FROM THE EDITOR – Ed Anderson

Welcome to the March 2011 Eastern Soaring League Newsletter and the 2011 Eastern Soaring League season. This first newsletter is packed with articles and informational references that I hope you will find interesting and useful.

We start with a greeting from our new President, Josh Glaab, and then take a look at the ESL calendar for 2011. I think this is the largest number of contests I have seen since I joined the ESL seven years ago. We also have featured articles about the first two contests this year so be sure to read those. And Josh provides an historical look at the evolution of the ESL and how it has developed into what we know today.

There are numerous reference links to resources and points of interest on the web. These include tips on where to stay at the contests, the F3B team web site, the AMA soaring rules book, videos of top competition pilots in practice, building tips, radio set-up tips and more. And I have included a few that are just there for fun.

I hope you enjoy this edition of the ESL Newsletter. And I hope to publish some of your photos, articles and contest reports in future editions.


FROM THE PRESIDENT – Josh Glaab

At this time the start of the 2011 ESL season is only about 2 months away! I am looking forward to seeing many of you in Waynesboro on May 13th, 14th, and 15th. All indications are that the 2011 season will be even better than 2010 with 18 Unlimited competition days and 16 for HLG! Lots of flying for sure!.

Doug Harnish and Jose Bruzual have done a nice job in the off season coordinating the HLG events and I appreciate their work for sure. It also sounds like there is some increased interest in showing-up and representing the ESL at the US Soaring NATS. One feature of the NATS this year will be the two-day F3J contest that occurs after unlimited. The F3J competition will allow winch-launches or F3J human-tow depending on how the team would like to launch. This should help get some more flyers interested in that part of the contest.

Please let me know if you are interested in F3J at the NATS. The simultaneous launching and landing of F3J is different than normal MOM thermal duration. Taken together, that would be 4 consecutive days of unlimited competition flying.

Prior to Unlimited there will be 2M and HLG. It is neat that HLG is just before Unlimited. However, I assume we will be testing 2.4 to some extent with HLG and 2M flight-groups up simultaneously. Before 2M there will a mix of Nostalgia and RES.

Please consider coming out to Muncie to help the ESL have yet another strong showing on this National stage. Then, after the NATS, will be the US F3J Team Selection which definitely has my attention!

Looking forward to flying with you all
LET’S GO ESL!
Josh!


2011 CONTEST SCHEDULE
http://www.flyesl.org/calendar.asp

The ESL calendar can be found at the link above and that is the most current information.

For 2011 we have 9 TD and 8 HL contest weekends scheduled. Also note that TD and HL contest dates no longer interfere with each other on the calendar so there can be a TD and a HL contest scheduled on the same weekend.

The ESL contest season runs from April to the first weekend in November, so there are now openings for 32 TD and 32 HL contest weekends each ESL season. If you know a club who would be interested in hosting an ESL contest weekend you can direct them to this link for a little more information. http://www.flyesl.org/News-y-Articles/featured_article.asp?FORUM_ID=7&TOPIC_ID=410

ESL TD SEASON OPENER HRSF/BRASS - May 14 and 15
By Josh Glaab

The Hampton Roads Silent Flyers/Blue-Ridge Area Soaring Society ESL 2011 unlimited season opener is coming up in just under two months. The location is Frankie Coyner field, in Ladd VA. This is located about 1.5 hours west of Richmond, VA, on I-64.

This location is a great place to soar. The field is large and kept in very good condition and the rolling Blue Ridge Mountains make for beautiful scenery. There are several hotels and restaurants within 2 miles of the contest site making it very convenient to fly and then get back to the hotel and out to dinner for some Apres’ Soaring festivities.

This year the plan is to hold another top-quality Unlimited R/C Soaring competition, building upon the success of last-year’s event, featuring a hybrid MOM/Seeded-MOM format. The plan is to have randomized MOM in the morning, before lunch, with Seeded MOM after lunch. This provides an opportunity for many to fly with/against each other but still provide the high-power finish of the Seeded-MOM format.

There are plenty of opportunities for sightseeing with the entire family. The Blue Ridge Parkway and Skyline Drive are just minutes away and offer hundreds of miles of breathtaking scenery for car tours and hiking opportunities.

