I was tremendously impressed and fascinated by the story behind the Kinetic and the Thundertaker. I have been following the adventures of the DS experts on RC Groups, and this story fills a lot of the blanks that I was wondering about. The design and construction of these planes is just magnificent (and so is the fact that they fly faster than 300 mph). Us thermal guys could get a lot of inspiration from the great work that Messrs Seim, Lisenby, Lilly, Manor and others are doing.
[RCSE] Gateway Open, August 22nd for HL, Aug 23 and 24 for Unlimited
Okay, OVSS aspirants and all you other sailplane lovers, the Gateway Open is fast approaching. The contest WILL be held at its traditional location, the Emerald View Turf Farm, Highway 79, O'Fallon MO. The flood made a mess of things, but the field has recovered. It isn't its usual beautiful green self, but there's enough grass to accommodate the contest, and the lift didn't get permanently dampened -- in fact, it's stronger than ever. I have to apologize to all for my own absence -- have to go to NYC for my son's birthday party. It kills me to miss our club's big annual event. But the guys you really care about WILL be there, the competition will be great, the air will be challenging, the food will be good -- what more could you want?! Plus you get to hang out with Glauco for a couple of days. HL on Friday 22nd, Unlimited on Sat and Sun. www.mvsaclub.com

Re: [RCSE] An argument for handlaunch.
- Original Message From: Ben Wilson <[EMAIL PROTECTED]> ...let me pitch you my argument for...better attention paid to handlaunch by soaring in general. Well, Ben, after hearing about how all you young bucks were having fun with these HL planes, I got me one of 'em and went to try 'er out. But I couldn't figger the dagnab thing out. First of all, there wasn't no towhook or nothin'. Then I noticed this little black popsicle stick jabbed through the end of one of the wings, and I thought maybe that was where I was spozed to hook on the winch line, but I couldn't get the ring to stay on. Daggondest thing I ever saw. And I got to thinking, even if I could, wouldn't the winch just yank 'er along sideways? So I give the whole thing up as a bad job and went to fly 'er on the slope, which she ain't too bad if the wind ain't a-blowin too strong. Maybe next time I see you, you can give me some pointers about what I'm doin' wrong.

I know the past few team selections, which timer you had was good for a 1 second difference in flight time == Mike's point may sound arcane, but it is actually central to ensuring the fairness of this event. I made this point after the 2006 and especially the 2004 WCs. An awful lot is decided by a few tenths of a second. There is an inherent error band in the timing of stopping the watch, and an even far greater error band in starting it. And there is the judgment call with respect to overflying the window, which Larry Jolly pointed out as a source of errors this year. In 2004, the WC top places were decided by an amount less than the possible timing error. The FAI rules committee should spend a little time talking to experts in statistics and quality control about how to tweak the rules so that the difference in pilot performance will be much greater than differences occasioned by the nerve pathways of the timer.

[RCSE] F3J WC results
Some other congratulations on F3J results are due: Andreas Herrig now has the remarkable distinction of having designed the airfoil for both the current F3B WC and the F3J WC. I don't know if anybody else has ever done that -- maybe Helmut Quabeck. Anyway, very cool. Dieter Perlick now has designed an F3J WC plane and an F3B WC plane, in different cycles. Also very cool. Samba had a streak of having built 3 consecutive F3J WC winning planes for the Seniors. That streak was broken, but the Junior was flying a Samba plane, so that's 4 WCs in a row. The designers and builders who work to advance the art are benefactors to all of us.

As all you Gateway Open aspirants know, the contest had to be rescheduled. There was talk of having it this coming weekend, June 28-29, but that isn't going to work because of continued flooding and other concerns. At this moment we are trying to shoot for August 23-24. That will be right in the thick of the OVSS final decisive contests. The WC guys will be back with their tales of conquest, and the thermals will be popping. So re-make your plans to meet us in St. Louis. No floods at that time of year, of that you may be sure. We had many emails from disappointed out-of-towners and we were disappointed too.

