    2011 AGM Committee Proposals

    By Robin Sleight, in BARCS,

    Committee Proposals for changes to BARCS Handbook Rules
    Committee Proposal One
    To create a “Restricted Model” class for Electric Soaring events
    3.3 Model Characteristics
    That a new section 3.3.7 be created with the following text:
    “A restricted electric model must either have a wing span not exceeding 2 metres (with no limitations on the control surfaces or functions) OR alternatively have a wing span not exceeding 100 inches but with control functions (other than the motor control) limited to rudder, elevator and spoiler only.  The control functions for the flying surfaces are thus the same as for a 100s model”. 
    Renumber the existing 3.3.7 and 3.3.8 (dealing with nose radius definition and ballast to become 3.3.8 and 3.3.9 respectively.
    Also change section 4.2.2 (dealing with multi launch rules) to read:
    Electric models shall also lie within the area, weight, wing loading restrictions as defined in the Standard Rules but in addition they may not exceed 4000mm in wingspan for Open Class models, or 2000mm/100 inches as relevant for the restricted model class.
    Also change section 4.2.1 (dealing with the ELG rules) to read:
    The electric models can, if the flyer so elects, be of the restricted model class rather than Open electric. If a restricted electric model is used throughout the event that will count towards a restricted model electric league score as and when such a league is established.
    This change formalises the class which includes 2 metre models but avoids creating yet another sub class. There are numerous redundant 100s models suitable for electric conversion and the performance of an RES model of 100 inch span (including the greater difficulty of achieving a precision landing should be comparable to a multifunction 2 metre model. This change is to encourage greater participation by giving a new lease of life to such 100S models.
    Committee Proposal Two
    To better equalise the launch height gained in Multi-launch events
    That the text of the final two sentences of section 4.2.2 b of the Multi launch Rules be changed to read:
    The height limiter device should be set for cut-off at a height of 150 metres above the launch height or for 30 seconds from “power on”, whichever comes first.  The height limiter switch must be installed in such a way that adequate venting to it occurs such that outside air.
    Experience of Multi launch competitions during 2011 has shown that electric models with the height limiter set at 200 metres are at a significant launch advantage relative to winch launched gliders.  This is especially so in light winds.  Additionally the electric models can use the “power on” phase to penetrate to the most promising section of the sky whereas the winch launched gliders are, by necessity, restricted in where they are positioned when free of the winch line.  This again gives the electric models an especially valuable advantage in windy conditions.  The change will even out the playing field in both light and stronger wind conditions.
    Committee Proposal Three
    Use of Models in Multi launch competitions
    That the text of section 4.3.2 a be changed to read:
    Double entries where, for example, the second entry is of a different model class, will be permitted with the specific agreement of the CD.  The CD will determine whether or not to accept double entries dependant on the total number of entries received. This is to ensure as much flying, with as many rounds as possible, for all competitors in the time available.
    The current text of this section prohibits double entries for “large” events and generally does not encourage them.  Provided the double entries received do not result in a significant loss of the number of rounds which may be flown in any event, such double entries can be valuable in making up the numbers, indeed they may be necessary in order to ensure a viable competition.
    Committee Proposal Four
    To allow an alternative height limiter for electric models
    This is intended as a provisional change to allow the impact of it to be monitored through 2012 and also in recognition that further height limiting devices are confidently expected to be available during the course of 2012.
    That Multi launch section 4.2.12 be amended to add to the list of allowed height limiters is the (USA manufactured) CAMlimiter.  This would be achieved by changing the words January 2010 to January 2012 and inserting after the web address for RC-Electronics the words:
    The “CAM” limiter is also approved for BARCS ELG events”
    ELG Rules section 4.4.1.d.  Incorporate the same changed wording as for 4.2.12 above
    The CAM limiter (which does not have downloading capability) is cheaper and has been widely used in the “Bartletts” series of events without any problems. The nominal lack of “anti zoom” feature of this limiter has not proved to be an issue in practice relative to the RC-Electronics limiters. However this will be monitored during the 2012 season to ensure that flyers are not unfairly exploiting this feature by flying techniques not thought to be in the spirit of the rules.
    A check on the setting of the limiter (as may be required under Rule 4.3) is still possible (by counting the set up bleeps) without downloading and this limiter can be set to 100, 150 or 200 metres thus making it suitable for both multi launch and ELG events.
    Committee Proposal Five
    Dropped scores in ELG events
    That the dropped score in ELG rules 4.4.7a applies only after six or more rounds are flown – not four as at present The text would now read:
    Where more than 5 rounds are flown the lowest score will be discarded.
    Due to the nature of the event, ELG contests proceed quickly and, given reasonable weather, it is not difficult to get five or more rounds completed.  Thus dropping a score after (just) four rounds is not best suited to this type of event.

