I flew the Ryan NYP now recovered in Protex for a total of two flights, 4 minuets a flight. All that way I hear you say for 2 flights, well yes, it's not only for the flying. Its too see old and new friends, new models, motors and to get BEFA into the Continental Model Magazines! I was talking to Ludwig Retzbach (scale flyer) about coming over to the Middle Wallop event next year, all I got was a blank look. It seems the European flyers don't get our dates of fly-ins published in their magazines! This has now been rectified with some words and our web address in all the main German / French magazines. I had a few phone calls and emails regarding this year's missing Woburn Abbey event! Sorry folks your committee cannot be in two places at once. It clashed with the World Championships in York, and Woburn Abbey did not have another weekend free, we will try for 2005. Well that all for now, see you at the Technical Workshop KEEP THE WATTS UP and FLY SAFELY! Robert Mahoney F5B / F5D World Championships Thanks The British Electric Flight Association have been asked to pass on thanks to all those that helped with running the F5B / F5D World Championships, in whatever capacity. The World Championships Organisers and Competitors. BEFA Technical Workshop Invite to Electric Flight Traders The British Electric Flight Association extends an invitation to all electric flight traders to attend the Traders Fair at the Technical Workshop. If you are interested in attended please contact the Secretary, Peter Turner, details on opposite page. E.F.-U.K. 5 Current Lines from the Editor You will probably notice that this issue is a little late in arriving. The reason is that I received very little to put into the magazine. If it had not been for the F5B/ F5D World Championships it would not have been worth producing the magazine. IF THE TREND OF DIMINISHING SUBMISSIONS CONTINUES THIS MAY BE THE LAST ELECTRIC FLIGHT - UK MAGAZINE! It takes me numerous hours (more than I dare to admit) to edit the magazine into what you see every quarter. I have a demandig full time job and just do not have the time to write the magazine as well as edit it TO PRODUCE THE MAGAZINE I NEED YOUR HELP! Articles on any subject related to electric flight will be considered, as will photographs of models. Please think carefully if you have anything you can submit for inclusion. Please don’t let me down or the magazine may cease to exist. Regards Jan Bassett 2005 PRESS RELEASE Designaction Ltd announce the dates for the Wings & Wheels Model Spectacular 2005 - Saturday & Sunday 25th & 26th June at North Weald Airfield, Near Epping in Essex (close to junction 7 of the M11 motorway).

If you are a manufacturer or retailer that has something new they want to share with the readers, please send details to the Editor (addresses on page 4). Model Motors have been extremely busy over the past months in completely redesigning the entire AXi range of motors. The new range have been made smaller and lighter, but now include greater efficiency due to a new method of winding. The new AXi motors also offer greater durability due to the integral rear bearing carrier and physical support for the magnets in the rotor. All motors in the new AXi range can be used with the optional radial mount sets. Puffin Models continue to support their direct customers under the usual arrangements (free testing and spares fitted with no labour charges), and are always happy to offer testing and repair services to customers of other dealers under full repayment terms. Puffin Models remain happy to receive requests for Model Motors products from model shops. If you want advice on the entire Model Motors range call John at Puffin on 01454 228 184 during working hours, or see www.puffinmodels.com for the full Model Motors catalogue and independent test results. The latest motors in the range are the new 2826/10 and /12 that have been produced to meet a requirement that Puffin Models had for a small motor to replace engines in the .40 range. They turn propellers of up to 14” x 7” direct drive from a motor weighing only 181g and using Speed 600 mounting holes. Puffin Models continue to the motors from stock, and the 2826 motors are £56.95 8 E.F.