Two-day contest, part of the OVSS series, Saturday June 21 and Sunday June 22. Separate awards for each day, plus overall after Sunday's totals are figured. MOM, of course, 10-minute task time, landings similar to those at World Soaring Masters. 150-meter winch lines, a 60-acre sod farm with lush green grass for your landing pleasure. Glauco Lago, one of the 2007 Nats Soaring CDs, will be your CD, and the Mississippi Valley Soaring Association (www.mvsaclub.com) will be your hosts. For those old fogies like me who feel left out when Varios are banned, be advised that Varios will be legal at the Gateway Open. Now as to pop-offs!? Same rules as last year (fly 'em out). If the wind is 20+, the CD may allow one free pop-off per contestant. Lunch is included in the entry fee. Check our website for lots of info about us and our contests. What makes a great contest? Great flyers, waging a fair battle on a great field. That's what we have every year, and that's what we're gonna have this year. It's a chance to fly against the best, while you meet and greet your buddies from around the country. Flyers from 7 or 8 states attended last year including two who are on this year's F3J WC Team. Tiger Woods, Paris Hilton, and Elvis have been invited. U-2 will play during the lunch break. See you there.

Re: [RCSE] Airfoil flight comparison( HN-216)?
Richard, Norbert Habe's database (www.habebert.com) has a little summary data of all the airfoils he has designed, from HN-003 to HN-1091. The HN-216 is not included. It's possible that he did design it and it's just not listed, but it's also possible that some plane manufacturer chose this number to mislead buyers into thinking it's a Habe airfoil. Anyway, if you go to his site, there's a link that allows you to send him a request for the coordinates and/or polars. If you promise not to use them for commercial purposes, he'll send you the info (for example, I got it for the Espada airfoil when I got my RL). If he supplies polars, you can judge from that; if not, you can use Xfoil to figure out the answer to your question. If he didn't design the HN-216, then there's your answer.

Cal, I don't know about 3.5 but I have Realflight 4. It has no launch except handlaunch, but here's what you do. Use the flying field called "Thermal Park." There are arrows showing various air currents, including some pointing more or less straight up. Mouse around until the plane is pointing right at one of the up arrows, but don't point the nose of the plane up. Just give it a level launch onto the up arrow, and then start circling. You'll climb out. This is pretty cheesy, admittedly. The DS is really fun, however; even a novice like me can get in the groove and really scream.