In Staunton there is the Frontier Culture Museum and the Woodrow Wilson Presidential Library.

In Charlottesville, approximately 30 minutes away, you will find the estate of Thomas Jefferson, Monticello. If you have not seen Monticello, it is well worth taking a day to visit this piece of American history. You and your family will simply be amazed and impressed by the tour.

A half mile away from Monticello is Michie Tavern. This tavern is over 200 years old and is a look into the past. Again, well worth the tour. Usually folks can see Monticello and Michie Tavern in the same day if they arrive early to Monticello and then go to Michie Tavern

RCSOARING DIGEST -

The newest issue of RC Soaring Digest is now available for downloading from the RCSD web site. http://www.rcsoaringdigest.com/highlights.html


WHAT IS AN ESL CONTEST?
An historical prospective By Josh Glaab

The Eastern Soaring League was created in 1978 with an objective to "Enhance the sport of radio controlled (R/C) thermal soaring through the establishment and maintenance of reasonable standards for contest operations". Since 1978 the ESL has evolved, but still reflects the heritage from its' inception.

In 1978, R/C soaring competitions were just starting to gain some momentum. Various capable sailplanes were becoming available that could soar and there was significant interest in competition. R/C Soaring enthusiasts were investing time and resources to attend competitions and beginning to have a great time meeting and flying with pilots from a fairly large region (NY, NJ, CT, PA, MA, MD, and VA). While some R/C Soaring events were well equipped, run, and attended, some events were having issues for various reasons. In response, the ESL was created to ensure a consistently good R/C soaring competition experience. Decisions regarding the format and rules for ESL contests are generally based on one simple philosophy: show up and fly!

To provide some perspective, in the mid-to-late 1970s, high-starts were still widely used. Although winches were starting to gain popularity at soaring sites, sailplanes were primarily designed to be launched from high-starts. While winches were definitely different than high-starts in terms of launching power, there was also wide variability between different winch designs. Some winches were 12 volt, some were 6, some had thick drums, some thin. Some could be operated at either voltage depending on which foot petal button was intentionally, or unintentionally, stepped on. As a result, one significant issue facing competitors was what type of launching equipment would be available at the contest. This was particularly critical for new sailplanes being designed at that time. For example, high-end sailplanes, such as the Legion Air around 1978, were showing-up but they could not effectively be launched from a high-start in many wind conditions.

In addition to the launch equipment issue, there was also wide variability regarding what could be considered a desirable R/C Soaring competition format. Contest Directors (CDs) seemed compelled to experiment with flight tasks and landing tasks, sometimes just in an effort to stand out. Some of these experiments were beneficial and had lasting positive impacts, some of them really did not stand the test of time. While it is still listed in the AMA rulebook, one example of a reviled soaring task that did not stand the test of time is called Triathlon. The triathlon flight task would award more flight points for even-minute flights than odd-minute flights. For example, a 6 minute flight time would earn a higher score than a 7 minute flight time in a 10 minute task.

Pilots had to determine if they could get from one scoring peak to the next. The creators of Triathlon felt that this would be intriguing and interesting to the competition pilots. However, the level of thinking and strategy involved with Triathlon during a short-flight was a problem and many vehemently hated that contest format resulting in it rarely ever being used. Other examples of poor choices of flight tasks of well-intentioned yet highly-clueless CDs could include loops and other nonsense that has nothing to do with soaring.

Landing tasks were widely varied as well. Overall, the graduated spot landing of various sizes and gradients has been the most popular and useful task over the years. However, some competition events would again experiment with various strange ideas such as bonus points for hitting the out-house, or landing on beach balls, etc. These landing tasks may be Ok for a local club event where a significant element of luck and need for variety may be desirable, but are definitely not something many would find enjoyable or rewarding.

Combined with the uncertainties of launch equipment and flight and landing tasks, there were additional issues regarding the group running the competition. In many cases, a local group would acquire an AMA sanction, publish the event in the AMA Magazine with the intent of drawing outside participation, and hold a competition but that would be based on monthly club events. In this scenario the contest organizers would not get to the field until 10am, have a 2 hour lunch break, and have a very limited amount of flying. While the contest organizers would acquire an AMA sanction with the intent of having a significant event, they were mostly interested in fun flying and may not understand the level of flying that would be expected of them from those who may travel to the event.