-U.K. Above is the LN Models Crazy Impulse, new to the UK and imported by Puffin Models. LN Models kits are produced to a high standard in the Czech Republic by Libor Nezbeda. The Crazy Impulse, in common with most other LN Kits (including the Vermont Belle 1300), is designed to be super light to make the most of lower cost (and lighter) bushless power systems. LN Kits are supplied as ready built components covered in Solarfilm and ready for final assembly. CNC cut vinyl stickers are supplied in the kt. Crazy Impulse is not designed for beginners, but intermediate to advanced flyers will appreciate the responsive nature of the low weight and low inertia airframe. This 55” (139cm) wingspan model can weigh as little as 3 lb. (1360g) when fitted with a 600 size brushless motor such as the Model Motors AXi 2826/10, or Mega 22/30/4, along with the recommended 10 RC-1600 cells (accessed through the ready made top hatch). It is no longer necessary to have expensive motors and batteries to have top notch performance!. The Puffin Models price for the Crazy Impulse is £139.95. Talk to John at Puffin Models on 01454 228 184 about the the Crazy Impulse or other LN Kits. Alternatively click on www.puffinmodels.com to see more on the other LN Models shown below. E.F.-U.K. 9 The Graupner Ultra Duo 30 is produced in Germany and includes a sturdy metal case with rugged buttons that should still be in place after many hours of use. the front of the case says “micro-processor controlled rapid charger, discharger, battery balancer and capacity meter”, which just about sums it up, it does exactly what it says on the box. The charger uses different programmes for NiCd, NiMH, Lead Acid, and Lithium cells. There are both manual and automatic charge modes, and the maximum charge current can be set prior to charging. When in the Lithium programme, the charger requests confirmation of the number of cells before starting the charge, so we should have no incidents as the result of charging at the wrong voltage. Output 1 is for 1-30 NiCd or NiMH cells, or 1-10 Lithium cells with a charge rate of up to 7A and a discharge rate of up to 5A. Output 2 is for 4-8 NiCd or NiMH cells at up to 500mA, a useful addition for field charging of radio batteries. On the front of the case it also says “read instruction manual!” which is well worth doing as it not only explains the operation of all the features in the charger in simple terms, it is also full of useful tips about the storage and charging of different cell types - yes, the instructions and menu are in English! Did we mention the 24 month warranty? The Puffin Direct price for the Graupner Ultra Duo 30 is £137.95. Call John at Puffin Models on 01454 228 184, for more information about this experiences of using the Graupner Ultra Duo 30 or other Graupner electric flight products, alternatively visit the Graupner on-line catalogue through www.puffinmodels.com 10 E.F.-U.K. Mega design and make their own high quality brushed and brushless motors. The Mega Mig motors are low cost motors with similar fitting sizes to other can motors, and they perform every bit as well, if not better than, other can motors. All the motors except the 400 6v are supplied with a flux ring to increase the torque and efficiency of the motors. Mega Mig motors have very effective internal suppression to meet EC requirements. Puffin Models are flying a RCM-Pelikan Swift thermal soarer with the Mega Mig 600 8,4v on 8 RC-1600 cells with a Graupner 8”x5” propeller assembly, and the climb performance is very good to say the least! The Puffin Direct prices for the Mega Mig motors range from £3.95 for the 400 6v and 7,2v to £6.95 for the 600 7,2v and 8,4v. Mega Motor also have an excellent reputation for their 400 size 16/15 series brushless motors, perhaps a little less well known are the larger 22 series motors. The 22/ 20/3E is the very latest 22 series motors and is the same size as a normal 500 type motor. The rotor on all the Mega motors contains a series of magnets making them multi-pole motors with high torque characteristics. The 22/20/3E has a 12 pole (magnet) rotor making it most suitable for direct drive use. The Kevlar binding of the rotor also means it can be used at high speed (on higher voltages) with gear reduction. Typical uses for the 22/20/3E are 8 cell sports aerobatic models with propellers of 9” x 6” to 10” x 6”, though the 22/20/3E can be used direct drive with up to 10 cells. What do the numbers mean? 22 is the diameter of the rotor, 20 is the length of the rotor, and 3 is the wind of the motor. E is the designation for “Energy Star”, motors that draw less current for a given propeller and cell count. Mega motors are made in the Czech Republic. The Puffin Direct price for the Mega 22/20/3E is £58.95 - fantastic value for a 500 size brushless motor that is made in Europe If you want to know more about Mega motors, or the huge range of Mega motors stocked by Puffin, call John at Puffin Models on 01454 228 184, or click on www.puffinmodels.com. Puffin Models welcome enquires from model shops about Mega Motor products. E.F.