[RCSE] recruiting new soaring enthusiasts
Original message: ...We simply have to do a better job of letting the public at large know we out here > Will it matter what the format is... if very few, if any, show up to > compete? ...it is pretty easy to get bored and wish for new contests > formats, I think it is very hard to recruit new guys to flying ... which > is the only way we are going to increase contest attendance. == This is the key point. The general contest practices have evolved to wide acceptance. To say that changing something will bring out new guys implies that there are lots of guys just itching to become soaring pilots but won't because they want different competition rules. We all know that's not likely. As I keep saying in posts here and elsewhere, our club has recruited numerous new members over the past couple of years, and activity and attendance continues to grow. There are a few key drivers of this growth: our website (www.mvsaclub.com); HL participation; and the availability of used moldies and excellent RES planes that allow a guy to get a really excellent plane plus radio for under a grand. The website, and our club's on-line discussion group, have been excellent sources of recruiting leads. When a guy does come out, usually with a wood-wing 2-meter, we don't urge him to come back over and over trying to learn how to winch the damn thing; instead, we try hard to get him to upgrade to a better plane as quickly as possible. This has worked in every case I can think of. We've added a half-dozen guys in their twenties and thirties, as well as older guys who are trying or re-trying soaring; virtually all of them have flown in club events, and the younger guys really love to throw those HLs. The club contests, and the trimming and preparation sessions for them, are a major focus of our club's activities (the website has a list of flying reports for recent fun-fly days, and you can see just how active our membership is). I can't say that it would work for every club in every locale, but for us the key has been that once a guy learns that he too can get a good launch, follow a thermal downwind, and stay up for a long time, he's hooked. Fun = airtime, and our focus is trying to show the new arrivals at the field how they can get a lot of airtime. To try to get more golfers out on the course they don't make the hole bigger or the greens fees cheaper; they sell the idea that you too can learn to play the game well enough to have fun. If what we are after is recruiting more enthusiasts, the success we'll have will be proportional to the number of young prospects who hear our message. The messages that you can get into it for a few bucks with a GL and some surgical tubing, or that the contests don't allow skegs, are not messages that excite anybody. The excitement comes from the thermals -- that's what we have to sell. "Young feller, you too can learn to fly one of these cool hi-tech machines that launches to cloud base and will ride thermals all day." Or: "Believe it or not, this 5-foot span plane weighs only 9 oz. and you too can throw it over a hundred feet in the air, and then by golly you can ride thermals all day. Costs a few bucks and takes some practice, but boy is it fun!" Make that pitch, make it to as many prospects as possible, and soaring will grow.
[RCSE] Contest Format
Original message: ...short of 10 minutes then zero flight points. Isn't that what all the top experts do in each contest. If you can't make the time, what makes you think you are good enough to get landing points either? === Which suggests a slight variation on the 10-9-8 etc. scheme: Only the maxers or round-winners get to go on to the next round -- everybody else is eliminated. That would really move things along.
[RCSE] Contest Format
Original message: ...To level the playing field and to reward players for not being prepared, less skilled or less practiced... = At first glance it appears to do that. But if you think about how this would have worked at contests you have attended, you might conclude that the overall effect is to introduce arbitrariness and quirky results into the scoring, with no corresponding benefit. It's purely a landing contest for the maxers; a guy who gets a near-max will have the door slammed on him with no chance to recover; and the guys who would have been at the bottom with conventional scoring will still be at the bottom.
[RCSE] Contest format
- Original Message ...Everybody who caught the air just flies past the target time and lands within the thirty seconds to collect their ten points == Still, you can have the odd situation where four guys make 10+, and one makes 9:59; if I understand it correctly, he gets a 6, the equivalent of 600 points, for a flight that should have been worth 999. The best way to avoid all these pathological outcomes is to normalize the scores. If you want to eliminate the precision, then just call every time over 10 minutes 10:00.
Re: [RCSE] Contest format
- Original Message From: Tim Bennett <[EMAIL PROTECTED]> ...in a "real" contest, 9 points or less out of ten, which corresponds to 900 or less out of 1000, is a low score. So what do you do when you have a typical OVSS field where 4 out of the 7 guys come within a couple of seconds of the max? One has 10:00, one has 10:01, one has 9:58, one has 9:57. You give them 10, 9, 8, 7 respectively? The same as if they scored 10, 9, 8, and 7 minutes? I don't think so.
[RCSE] Contest format
Original message: Your heart is in the right place for club events, but please do not do this at TNT... === Marc is right on. At a "real" contest, this sort of thing is fundamentally unfair. If everybody launches into the same air and one guy finds the air and gets max, while 6 out of 7 guys mess up and land early, they have to earn low scores, in fairness to everybody in the contest. The air was there and they blew their shot. Setting up some artificial scheme to pardon their failure is better policy for club contests than for the real thing -- sort of like allowing free popoffs.
[RCSE] Seeded MOM
(Original Message): ...I don't like...normalizing the scores. The idea of giving one man 1000 points for a flight while giving another flier half as many points for flying twice as long in a different group is morally wrongIn seeded MOM, normalizing isn't needed. That's already done by making you fly against your peers. If you don't normalize, it isn't MOM. It's called-flight-order, with all the ills of that ancient format that MOM was designed to cure (and does cure). The essence of MOM is that your skill is scored against the guys who launched at the same time. Ya know, this time of year there's always a lot of chatter about this or that contest rule. But the Nats, WSM, OVSS, F3J, and other big MOM contests have all settled on a pretty consistent format: 150 - 200 meter lines, seeded MOM, 10-minute targets, etc. Whether or not skegs are allowed never has the slightest impact on the scores of the top guys, although without skegs there can be some pretty scary landing dives and some damaged planes. The consistent growth of seeded MOM contests and the increasing standardization of the contest format is not necessarily a bad thing. The guys who fly a lot of contests seem pretty happy with the world of competition as they find it. The bottom line is, if you can outfly your group and you don't do too bad around the LZ, you'll do okay; and if not, not.