Overall, R/C soaring competitors were interested in attending many competitions each year at the inception of the ESL, but were challenged regarding which contests to invest their time and money to attend given the potentially large variability due to launch equipment, flight and landing tasks, and general contest operation. The creators of the ESL wanted to establish a set of guidelines to ensure that ESL sanctioned events were consistently of very high quality and well-worth the expense of attending. Again, the over-arching philosophy guiding decisions regarding ESL contests was to show-up and fly!

On paper, ESL Thermal Duration events do not appear significantly different than other AMA sanctioned events. Part of this is due to the fact that many of the elements that make ESL events so special are not written down. ESL competitions are required to have an AMA sanction which implies the basic AMA rules are followed. The ESL season runs from April through the first weekend in November but usually finishes in October. The TD region includes MA, CT, RI, NY, NJ, PA, MD, and VA. Thermal duration contests can be scheduled on consecutive weekends. Having ESL contests as two separate contests provides many benefits and facilitates participation. For example, some pilots may only be able to attend Saturday or Sunday. If ESL contests were one two-day event, many pilots would not attend at all if they had a scheduling conflict with Saturday or Sunday. Having two separate contests also provides pilots with two chances earn ESL scores which also boosts interest and numbers of competitors. With two separate days, pilots can expect to fly competitively on both days no matter how bad one flight (or day) may have been. Pilots take the summation of their best 6 contest scores for the year-end ESL score. Pilots can fly in as many ESL contests as they like, again the emphasis is on showing up.

ESL rules require CDs to publish what the flight and landing tasks will be in advance. Publication of the flight and landing tasks allows flyers the chance to potentially pass on a contest if they were calling for looping high-start triathlon with out-house landing tasks. In addition, CDs are required to replace the winch line on the ESL winches if needed. ESL members assist CDs in determining the need to replace the winch lines. After the competition is over, the scores and list of contestants with contact information are be forwarded to the ESL. CDs are also required to pay $2/contestant/day for every contestant to the ESL. These funds go towards maintaining the winches and equipment as well as other services, such as the ESL website. Entrance to the ESL is automatic upon flying any ESL contest.

In addition to TD events, in the early-90s, javelin-style hand-launch was brought into the league. Fortunately for hand-launch, the rules and operations of the ESL were already well established. ESL hand-launch contests had similar characteristics to ESL TD contests and were well organized, well run, and enjoyable to attend. This year, the ESL Hand-Launch Glider (HLG) league is undergoing a major expansion in both the available weekends (no need to schedule around TD events) as well as region (East of the Mississippi vs. VA, MD, NJ, PA, NY, MA, CT, and RI) and generating a significant amount of interest. While HLG contests do not need to worry about launching equipment, the effect of the ESL is still significant on this segment of the soaring society. The ESL provides the organization to ensure that ESL DHLG contests are well organized and run. A series of well-run ESL-HLG competitions generates interest in this R/C soaring segment which in-turn supports the ESL.

At its’ inception, the ESL instituted Expert and Sportsflyer pilot groups. The reasoning for pilot-skill groups (as opposed to aircraft span or limited control function groups) was to encourage new developing pilots to participate in the ESL and improve their skills. There is a points system developed to determine when Sportsflyer pilots need to advance to Expert class along with a highly-developed pilot advancement ritual.

For both TD and HLG divisions, collecting scores and recognizing the top pilot accomplishments adds to the interest in the competitions. Pilots compete at the various ESL events as well as getting to the events. Given the existing scoring system which only counts the top 6 TD competition-days of top 5 HLG competition-days, pilots who can fly in all the ESL events have an advantage over those who can’t attend all of the ESL events. In the TD and HLG divisions the top Experts and Sportsflyers are recognized each year. The most improved pilots are also recognized.

Elements of ESL contests that are not written down are much more numerous. In addition to the ESL rules, one of the positive actions taken by the ESL was to establish a set of ESL winches that are available for all ESL events. These winches have been maintained and continuously updated to a very high level of quality and are available to all ESL contests. Over the years other equipment has been added to the winches to include battery chargers, Walston plane finders to find downed aircraft, 50ft lineman poles to assist in treed aircraft recoveries, spot landing tapes, power cables, etc. Contest organizers need to coordinate the transportation of the winches and equipment to their contest. However, virtually everything required to run the event is available.