-U.K. 11 The brand new production F35-C Joint Strike Fighter has just arrived! At least it has in the form of the brand new Electric Ducted Fan kit from Rob Bulk of RBC Kits in the Netherlands. As with all of the RBC kits, the F35-C is a real builders kit with detailed construction plan, vacuum formed parts, and selected CNC cut balsa parts. In common with other serious EDF models, the F35-C should be bungee launched (ideally from a ramp set at 15 degrees). The F35-C is typical for a Mini Fan 480 powered model at 700mm wingspan. As an EDF specialist, Puffm Models stock all of the specialist items required to complete the model including micro servos and motors suitable for use with the WeMoTec Mini Fan 480 using anything from 8 sub-C cells right through to 4s Lithium cells. Puffin direct price for the RBC F35-C is £76.95, or £101.95 with the recommended WeMoTec Mini Fan 480. Phone John at Puffin Models on 01454 228 184 for more information about RBC kits or serious EDF systems in general, or visit www.puffinmodels.com to see the RBC Kits website. 12 E.F.-U.K. Model Motors have established themselves as a pioneer of cost effective outrunner brushless motors. These motors offer slower rotational speeds, in conjunction with good torque ratings, allowing larger propellers to be used direct drive. Model Motors also supply a lot of other items including a range of planetary and “Intro-gear” type gearboxes, which can be useful with other makes of motor. There is also a range of small conventional brushless motors as well as ferrite and Neodym motors aimed at the popular 6 to 8 NiCd or NiHM cell applications. All these products are well presented and illustrated, with technical data, in their first (12 page) English A4 full colour brochure. The catalogues are available unfolded in exchange for an A4 stamped addressed envelope from Alan Fry at ImporTekniK, 29 Braiswick, Colchester, Essex, CO4 5AU (Tel 01206 852 209). E.F.-U.K. 13 Above is the Lea V, which is the F5B model that was used by the French team during the competition. It has a span of 1775 mm and is designed for anything between 7 and 24 cells. It is available in 4 options: Standard £410, Standard with wing servos £510, Carbon D-box £442 or Carbon D-box with wing servos £560. Below is the Venesa, a model design specifically for the 7-cell competition with a 1500 mm wing span. It is reputed to be a competition machine that flies like a dream in the hands of a sport flyer. The Vanesa is priced at £280. Both are available in the UK from Phil Dorren at Spot On Models, see page 59 for contact info. 14 E.F.-U.K. GWS Propeller Repair Hub by Malcolm Mackendrick (illustrated by Jan Bassett) It is quite easy to break a GWS propellerm and it normally leaves one blade intact. This little gadget can be made to recycle 2 such broken propellers to produce a good one. The hub is turned from Nylon or other similar material; it is not too critical due to the slow speed of these GWS propellers. The larger through slot can be milled or carefully made with a saw and files. The smaller slot is cut with a razor saw, which will be used to cut the propeller later on. The ciritcal dimension is the larger hole in the centre, which needs to be a close fit on the propeller boss. Unfortunately each size of GWS propeller has different boss dimensions so a hub will only work for one size of propeller. Each broken propeller is slotted into the hub with the good blade against one side of the blade slot. Using the razor, saw the propeller boss in two. Once the saw nears the bottom of the slot in the repair hub, the propeller is removed and the cut is continued. The two half propellers are inserted in to the hub with the front of the blade to the bottom of the hub. This allows the nut on the back of the shaft to fit into the heagonal hole in the propeller boss. Please send any questions to the Editor, see page 4. E.F.