[RCSE] line tension
James MacLean wrote: ...I have given the auto line tensioner a bit of thoughta bang bang sort of controllerthe sensor...should be fairly simpleThe controller...a simple 4 bit micro and a FET or relay to control the winch solenoid = Yep, that's what I was thinking, Jim. The sensor wouldn't have to be fabricated; sensors are available commercially from various sources, including: http://www.tensionmeters.com/elec.htm#MPHB-Series,%20Base%20Mount,%20Three%20Tension%20Sensors The sensor needs to be mounted on a sturdy frame that can be staked down. That would have to be machined, but it's a simple part. The controller should allow for integration of the readings over a variable interval, and should have circuitry to introduce hysteresis so that it pulses the winch solenoid at a pace that doesn't overload anything. When you think about it, the electronics aren't complicated. This could, at least in theory, address lots of issues. If the gadgets turned out to be not too expensive, it might catch on.
[RCSE] line tension
There have been various proposals about limiting winch current via a series resistor, but nobody has mentioned directly governing line tension. It is certainly possible to devise a gizmo that would measure line tension, average it over some desired interval, and limit current flow to the winch so that line tension would be capped at some pre-determined amount. Commercial tension meters are common in industrial uses, and it would be straightforward to adapt their design to this purpose. If you broke the line while using this scheme, it definitely wouldn't be your fault, and you'd get a relaunch. Whether the pilot pulsed or not, the equipment wouldn't be overloaded. Every contest would provide identical launching power, and plane designers would know exactly what parameters to use in trying to optimize the plane's performance.
[RCSE] Insanity, PP, and plane size
Marc Gellart wrote: Hey Tony E., you are wrong about the largest ship to win the Nats. It was DP with his Insanity, 3.7M. == Yeah, I know. I didn't say the PP was the biggest. I just said it was the current WC and Nats Champ, and that it was 140", and that planes were getting pretty big, and I fancied an arms race that would end with everybody flying planes as big as a Schweitzer 1-26. The ensuing deluge of posts has explored this from many angles. Now one remedy du jour that's proposed is a resistor in series with the winch motor. Whatever the various merits or demerits of this idea, by golly, it would definitely make designers aim for an optimal balance between launch performance and glide performance, just as they have done in F3B. If the resistor was large enough (enough ohms, that is), we could go back to 200# line or even lighter. However, I have 2 PPs and I would be sad if CDs adopted a resistor whose value was so great that I couldn't get a good launch.
Re: [RCSE] Icon 2
- Original Message From: Darwin N. Barrie <[EMAIL PROTECTED]> ...My concern is the launching equipment. With the current crop of moldies, line breaks and winch bogging and ultimate failure are becoming more prevelant == I wonder about this too. The Pike Perfect is the current WC plane and the current Nats champ, at a bit over 140", and has apparently set a new benchmark that eclipses the 132" planes, which in turn pushed out the 3-meter (118") planes. It's all too easy to break the line with a PP, and line breaks will presumably be even more likely with 150" planes that have larger wing areas and can generate more pull. The 2-man tow setup puts a practical limit on F3J, but apparently that limit is not fully compatible with the standard U.S. winch setup; that is, it seems that the F3J scheme can launch bigger planes than our typical winches like to handle. One imagines a nightmare scenario where the planes keep getting bigger, and eventually as clubs need to replace their launch gear, they'll turn to super-power Injoy or similar winches, and the cycle will repeat, and finally we'll be flying models 40% of full-scale like the gas-power boys.
Re: [RCSE] Perfect on 50MHZ
Terry, I have two perfects on 50 mhz. They're not "full carbon," but that appellation applies to the wings. I think they have the same amount of carbon in the fuse layup as the full-carbon version. One is the standard version, the other the SL version. Anyway, I simply added 24" of wire to the end of the antenna, ran it through the fuse and out the back through the rudder opening. Range checks are great in all orientations and I flew both planes all last season with nary a glitch, no problems of any kind.

Re: [RCSE] Supra or Onyx JW, these are "Me-Too Designs"
- Original Message ... I presented my opinions as to what is a benchmark, and specifically stated my qualifications = This thread seems to be confused by the difference between the words "benchmark" and "landmark." Way back at the beginning, the original reference to a benchmark used the word correctly, viz. as a convenient standard for measurement or comparison. Various posters thereafter have gone off in the direction of trying to identify designs that had neat original ideas and significantly impacted later thought. The word for that is landmark. Libor is a benchmark; Marbury v Madison was a landmark. To say a plane floats better or worse or similarly to an Ava is to use an Ava as a benchmark. The speaker may or may not regard the Ava as a landmark design, but it's a convenient benchmark because everybody knows how an Ava flies. What constitutes a landmark is in the eye of the beholder. Roughly speaking, it's a design like the Fletcher or the JW-DS or the Allegro that looked unusual at the time but spawned a generation of similar planes.
Re: [RCSE] Supra History

[RCSE] albatrosses
The Dec 2007 National Geographic has a neat article on albatrosses. These soaring birds have spans up to 11 1/2 feet and cover as much as 500 miles per day, using dynamic soaring techniques to gain lift from the wind gradient above the waves. The article's description of how it works is not quite accurate, but the pictures, drawings and info are otherwise very cool. If you haven't thought about albatrosses since you read the Ancient Mariner in high school, this will be an eye-opener.

