RE: Updated Weight Requirements?
I'm not sure if anyone has gone and read the new proposal, but here's a link to it: http://modelaircraft.org/files/RCA11-10Fuqua.doc While I think the only "problems" that need to be fixed with the current weight rule is to clear up the fact that 11 pounds does not equal 5 Kg and to allow for scale inaccuracy, this rule does both plus gives a little leeway to the lower classes. The only issue I have with this proposal is that sportsman should just be exempted from the weight and size rules altogether. Most CD's announce ahead of time that this will be the case anyway, and sportsman isn't flown at the Nats. I can see the 115 grams for Intermediate, but not Advanced. I also like that they left Masters without the 115 gram leeway. By the time you're at that level of competition you've committed enough and you should know enough to be able to make weight. Of all the proposals I've seen, this is one I could actually get behind. I think the committee did an excellent job on this.

RE: Canalisers, fins and things, and whirlygigs..
By sensitivity they mean the "touchiness" around neutral, authority is referring to the power at full deflection. For instance, the strake that Bryan Hebert developed for the Valiant (Jason's first picture) was done because he didn't feel the rudder had enough power for stall turns.

RE: Cajun Nationals Crowley, LA. Oct 24 & 25
OK, I see the picture of the presenter of the Ray Rhodes trophy, but do we have any pictures of Buddy with it? For those outside of District 6, Jim Thompson and his wife began sponsoring the Ray Rhodes Memorial trophy a few years ago to honor the individual each year in District 6 who, in the eyes of the contest directors, has made the biggest impact on growing pattern in District 6. This year's recipient was Buddy Brammer, a well-deserved honor in my opinion. Buddy is just one of those all-around great guys, willing to help anyone, who really represents pattern well.

RE: Patriot Bites the Dust
[quote]ORIGINAL: jamesg33 I always attributed it to the plane, as I had to double back the antenna in the fuselage (the radio gear in the Patriot is just forward of the horizontal tail) and none of my other planes have had problems (but they'e all on other channels). [/quote] On the rebuild you may want to consider repositioning your receiver at least. Doubling back on the antenna effectively reduces the length, causing reception issues. The length of the antenna is specific to the 72 MHz (or 2.4 GHz) frequencies, and shortening it will reduce the range.

[quote]Ok, just wondering about something. It is often said that AMA is a benefit to the modeling community beyond just the members of AMA. Since the members and clubs are our greatest visible assets to engage the community at large…what have you or your club done to benefit the rest of the modeling community…you know, other than the club or AMA members? [/quote] Look at this article from Model Aviation, December 1992. This is the kind of stuff the club my dad formed used to do. The club isn't around anymore due to loss of flying sites, but this is a fine example of the kinds of things clubs all around the country do to reach out to the community. I was there that day, and it was a very heartwarming experience. The kids had a blast, and it was the highlight of their week!

RE: Help, plane has a mind of it's own.
[quote]ORIGINAL: opjose That assumes that there is a problem to begin with. The article tells how even in properly set up airplanes, adding the tip weight improves the characteristics of the plane, and also gives the reasons why this is so. That has nothing to do with ''mediocre'' pilots, nor lack of skill in flying a scale model. [/quote] Are you saying my opinion is wrong? From my point of view, if you need to imbalace your airplane laterally to overcome characteristics that you can't otherwise overcome with the controls, then you're a mediocre pilot. One man's opinion. I didn't state it as fact.

RE: Help, plane has a mind of it's own.
I finally got around to trying to read the article from MA that everyone keeps bringing up. I got about 4 paragraphs in and stopped reading. I think articles like that are irresponsible because it encourages mediocre pilots to stay mediocre and come up with band-aids to overcome their lack of skill or understanding of how to properly fly a scale model.

RE: F3A Judges Corner . . ask a question
[quote]ORIGINAL: Magne This may be a language thing (I am Norwegian) but how do you guys define pitch break? Whether I fly my F3A model horizontally, vertically up, vertically down, or any other angle for that matter and suddenly apply full up (or down) elevator, the model does NOT stall, it just initiates a section of a loop. The stall in a ''snap'' only occures after I apply aileron and rudder. So the sentence ''since the model aircraft is supposed to be in a stalled condition throughout the manoeuvre'' seems to me to be impossible to achieve, as the manoeuvre starts with a (small) section of a loop. I have never flown an F3A/pattern model that stalls (at flying speeds) by applying elevator. If I were to initiate a ''snap'' by applying full elevator, and did not follow up by applying aileron and rudder, then the model would simply loop, not stall. Please clarify. Full size aerobatic planes, different story altogether. Magne [/quote] Magne, you just identified a fundamental issue with snaps in pattern, or at least as defined by the FAI. I don't think it's a language issue. When I do snaps I try to give the elevator input immediately prior to the aileron/rudder input so that the nose pitches up but I start the rotation before it has a chance to deviate (much) from the line. All this argument is why I think snaps have no place in pattern. They're not precise and therefore have no place in precision aerobatics.

RE: F3A Judges Corner . . ask a question
[quote]ORIGINAL: twoturnspin My issue is that I don't know a break and ''separation from the flight path occured'', therefore maybe it didn't snap. If the tail describes a cone, then the nose must move in the same arc (assuming it is rotating on the C of G) does that constitute a snap? On this basis you can do a snap using aileron and rudder only because this will cause the ''cone'' to occur without application of elevator. If this is the case, and I will only lose one point because the break occured simultaneously with the start of rotation, I'm changing my technique! The one point sacrifice will almost always offset the downgrades that tend to arise from using substantial elevator to enter the snap. I just think this perspective is against the intent of what a snap is. Would love to hear the thoughts on others on this. Can I just use rudder and aileron on a snap so long as I create a cone shape at the tail? Simon [/quote] If the wing is not stalled the airplane will barrel roll on application of just rudder and aileron. The "cone" shape scribed by the tail and nose in a proper snap as the airplane autorotates around the CG is an indication that the wing is in fact stalled. If the separation from flight path occurs simultaneously with or immediately after initiation of the rotation it may not fit the definition that requires the pitch break prior to rotation but it also does not meet the criteria for severe downgrade because the airplane did not barrel roll. Again, this is just my interpretation of the rule, but if the FAI wants it interpreted differently they need to re-write it. My first name is Matt by the way. I don't use it on here often because it's so common and there are likely other "Matts" following this thread.

RE: F3A Judges Corner . . ask a question
[quote]ORIGINAL: twoturnspin Pilot A: No break, severe downgrade - score 4 [/quote] I disagree with this assessment because the way the rule is written it says "If the stall/break does not occur and the model aircraft barrel rolls around, the manoeuvre must be severely downgraded." The key to this statement from a rules standpoint is the use of the word "and". Merely failing to observe the break does not justify the severe downgrade, the break must not be observed AND the airplane must barrel roll, then there must be a severe downgrade. Lack of a barrel roll indicates that a stall break must have occured at some point because the tail scribed a cone. That's why I gave a 9 to this one based on the assumption that the break occurred either simultaneously with or immediately after the rotation. Apply the 1-point per 15 rule, and since no partial points are allowed in F3A and the observed maneuver was obviously not perfect, I give a 9. I prefer the AMA description because it allows for simultaneous break along with the rotation.