-U.K. 15 Readers’ Models Your chance to show the members your model(s). Above is Mike Moore with his Lanzo Bomber. This old timer model was built from a Leisure kit he bought quite a few years ago at a BEFA Technical Workshop . Mike says that the kit was the worst set of parts he’d ever come across and meant that he had to re-cut most of the wing ribs and much else besides! It was also quite difficult to achieve an accepatbly forward enough C of G with the long tail moment, despite keeping the tail end as light as possible. However, the end result was well worth the effort. It is a real joy to fly and my club mate, Angi Piacentini, told me the interesting story that the designer, Chester Lanzo, won many free-flight contests with it and that its success was largely down to the leading edge stringers providing a turbulator effect. It certainly is a floater and incredibly stable in flight. The Bomber has an AXI 2808/16 brushless outrunner fitted with an AC2512-3 ESC from Puffin, an 8 cell pack of 2100mAh 4/5 AA cells and 10” x 8” CAM propeller. The Rx is a Multiplex Pico 4/5, covered in Profilm and all-up weight, ready to fly, is 1 kg (2¼ lbs). 16 E.F.-U.K. The four photographs on these pages are of Chris Golds’ latest model, a Canberra B(I)8 from the late 1960s. It is built from balsa and liteply and covered in tissue E.F.-U.K. 17 and dope. The wing span and length are identical at 84” (2.1m). The flying weight is 17 lbs (7.7 kg), giving a wing loading of 23½ oz./sq.ft. (71.7 g/dm2). The power is provided by 2 Hacker B50-16L brushless motors fitted to the 90mm (3½”) WeMoTec Midi-fans. It has 2 x 20 cell battery packs of 3300 mAh NiMH cells. The models features Retracts, Flaps, Doors, external 1000 lb bomb (which are fixed) and tip tanks. To quote Chris it “Flies great, loadsa poke!”. Chris also says that it will be a plan in Flying Scale Models. 18 E.F.-U.K. Lightweight Scale Wheels by John Ransom To build a new scale model you start with the wheel, is that right? Well that’s what I try to do. I failed to do this on the latest Mosquito and I am not satisfied with the results. In dreaming about that new scratch built plane to be built for the winter, it has to have the right wing loading and the appropriately sized lightweight wheel. As models seem to be getting bigger and bigger now, the 100” (2.5m) wingspan is quite common to some, and positively small to others. However, the wheel size required for this size of model is often around the 5 to 6 inch (127 – 152mm) diameter, and the choice then becomes very limited. With any model, additional weight is only dead payload, and with electric models it is even more of a concern. Add to that the fact that the retract actuators, whether air or servo powered, have to haul up the additional load of the heavy wheels, then it makes sense to get a wheel that looks scale and is as light as Flair wheel 5” diameter, the lightweight standard for many years. E.F.-U.K. 19 Dave Brown 6” diameter foam wheel. Too narrow for scale. possible. Some of the scale 5 inch (127mm) and 6 inch (152mm) wheels sold nowadays are very heavy and simply not suitable for electric models or retracts. Over the years I have been using the Flair (Punctillo) smooth hub wheels, which are made up to 5” (127mm) diameter. These are scale like in appearance and they are not heavy at all. At 2¾ oz. (78g) for a 5” (127mm) wheel they have been our standard for a few years. Also made in this range are 4” (100mm) and 4 ½” (115mm) diameter and they are used by many scale modellers. Brian Taylor also supplies them, and if they are OK for him, then they are OK for me. However, the Flair wheel is not made in the 5 ½” (140mm) or 6” (152mm) diameters, and after that we have been stuck at finding an equivalent weight wheel made by another company. I have been searching everywhere for lightweight wheels and I thought I had found the answer. David Chinery kindly put me on to Dave Brown Products in Ohio USA who make ‘Big Lite’ wheels, and I duly sent away to Tower Hobbies at www.towerhobbies.com. Within a few days, hey presto, the 6” wheels were posted through my letterbox. The weight of these foam wheels is fine at 3 1/8 oz (89g) but they are too narrow (1 ½”) to look like scale wheels, so it was back to the drawing board. 20 E.F.