For those who have a bad taste about soaring competitions because they have been exposed only to open winch, give yourself a treat. Fly in a couple of OVSS contests and find out just how much fun you can have in this sport. We at MVSA switched our club contest format to MOM a couple of years ago, and here is what has happened: Participation has increased dramatically, with nearly double the total entries this year versus two years ago. We have attracted several new members. The standard of flying has improved sharply (two of our members won sizeable out-of-town contests this year, yet both of those guys were soundly beaten in the club standings). Activity on non-contest days has grown dramatically, with several members out to practice on just about any sunny day from spring to mid-winter. In short, MOM flying has made our club, and the soaring experience that we as members enjoy, better in every way. As a personal aside, I would add that I hadn't flown in non-club contests for many years, because I felt that in certain cases the reward in open-winch contests is less for flying and more for a certain type of behavior that I didn't want to engage in. After I flew in MOM a couple of times and realized that it was really a test of reading air and flying, I felt my old love of soaring coming back in full measure. Maybe the same would be true for others.

[RCSE] Sombra rx
I got a new Sombra programmable rx (www.sombralabs.com) from Barry Kennedy today. It's a double-conversion PPM unit that doesn't have a crystal; you program it to the desired channel with an external gizmo that plugs in, does its job, and then unplugs. The rx itself is a tiny board (8 grams) with the necessary connectors, an inductor potted in plastic to look sort of like a bypass capacitor, and (apparently) three ICs. One seems to be the front end/mixer, one (possibly) handles the two IFs, and one is a DSP chip. I'm guessing, of course, but I think that's it. The front end is hugely broad; my rx can be programmed across both the 50 and 53 mhz r/c frequencies, which sounds a bit alarming. However, the selectivity comes after the front end. Sensitivity is rated at better than 2 microvolts. There are no specs regarding adjacent channel rejection or such, so it'll be interesting to see what tests we users can do (Tom Hoopes, are you listening?). All I've done so far is to set it to 53.2 and range check it. Programming is a no-brainer, taking only a few seconds: set programmer, plug in, press button, remove. The range seems fine. I'll know more when I get it in a plane and give it a real try in the presence of other signals. If it works, it'll be a boon to those who fly on the ham frequencies. Of course, Sombra makes it for the 72 mhz band too, but I was particularly interested because my supply of ham receivers was interrupted. FMA used to make an 8-channel double-conversion rx for ham bands, but discontinued it and makes only a 6-ch now -- and it isn't the right 6 channels for my JR10x's 6-servo setup. Sombra has also announced a 9-channel xtal version coming next year. A lot of heavy-duty functions of a receiver can be done with ingenious DSP programming; ham transceivers from Icom, Yaesu and Ten-Tec have proved that. So even though this little board has no components that look like RF components, I'm willing to believe that it'll do the job. If so, it would be a great rx for any sailplane application, especially HLG. I'm optimistic. Barry or the sombra website can provide more details for those interested.