The hand launched glider contest have a much lighter equipment requirement since there are no winches, winch batteries, chargers or generator needed to run the contest. In many cases the equipment to run the contest is provided by the local club or contestants attending the event. The ESL does may a PA system available for use by both TD and HLG CDs.

It is becoming much more of the norm than the exception to have ESL members and their families helping run the contest in a significant way. ESL members, who are not part of the local club, transport the equipment (i.e. winches, batteries, chargers, charging cables, landing tapes, PA systems, etc.) to the field, help setup the winches, run the winch lines, and keep score. This not only greatly alleviates the burden on the local club, but also provides consistency from one event to the next. The local club usually is primarily responsible for having the flying field in good shape and providing the awards. Other tasks are shared with visiting ESL members.

ESL contests usually have a relatively early start time with 9:00 am pilot meetings and flights beginning around 9:15am. Flying at ESL contests usually continues until 4pm on Saturdays and 2pm on Sundays to provide competitors time to travel home. Lunch breaks are usually fairly short, if they are taken at all. Generally, ESL contests have approximately 14 rounds over two days. The number of rounds can be affected by weather. But if the weather is good, there is a lot of flying. After-soaring camaraderie is usually the case with many pilots and families getting together for beverages and dinner. These after-soaring events can be an extremely good time and worth the expense of the ESL competition weekend by themselves.

Other elements common to ESL contests are "popoff" provisions. These provisions are included to allow contestants to have a poor launch and popoff without effectively being eliminated from the competition. Usually, Experts are allowed one popoff in the first round each day. Sportsflyers are usually allowed to have a popoff in any round, or multiple popoffs per day. Providing some popoffs reduces the risk that a competition day will be ruined by an unfortunate single event due to an extremely out of trim aircraft or bad throw.

Recently, the ESL has embraced Seeded Man on Man contest formats. This has had the benefit of really increasing the interest in the competition, both from the competitors as well as the helpers and spectators. For the first round, the CD establishes a ranking of the pilots. Most times this is based on current ESL standings. At the end of each round, the scores are calculated and a new ranking of pilots’ is created. The flight groups are set to fly pilots 1 through 4 against each other, then 5 through 8 and so on. Sportsman flyers are typically flown separately when there are enough to form at least one group. The fact that the pilot rankings are used for the flight groups keeps everyone much more engaged regarding who is having a good day. The flight groups are ordered from lowest to highest and this produces the last flight group of the day to determine who wins the contest. Very exciting! There is usually also some amping-up of the crowed by the folks running the contest to highlight this event to produce an electric atmosphere with a dramatic climax.

In summary, the ESL has created written rules and unwritten procedures that taken together provides for a series of amazing R/C soaring events each year. Through these events R/C soaring pilots are able to meet with and fly with others who share the same interest from a fairly large region. Without the ESL, many of these relationships would not be possible. ESL members provide a great deal of help facilitating these competitions and a great time is had by all. If you are new to R/C soaring, or new to the ESL region, it is definitely worth the time to attend an ESL contest and experience the fun R/C soaring can be with the ESL.

SPEKTRUM ANNOUNCES DSMX TECHNOLOGY –
Spektrum adds Frequency Hopping to its Product Line

What does it mean to you?
http://www.spektrumrc.com/DSMX/

You can upgrade many DSM2 transmitters to DSMX for $75. This is taken from the FAQ

Before investing in the DSMX transmitter add-on, there are several important facts about DSMX you need to know:
• To realize the full benefits of DSMX technology you must have both a DSMX Transmitter and a DSMX Receiver
• DSM2 transmitters are compatible with DSMX receivers. Likewise, should you add-on to a DSMX transmitter, the DSM2 receivers you have now will be compatible with it.
• Because DSM2 and DSMX share the same wide-band DSSS foundation, all Spektrum users will enjoy superior range, speed and precision whether they’re using DSM2 equipment, DSMX equipment or a combination of both.
• The difference a DSMX system makes is only apparent when hundreds of 2.4 GHz systems are in use at once.* DSM2 users who rarely, if ever, fly in big events or other exceptionally "noisy" 2.4GHz environments may find the DSM2 equipment they have now is all they will ever need.
