<DIV><SPAN style="COLOR: black; FONT-FAMILY: 'Arial', 'sans-serif'">I fly IMAC Intermediate class since many years ago. Probably 1-2 contest per year because contest is too far from KC. Jim is very close in his description. However, I found that if you fly with the same goals we fly in pattern you will have very high chance to win in IMAC. The rules are very close (read the snap roll and you will be surprised how close is to pattern AMA and F3A, IMAC and IAC). I think the Sportsman’s IMAC pilots get stuck in that class because they have to fly partial rollers in Intermediate IMAC without learning to do slow roll first. Looks like IMAC don't want to do slow roll because is a pattern maneuver. If you check the IAC maneuvers you will find that they have slow roll. In conclusion, I believe we have very close goals but we are always looking for ways to find differences when
really there is not a huge difference after we read the rulebooks. </SPAN></DIV>

<DIV><SPAN style="COLOR: black; FONT-FAMILY: 'Arial', 'sans-serif'">By the way, I am using soft mount in my YAK (DA 100 with canisters and 3 lade prop). One time I got to a contest and started the engine to get ready. A couple of pilots in the other side of the field came to ask me if my motor was electric. IMAC guys do not use soft mounts just because pattern guys use soft mounts. It is similar to the elimination of center manuevers to the judges. The excuse to eliminate center manuevers was because IMAC goal is to reduce the footprint. However, I don't understand how you reduce the footprint without doing the center manuever in the center. Go and figure. <BR><BR>Vicente "Vince" Bortone</SPAN></DIV>

IMAC<BR>> versus pattern? <BR>> <BR>> <BR>> <BR>> I’ve flown a bunch of<BR>> IMAC over the last 4 years. <BR>> IMAC and Pattern answer two different questions, and each<BR>> group has DISTINCTLY different<BR>> personalities. At the end of a pattern contest, you<BR>> will see who flew the<BR>> sequences the best (usually the best pilot). At the<BR>> end of an IMAC<BR>> contest, you will get closer to seeing who the best pilot<BR>> is in that<BR>> class. There are pros and cons for each, each fitting<BR>> the personalities<BR>> of the groups. <BR>> <BR>> <BR>> <BR>> Pattern: Is about<BR>>
learning the fundamentals of precision<BR>> flight. Group is not too excited about changing sequences<BR>> too often, especially<BR>> for the lower classes. It is a pattern-truth that the<BR>> lower classes are<BR>> designed to build piloting skill and teach precision<BR>> aerobatics fundamentals<BR>> (wings level and such). This group recognizes that<BR>> guys don’t get<BR>> to fly every day, and the goal is “fly your sequence<BR>> the best you can.” <BR>> Lower classes are not considered “destination”<BR>> classes. <BR>> Pattern guys almost 100% of the time can get into Advanced<BR>> and Masters, with<BR>> F3A being hit or miss. Pattern guys believe it is<BR>> “fair” that<BR>> the competition is only the “known”<BR>> sequences because this<BR>> levels the playing field – anyone can compete because<BR>> we know what is<BR>> going to be
flown ahead of time, and the tier-2 kind of<BR>> pilot has a competitive<BR>> chance against tier-1 pilot, per se’. <BR>> Pattern guys want to<BR>> know what the rules are, and then build a plane within the<BR>> rules and maximize<BR>> what they can. Pattern guys are open, and keep all<BR>> contests open to<BR>> whoever can make it. <BR>> <BR>> <BR>> <BR>> IMAC: almost 100%<BR>> opposite to the pattern<BR>> personality. Guys don’t like rules! Do<BR>> not want rules applied<BR>> to planes (… no support for even adequate mufflers or<BR>> tuned<BR>> pipes/silencers). Not willing to “describe”<BR>> airspace or where<BR>> maneuvers are flown (read ACS definition if like and let us<BR>> know what the criteria<BR>> is). IMAC does not encourage moving up in the way the<BR>> culture of pattern<BR>> does – plenty of guys in
IMAC will fly Basic or<BR>> Sportsman for many<BR>> years. Intermediate is realistically the destination<BR>> class. Few<BR>> make it into Advanced, and less into Unlimited. IMAC<BR>> guys want to fly new<BR>> sequences every year, and this sort of offsets the<BR>> motivation for moving<BR>> up. IMAC guys have some affinity for<BR>> “freestyle” and<BR>> undisciplined flying – they like that you don’t<BR>> have to practice<BR>> the know sequence all the time. All you need to do is<BR>> keep “close”<BR>> in the knowns, and score a high unknown round and you can<BR>> win the contest due<BR>> to the higher weighting the unknown round carries. <BR>> IMAC guys don’t<BR>> really focus on getting better geometry out of<BR>> maneuvers - as hitting<BR>> snap rolls will make or break you IMAC score. Using<BR>> the 0.5/point per 5<BR>>
degree rule, “snap-rolls” are in fact the whole<BR>> secret to scoring<BR>> IMAC patterns well – it is a maneuver within a<BR>> maneuver and you need to<BR>> learn how your plane snaps at low speed, high speed,<BR>> power-on, and<BR>> power-off. If you can’t hit a snap roll exit,<BR>> don’t even<BR>> think about getting into Advanced or Unlimited. This<BR>> group likes “exclusivity”<BR>> or “invitational” events, and this also makes<BR>> its way into the<BR>> regional championships. <BR>> <BR>> <BR>> <BR>> So – there are totally<BR>> different personalities at work for<BR>> both organizations. I like flying unknowns, but I<BR>> don’t think it is<BR>> a good mix for precision aerobatics events. <BR>> Guys moved from F3A into<BR>> Masters to get away from the two known sequences, so I<BR>> don’t think<BR>>
unknowns for the AMA classes really fits into the culture,<BR>> or our goals of “precision”<BR>> aerobatics. <BR>> <BR>> Thanks, <BR>> <BR>> Jim <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> From:<BR>> <A class=moz-txt-link-abbreviated href="http://us.mc805.mail.yahoo.com/mc/compose?to=nsrca-discussion-bounces@lists.nsrca.org" target=_blank rel=nofollow ymailto="mailto:nsrca-discussion-bounces@lists.nsrca.org">nsrca-discussion-bounces@lists.nsrca.org</A><BR>> [<A class=moz-txt-link-freetext href="http://us.mc805.mail.yahoo.com/mc/compose?to=nsrca-discussion-bounces@lists.nsrca.org" target=_blank rel=nofollow ymailto="mailto:nsrca-discussion-bounces@lists.nsrca.org">mailto:nsrca-discussion-bounces@lists.nsrca.org</A>] On<BR>> Behalf Of Anthony<BR>> Romano<BR>> <BR>> Sent: Tuesday, September 22, 2009 8:50