[RCSE] Matrix MOM
While sending out scoring spreadsheets for seeded MOM, I got a request for a spreadsheet to set up the flight groups for matrix MOM. I don't know how many are interested, since matrix MOM is not flown too often, but I thought I'd post this comment. There's no need for a computer to set up the flight groups for matrix MOM, since the process is easily done by hand. If there are frequency conflicts, it gets more complicated, and a computer program could be used to do optimal grouping, but let's stick to the simple case. The process is as follows: First, determine the number of flyers in each group. This will depend on the number of winches available. Then, give each flyer a unique identifying number, and set the groups by permuting the numbers. It's easiest to explain with a simple example. Suppose there are 16 flyers and you have four winches. Then you number the sixteen flyers like this: 1, 2, 3, 4, 10, 20, 30, 40, 100, 200, 300, 400, 1000, 2000, 3000, 4000. The first digit goes only up to 4 because there are 4 in a flight group. If there were to be 5 in a group, it would be 1, 2, 3, 4, 5, 10, 20, 30, 40, 50 etc. Then make as many numbers as possible that do not contain the same pair of digits. In this case, there are sixteen such numbers: Groups for round 1 1234234134124123Groups for round 2 1341241231234234Groups for round 3 1412212332344341Groups for round 4 To interpret this, read each digit as the ID number of a flyer. For example, the first group in round 4 is 1412. That means that it consists of flyer 1000, flyer 400, flyer 10 and flyer 2. You don't have any flyers with numbers containing more than four digits, so you can have only four rounds before you start having duplication in the groups. If you had twenty (or more) flyers, you could have five rounds, and so on. Of course, there are other four-digit numbers using 1, 2, 3, and 4, but they all contain one or more pairs of digits that are already used in the set shown (unless I made a mistake, which is certainly possible). With a little experimentation, you can see what happens if there are frequency conflicts, figure out the tradeoffs between group size and number of rounds, and so forth. You can see that it's easier to get conflict-free groups for a big contest than for a small one, because the number in a group is small compared to the number of flyers. Of course, small contests are usually flown as seeded MOM, so this isn't a problem. RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Top end speed in MPH ! Math quiz
Suppose the winch is spinning at 2500 rpm. The circumference of a 3" drum is 9.42 in, so the winch will pull in 2500 * 9.42 inches each minute. That means that the line would be moving at 22.3 mph along the ground. Of course, the drum diameter and/or the rpm are probably something different, but this sounds approximately right -- you see on tv that a dog can almost catch a fake rabbit pulled by a winch.Why then does the plane go so fast? Because its speed is a multiple of the line's ground speed, depending on the climb angle (the plane's airspeed is the ground speed of the line divided by the cosine of the launch angle). The steeper the climb, the faster the plane will be traveling. If the plane is climbing at 75 degrees, it's traveling at 86 mph. As the plane gets to the top and starts diving, the dive speed will be increased by the acceleration of gravity and the stored energy in the stretched line.You can make a rough guess at the plane's speed when it enters the zoom, as well as the amount of altitude gained in a zoom, by timing the duration of the zoom -- if it's vertical (if not, this doesn't work). At the WSM, I timed many zooms. For the moment, let's make a lot of simplifying assumptions. A vertical zoom that lasts 4 seconds will give up 4 * 32 ft/sec, or 128 ft/sec in velocity. If the ending velocity is 30 ft/sec, the plane had to start out at 158 ft/sec, or 108 mph. The average velocity is (30 + 158) / 2 or 94 ft/sec, so the plane gained 4 * 94 = 376 feet in the zoom.- Original Message From: RBurnoski <[EMAIL PROTECTED]>To: soaring@airage.comSent: Tuesday, September 26, 2006 10:03:25 AMSubject: [RCSE] Top end speed in MPH !

I know the drum gets bigger when the line is stacked. But, you can figure it both ways if your having a slow day. The question is: What is the maximum miles per hour that the winch will go pulling a 4 lb to a 6 lb model ? One other factor Im giving you. Im not talking about launching using the normal arc up over the turnaround. Im talking about a parrallel to the ground, from winch toward the turnaround scenerio. Thanks in advanced, Richard Burnoski
Re: [RCSE] Muncie - Soaring Masters Final Scores
---Original message--- From: Tom Broeski > Look at the age range of the flyoffs. Pretty wide. The old guys can't say > it's a young man's sport and the young can't say it's an old guy's sport. === Well, speaking as the oldest contestant (I think), I have to say that all of the flyoff participants, old and young, flew farther away than I could see. I can also say that at a certain point in your life, your timing in the launch process starts to get less accurate. That doesn't matter much in benign conditions, but it turned out to matter quite a lot in the strong and gusty conditions. Moreover, when your visual acuity isn't as good as it ought to be, you can't pick up the little changes in the plane's attitude and behavior that you need to see in order to surf in the kind of air we had. Actually, although the conditions were sometimes unpleasant, they were perfect for spreading the field and selecting the real masters. Young or old, those who scored well did it by outstandingly skillful flying. RCSE-List facilities provided by Model Airplane News.

[RCSE] Internal resistance of NiMH
- Original Message From: Brian Molloy <[EMAIL PROTECTED]> > High capacity does not necessarily equate to low internal > resistance That's the truth. The highest internal resistance of any pack I ever had is my 2700 mAH NiMH receiver pack (AA size). When you wiggle six servos at once, the voltage plummets, sometimes as low as to 3.9v; but it recovers immediately, and on a discharger the pack will deliver over 2.5 AH at a constant drain of 700 mA. Part of the way they get the super-high capacity is to powder the innards to the finest possible dust, and apparently this has a point of diminishing returns.

