<DIV>Richard, that could be true, BUT I don belief that. Hanno Prettner and
his father Hans did not leave things to happen by luck. If it was not right, he
would make it right. All great Champion are like that. He has to design that
like that for a reason</DIV>

<DIV><SPAN class=082573103-01012005>I heard that Prettner felt that he needed
to lower the stab to get it out of the wing's wake and did not want to
cut it out and reinstall it so simply cut the two halves off and glued them
back on at a downward angle. I built and flew Hobby Barn glass fuse, foam
wing Curare back then when I was just getting started in Sportsman. I
thought the anhedral stabs looked very cool. I also heard that these planes
had tracking problems in crosswinds because the stabs presented more side
area to the wind which caused the tail to bounce around
more. </SPAN></DIV>

<DIV>Matt,</DIV>
<DIV> </DIV>
<DIV>You were close. The year was 1977 and the location was Springfield,
Ohio.</DIV>
<DIV>That was the year a twister went through the competition site the night
before</DIV>
<DIV>and tore down, among other things, one of the tents that was used
to store </DIV>
<DIV>the models in. It was quite a mess, but the contest went ahead as
scheduled.</DIV>

<DIV>Anhedral stabs are affected by crosswind more than flat stabs. At
least for the kind of flying we demand. The Prettner Curare design, World
Champ around 1976 or so, introduced the feature to models. By virtue of
its being World Champion model, everybody copied it. Sort of the way fixed
gear took over from retracts, except fixed gear have persisted far longer
and serve the intended purpose well. </DIV>
<DIV> </DIV>
<DIV>Curares and other anhedral stab designs flew well into the 80's but
eventually the fad died down. </DIV>
<DIV> </DIV>
<DIV>Naruke san is possibly trying to cure some aerodynamic inadequacy by
employing the feature again. Or maybe just likes the look. It does look
Kool as hell. I doubt that this is a revolution though; more like
evolution....in
reverse</DIV></DIV></FONT></BLOCKQUOTE></BLOCKQUOTE></FONT></BLOCKQUOTE></DIV>
