<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><DIV>Some planes were breakthroughs just because they broke the mold. I would put the Astro Hog in that category. Most others took advantage in advancements in technology. I would put the Bootlegger in that category (tuned pipe internal instead of hanging outside). </DIV>
<DIV> </DIV>
<DIV>One plane that has already been mentioned is the Mach I. This advanced pattern into the ballistic age. The thin wing and really streamlined fuselage.... beautiful.</DIV>
<DIV> </DIV>
<DIV>Someone already mentioned the Focus. What was breakthrough about that was not the design per se, but the fact that it was an affordable ARF that could be built easily yet could (and did) win the NATS. Up until then, you had to pay an arm and a leg for a plane that probably required a LOT of work to be competitive.</DIV>
<DIV> </DIV>
<DIV>Elements of technology that changed pattern: Digital proportional radios; Retracts; Schneurle ported engines; Tuned pipes; Four-strokes (ok, that was a rule thing, but still...). Lipo batteries made electric pattern not only possible, but competitive.</DIV>
<DIV> </DIV>
<DIV>I think the biggest changes (won't really call it 'breakthrough') have been the rules. Pattern planes could have been larger than they were had it not been for the limit in engine size. The story I heard was that Duke Fox designed the .78 for pattern, but then they came up with a rule to limit the engine size to .61. Then the rule to allow up to 1.20 four-strokes due to the 'power disparity'. (???) Then came turnaround, and the designs were forced to change. Then the unlimited engine size. I've always said that a lot of manufacturers shy away from pattern since it has always been a moving target. </DIV>
<DIV> </DIV>
<DIV>I have to think back to Tom Miller's "Reaction" design. It did not have much impact on the sport, probably because it was too far ahead of its time. Back when guys were still flying ballistic planes with 2 strokes, tuned pipes and retracts, here he comes with a fixed gear, taildragger, fat fuselage (relative to the times), four-stroke plane and said "this is where we are headed". Give that man a prize!!!</DIV>
<DIV> </DIV>
<DIV>And the beat goes on....</DIV>

<P class=MsoNormal><SPAN style="FONT-SIZE: 11pt; COLOR: #1f497d; FONT-FAMILY: 'Calibri', 'sans-serif'">What do you think were some of the most breakthrough or pivotal pattern designs? When I started there the Prophecy was top dog. A couple years later the Smaragd was designed. I see a lot of planes have been designed off the Smaragd platform. I think the PassPort is a heck of a plane.</SPAN></DIV>
