<DIV><FONT face=Arial size=2>2 years ago, some of us pattern nuts in D3
witnessed the most incredible thing in Nashville at a contest. Levi Simms, an
intermediate pilot, took off with his Prophecy and began practicing for the
day's rounds. He made it through about half of the sequence, then pushed over
the top to set up for his outside loop. At this time, one of the wings
disengaged from the adjusters and turned 90 degrees into the air stream.

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>After everybody gasped and the usual "oh #&@*"
remarks, the plane went into a spin....a soft helicopter like motion. The
descent was very slow, and he found that by adding power, he could SLOW the
descent even more. To make a long story short, the plane went in, and didn't
even break the prop....from about 100 feet or better.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>He had forgotten to install the screw into the wing
tube, and made half the flight with the wings just stuck on. He put it back
together and flew the whole contest without incident. Now for obvious reasons,
he's known as "Lucky Levi".</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So the point is, there's not a lot of outward force
on the wings at all. So for anyone worried about making that attach screw
survive a nuclear blast, don't worry...it's not NEARLY as critical as it would
seem. Just remember to screw it in before you fly =)</FONT></DIV>

<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>Anyone out there actually calculated (or
measured) how much OUTWARD force is exerted on our wings during our typical
stuff? I'm looking for the force in line with the wing tube, spanwise,
for the "retaining" load to keep the wings ATTACHED.....</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any knowledge?</FONT></DIV><FONT face=Arial
