<DIV>Putting it another way:</DIV>
<DIV>Monkey see, monkey do. In the Boat Drag Racing business, (and car
dragsters too) they had what was derisively called "The Trick of The Month
Club." Folks who succumbed to this club's allure, spent a lot of money and
then tried to make the latest trick work for them..Occasionally, it did
work. Most usually, it was a case of try, try again to get where you were
before trying this latest "Miracle Go Fast Gadget."</DIV>

<DIV>Competition breeds experimentation.</DIV>
<DIV> </DIV>
<DIV>Think back when Hanno Prettner showed up with an anhedral stab.
Pretty soon most of the designs had it. I remember hearing people say
that pattern planes would only fly well with anhedral stabs.</DIV>
<DIV> </DIV>
<DIV>Retracts. I made the comment at the '95 Nats that it no longer made
sense to have retracts on pattern planes. One fellow NSRCA board member
told me in no uncertain terms that fixed gear would completely screw up
the "force arrangement" of a pattern plane. Looks like one of us was
right.</DIV>
<DIV> </DIV>
<DIV>Airbrakes (another Hanno Prettner experiment). Next year, lots of
planes had airbrakes.</DIV>
<DIV> </DIV>
<DIV>Variable CG. In-flight variable pitch props. In-flight mixture
controls. Slow-roll buttons. Variable sweep wings. Winglets on the top
of a fuselage. Side force generators (yes, tried many years ago in
pattern - long before 3D ever existed).</DIV>
<DIV> </DIV>
<DIV>IMHO, simplicity wins most of the time.</DIV>