Re: [RCSE] AMA Rules and contest types
Jeff, Here's one for you. Our club once flew an event called SM1LE, standing for Simple Multitask 1-Lap Event. You launched into the wind, then went back behind the launch point. You then had a time limit by which you had to get on the course, which started near the launch point and went upwind. You flew up to the turn point, then back; after completing the course you finished out the rest of your duration task and landed. There were points for getting on the course, for the upwind leg, for the downwind leg, points based on how long it took to make the 1 lap, points for duration and landing points. The day we flew it there was a pretty stiff headwind. Not everybody completed the course and not everybody made the time, which I believe was 6 minutes. It's not automatic by any means to make 6 minutes when you have to follow a fixed flight course. The winner made it to the upwind mark quite low, caught a little hand-launch thermal, circled in it while still on the clock -- ruining his speed score, of course -- and drifted the length of the course. He then managed to fly out the time and hit his landing. It was an excellent event in my opinion but was never repeated because the way we ran it, with only one plane on course at a time, made it take too long -- we did only two rounds. Nonetheless, it was lots of fun to fly and fun to watch. It would be a real hoot to fly it with 4-man MOM flight groups! RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Re: Soaring V1 #8273
The pic of it is on the ESL site at http://www.flyesl.com/News-y-Articles/featured_article.asp?FORUM_ID=7&TOPIC_ID=221 I was intrigued too, and Anker Berg-Sonne described it to me in an email. The way it works is that you have a lineup of, say, four winches with chutes but no retrievers. Everybody launches. After the chutes land, there's somebody out there who runs around, grabs the chutes, and hooks them to the cart, then a winch winds the cart back to the launch line, and there’s a retriever operated by the chute-shagger to pull the cart out to him. - Original Message From: Ed Anderson <[EMAIL PROTECTED]> To: Soaring@airage.com Sent: Friday, September 15, 2006 9:04:08 AM Subject: [RCSE] Re: Soaring V1 #8273 Friends, I believe I saw a message that described how one club used a wood dolly on wheels to retrieve multiple winch lines during a contest.

Re: [RCSE] LSF discussion - some thoughts
I may be wrong (probably am), but perhaps some of the unease in the world could be mitigated by one little change in the LSF rules, without changing any tasks at all. The rules say: "requirements for the subsequent Levels may be achieved any time after the previous Level form has been postmarked..." So you can't get credit for Level III, IV or V tasks until everything in Level II is done and sent off, etc. Now just maybe if you relaxed this requirement, it might make some of the LSF dissidents happier. If a guy wanted to fly only thermal, for example, he could fly all his thermal tasks right up to the two-hour, and he could say, "Well, I have done the thermal requirements for Level V." Then maybe he'd be motivated to do some of the slope tasks, or the XC, or the contests or whatever. The LSF could even give out separate little stickers for thermal, slope, XC, and contests. This changes things very little, yet it addresses quite a few of the specific issues that have been raised on this thread. Now I've made my one and only comment, and I will now shut up.

Re: [RCSE] Re: LSF Discussion
Fellas, this has all been covered in the Weenie Manifesto as promulgated by the Weenies of Soaring and leaked to outsiders by someone on the Grand Weenie Council. You can go to the Yahoo soaring group where our archives are stored, Files section, and see a file there of a post from March 7, 2002 (weenie.pdf). Or click the following url: http://f1.grp.yahoofs.com/v1/4ET_ROkksrryW_mTtwDg1GQ3L--mI0QPaikArk9_CWfk9CZhJcfvJR9mXJmvjtsF2oU8zc4mTrVonZAI9xjsAG-8wkLWp6k/weenie.pdf The Weenie Manifesto, for those who don't remember, clarifies all that was wrong with our sport in 2002 and remains wrong today. Its three Articles are designed to straighten out the issues of expensive planes, unfair contest rules, and the present topic, viz., the LSF program. Article III is reprinted below for your delectation. Article III. Weenie Achievement We, the Weenies of Soaring, find nothing so preposterous as the endless list of tedious requirements for the various LSF levels. Why are the time requirements so long? Why not rethink the distance tasks so they can be accomplished without leaving the club field? The contest requirements are the most incomprehensible. A win is a win, no matter how many competitors were in the event or what their ability. Originally, we wished to demand that the LSF overhaul their outmoded and convoluted achievement program. However, we despair of ever talking sense to that stubborn organization. Therefore, we have adopted our own achievement program. We are proud to announce the Weenie Wings Soaring Achievement Award, which has not V but VI levels, thus immediately establishing its superiority over you-know-who. Every task is well within the ability of all Weenies of Soaring, and can be completed without inconvenience or discomfort, so we are certain that this award will quickly gain wide recognition and acceptance. For full details, see our website, and you'll soon be on your way to earning your own Weenie Wings. RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Re:Really practical ideas
From: [EMAIL PROTECTED] Subject: [RCSE] Re:Really practical ideas A hearty "Well Done" to the Long Island Silent Flyers for a very practical solution - quoting from their recent posting: "New to the contests are the Novice class, and Novices can register for FREE. Under 18 and Over 65 are also free for other classes." = Free entry is a great thing for newcomers, but it ain't magic. Our club (www.mvsaclub.com) has done this for the past couple of years, but at first they didn't exactly beat down the doors. However, this year we have had a flurry of new interest -- very exciting. It seems that there is an influx of new modelers brought into the R/C hobby by electric flight. Now some of these guys are showing up at our sailplane field. Electric foamy 3-D planes, flyable in soccer fields, have created a wave of young people with flying skills, and so have helicopters. One of the new arrivals at our sod farm was a charming young guy who looked at all the planes and asked a lot of questions; when we quizzed him, he said he had an electric heli. Upon further prodding he got it out of his car and hovered it inverted at 3 inches off the grass. The first time he tried flying a sailplane he promptly skied it out, then later landed it at his feet.. Anyway, it seems that there is hope for new blood in our sport. Remember, an even more powerful attractant than free contest entry is a friendly attitude. Be nice to your prospects, and they may become your key members of the future.

