Sorry, I should have posted that on this site as well. Later, when I get to a computer, I will. When I spoke to Shane and Russell at airborne they were quite insistent about checking for a gap and closing it if there was one. To quite Shane, "the sst is horrible to fly if there is a gap between the mast and the hangpoint bracket". It amazes me that they rely on a washer between the wing nut and the hang bracket to ensure enough tension is present on the bracket to close the gap. $70000 and it doesn't fly right if you lose the washer?
Bluey.