    2011 BARCS Leagues Year End Report

    By Austin, in BARCS,

    The 2011 BARCS Soaring Season came to an end on October 9th and the final league tables can be found in the appropriate class tabs.
    One again the weather affected many competitions, either resulting in postponement, cancellation or curtailment with just enough rounds flown to make them count. Despite this 90 individual members entered competition, recording 205 class entries. Congratulations to all the winners, you will be being contacted about trophy arrangements in due course.
    On behalf of all the competitors and BARCS we would like to offer a special vote of thanks to all the organisers and CD’s for their hard work and to the clubs who gave access to their fields.
    The All Rounder Tables are too large to be displayed on the website and are available to view or download here

  • Our picks

    • At this time of angst in the Coronavirus Pandemic, many of us are feeling bored and without many opportunities to fly our models, and that means more time on our hands. So here is a chance to catch up Uncle Sydney’ Gossip Columns, running over the years from 1998 through to 2019.

      Before starting let me thank Jojo Grini who has maintained a web diary of all my reports in Norway and sent it round the world. Thanks also the Austin Guerrier who helped me to reach websites in UK and USA and other continents. And other F3J pilots told me that they enjoyed my Gossips.

      To read, type the following address: www.f3x.no/f3j/gossip/index.htm. Be warmed it takes a long time to read it in full.

      Brian Austin has been co-opted by the BARCS Executive Committee as the new President of BARCS. His three year term of office will be confirmed by the membership at the AGM 2019. I am confident that this announcement will be welcomed by all BARCS members. Many, if not all, members know Brian from his long record of achievements and activities in the silent flight field. He is especially known for his friendly cheerful manner, always at hand to help fellow modellers.

      Four years ago, Brian was awarded BARCS’ Eppler Trophy, in my opinion, the association’s the most prestigious award with a long list of distinguished aeromodellers such as Eppler himself.

      Graham James, BARCS President at that time, wrote the following citation: In the early years of BARCS, awarding was often a relatively straightforward decision as new construction methods, materials, wing sections, control methods and launch and landing requirements demanded continuous model development. Today, many of us have moved onto moulded ready builds and the skills of the true modeller are largely being lost.

      One person, Brian Austin, continues to lead the field in home design and build models. Responsible over the years for many familiar Open and 100s designs, his name is now better known in electric circles not only for his planes but also as a driving force behind competition rule progression. Names like Trilogy, Alacrity and more recently the Watts series of electric gliders, of which Watts New is the latest incarnation, will be familiar to us all. For many years, he has also been the responsible for running a very successful series of competitions in Essex.

      Although tempted by shiny plastic models too, he continues to fashion exquisitely beautiful soarers, built to standards that most of us can only
      aspire. They take the latest look and feel of moulded machines, but are built in more traditional ways. Brian pilots competition winning models.

    • Can F3J survive the treatment meant to save it
      What are the new rules?

      Two weeks ago the RC Soaring Technical Meeting in Lausanne took the bull by the horns and introduced new rules aimed at saving F3J glider contests from sliding off the world and continental championship schedules - the death of what for many soaring pilots is the most popular of silent flight competitions.