Re: [RCSE] how high really
From: Robert Samuels <[EMAIL PROTECTED]> if anyone out there can give us some research based information on far a human can discern an object like a 3m sailplane I'd sure like to hear it. == Well, it depends on lighting and contrast. For resolving front-lit objects like lines on a page, various sources say that the human eye can resolve a pair of parallel lines that subtend 1 or 2 arc minutes (let's say 2 to be conservative). That means that if you had two parallel lines 10 feet apart, the best human vision could tell that there were two lines and not a single line if the pair were 17000 feet away! When you look at stars against a black sky, you can resolve smaller arcs. Some exceptionally gifted people can resolve Jupiter and one of its moons, or the North Star and its twin (there are actually 2 stars there, 18 arc-seconds apart. There's a third too, but only Hubble can see it). But seeing a wing against the sky depends not on the span, but on the chord. If the chord is 1 foot, it will subtend 2 arc-seconds at 1700 feet. The contrast is better than that of front-lit lines on a page, of course, so the eye can keep going. At 3400 feet, the 1-foot chord wing subtends 1 arc-second. Only really good eyes can see that, and it will be dependent on the brightness and character of the background. As you go on from there, you're surely getting to the limit of most people's vision. Both Babe Ruth (on his best day) and Albert Pujols have been reported to have 20/7 vision, almost 3x as acute as that of the poor middle-aged glider flyer. Perhaps if you want an altitude record, you could catch Albert on his day off to help spot the plane. RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Foil Wing Bags
...bubbles as in bubble wrap. The bubbles contain Air, trapped air will continue to get warmer as the sun hits the surface. = Air is a pretty good insulator. The insulating properties of your fiberglass mat home insulation, the down in your sleeping bag, the foam in your cooler and the thinsulate in your ski suit are all attributable mainly to the trapped air. The solid material provides loft to maximize the volume of the trapped air, and baffling to stop the air from circulating via convection. The thermal conductivity of air is less than the majority of solid materials. The insulating ability of a most common insulation materials is more or less proportional to the ratio of empty space to solid material. Down is such an effective insulator because the quasi-fractal structure of the little branching feathers means that a small amount of solid material can puff out a lot of volume and provide very effective baffling.

Re: [RCSE] Super AVA airfoil
I repaired my Ava and later traded it to my flying buddy Glauco Lago. He then did some more repairs. In the process, he and I both made ribs for the plane, so I know we figured out the airfoil; but it isn't what I said in my previous post.Glauco just reminded me that the Ava airfoil is not a match for the AG35 as I said it was. Specifically, the Ava has undercamber and the AG35 is flat-bottomed. Still, I remember that the Ava had what appeared to be a thickened version of some Drela airfoil - more or less. Maybe it's a thick AG16 (compufoil file at http://www.charlesriverrc.org/articles/drelaairfoils/AG16.COR). The AG16 is less than 9% thick and the Ava is roughly 10% thick if memory serves - you can easily figure out what thickness you need.
Re: [RCSE] Super AVA airfoil
Try the AG35 (http://www.charlesriverrc.org/articles/drelaairfoils/ag35.dat)That's the design airfoil. On my older Ava the actual airfoil was pretty close to the AG35 but a little bit thicker.
