but the Ultimate is a great airplane to just sport fly and keep the thumbs nimble with.