      Joe Wurts, the first F3J World Champion in 1998 at Upton-upon Severn, UK. Twenty years later with the latest F3J WC about to take place in Romania, many soarers are fearing that this could be the last.


      From next year pilots can use electric winches - either/or hand held winches - for launching their models. The models must have a maximum surface area of 150 dm2 and a minimum loading of at least 20 gm/dm2. There will be no dropped round in fly-offs, and no reflights for mid-air collisions after 60 seconds into the slot.

      CIAM, the world ruling body for this class is hoping that its new rules will halt the massive fall in numbers of F3J pilots wishing to compete, sixty per cent over the past five years and still falling, and restore its popularity.

      But among many F3J pilots, the bull is still shaking its horns. There has been an extraordinary shock reaction: hundreds of pilots from all over the world have reacted on social media, protesting, angry and forecasting the end of this class. Many pilots are concerned, ranging from previous finalists and champions to your typical enthusiast who enjoys travelling across country and continental boundaries to participate in their friendly sport. Only a few can see the logic and reasoning and are prepared to wait and see how the changes work in practice. More than a few want CIAM to think again!

    • Rule changes to halt terminal decline
      Uncle Sydney’ Gossip column returns

      FAI’s Aeromodelling Commission meets next month, 27/28 April 2018 in Lausanne, Switzerland. For F3J pilots the main topic on the agenda is how to halt the decline in silent flight contests. What does CIAM want to change?  What chance for these changes to save terminal decline?

      Winches to be allowed.

      If this proposal goes through the “launch of the model aircraft will be by hand held towline or winch.” Ever since 1998 when the first F3J world championships were held at Upton on Severn, pressure has been on CIAM to bring in winch launching. At numerous team managers’ meetings held by Jury President Bartovsky during World and European championships, arguments for and against have raged. Many countries do not have enough people to give one or two man tows, so they run their qualifying comps to local rules using electric winches. I guess more than half of countries do this. When they turn up at FAI championships, their pulleys and hand winches are brought out. In the UK perhaps we had one or two practice sessions at home before leaving.

      Certainly there is a difference between a regulation F3B winch and a two man tows. The best pilots still gain the most height either way. The big difference is what you need to carry on your travels, especially by airline. Winches and batteries are bulky and heavy. So far all votes have been to stick with hand towing.

      In CIAM agendas, any rule amendment is followed by its reasoning. 

      The winch proposal stems from Slovakia and they say: “The majority of pilots are older persons who are no longer physically capable of towing models. ( Uncle’s note: I have not seen anyone on crutches yet!) .....

      We and the BARCS executive committee wish all members, and indeed everyone who enjoys model flying and thermal soaring, a very happy Christmas, and also a very special year ahead in 2018. May all your achievements, higher scores and hopes be realised.

      Year 2017 has been a mixed year, probably for everybody. The biggest triumph by far has been the successful opening of BMFA’s National Flying Centre at Buckminster. BARCS can be very proud that it was the first group of aeromodellers to utilise the facilities on offer by organising a successful Radioglide 2017 at the end of May. 

      There is still a long way to go until BMFA realises all its ambitious plans for the NFC. Very sensibly, they are taking a careful financial route. Many members will not have even seen the site so far. Don’t hesitate. Many other members are in the band of volunteers, regularly making the Centre bigger and better. Offer to help if you can!

      One of the prime movers to establish the National Flying Centre is Chris Moynihan as chairman of the BMFA and also a member of the BARCS executive committee. Many years ago, it was Chris who tackled the difficult job of persuading BARCS to grow closer to the BMFA. He then went on to become chairman of the BMFA with his dedicated drive and skill at bringing together proponents and opponents. Very sadly, due to health problems, Chris has stepped down from both the BMFA chairman role and the BARCS committee. We shall all miss his wise counselling. 

      All the very best - and plenty of thermals - for 2018!

      Sydney Lenssen, BARCS President