-U.K. I had also previously bought some 5½” (140mm) Stuart Mackay wheels from Stuart, and these look good. They are still light compared to other wheels, but even these weigh in at 7 ozs. (205g) each. These are fine for the heavier petrol or glow models, but marginal for electric models. In visiting the Dortmund Modellbau exhibition this year I noticed that Kavan now make 125mm (~5”) and 150mm (~6”) Superlight Scale Air Wheels. These are inflatable and the 150mm wheel only weighs 95g (3.5oz)! At last a true lightweight scale wheel. Kavan advised that these can be obtained by SMC models (on 01903 207525) and they duly got me some. They are great, well done Kavan. They also do the smaller sizes but unfortunately not the 5 ½” size yet, let’s hope they tool up to make these one day. If you would like some more details the wheels can be found in their catalogue on www.kavanrc.com - Accessories - page 16. You will probably notice that Kavan also do a smooth lightweight balloon type scale wheel at 100mm and 125mm which would look good on the vintage plane type. S Mackay 5 ½” diameter wheel, a bit heavy for electric models E.F.-U.K. 21 Kavan 6” diameter wheel. These wheels can even be fitted with chrome plated wheels covers or even electromagnetic brakes as an optional extras. The wheels can be ordered with ball bearings if required which add 5g to each wheel. The tyres are inflated up to 14psi with a bicycle pump. If required, the two -piece wheel hub can be used to hide the wheel collar inside. They really have thought of everything haven’t they? The table below shows my efforts so far to source the best lightweight scale wheel, and to my mind at 5” and 6” the Kavan wheel is the best, unless you know better……… Have you found any others that compare favourably? If so please let me know on [email protected] 22 E.F.-U.K. Kavan superlight 6” diameter wheel weighs in at only 95g E.F.-U.K. 23 Kavan removable hub allows collets to be fitted inside if necessary. A Kavan Wheel Electro-Magnetic Brake Unit 24 E.F.-U.K. F5B/F5D World Championships 7 to 15 August 2004, York by Jan Bassett You will almost certainly be aware, from the previous coverage in EF-UK, of the F5B and F5D Open and World Championship competitions that took place at the York Racecourse (The Knavesmire) between 7 and 15 August 2004. Your Editor of EF-UK was also the Editor for the newsletters for these events. It was certainly a very different task to editing this magazine as the information was not available until late evening (or early morning). The information then needed to be converted by the publishing program, reformatted and then entered in the newsletter. Finally I had to print 100 copies for distribution. This was my first attendance at an F5B or F5D event let alone a World Championships. To say I was thrown in at the deep end is an understatement. Fortunately the Open Competitions, from 6 to 9 August, helped me to learn about the different events. The Open Competitions also included the 7 cell and F5F classes, which were not part of the World Championships. For those not familiar with the different competitions, the following is a synopsis for the design limitations and other pertinent information: Common Limits Maximum Total Area Loading 150 dm² 12 to 75 g/dm² F5B Minimum Weight 2000 g Maximum Battery Wgt 1100 g Maximum No of cells 30 F5D Maximum Battery Wgt 425 g Maximum Total Weight 1250 g F5F (as for F5B except) Minimum Weight 1500 g Minimum Total Area 36 dm² Maximum No of cells 10 7 cell - as for F5F except the maximum No of cells is 7. E.F.-U.K. 25 For the Open Competition the F5B, F5F and 7-cell (referred to as F5B for ease) was run as a single competition as the tasks are the same. F5B flights are split into 2 phases; a distance task and a duration task. The distance task is a 200 second slot, where the pilot completed as many legs of a 150m course as possible. As this is a soaring task, legs only score (10 points per leg) if the motor is off. At the end of the distance task starts a 10 minute soaring slot. Each second of flight during the duration task scores 1 point, with 1 point being deducted for each second over 10 minutes and for each whole second of motor run. The flight is completed by stopping the model as close to the centre of the landing circle as possible, and a bonus is awarded of between 0 and 30 points. The pilots of the F5D class must complete 10 laps of a 400m course as quickly as possible. The 3 pylons are arranged in a shallow triangle with 2 sides 180m long and the 3rd 40m long. The pilots score is his time in seconds (to 1/100s), with 10% of the time added if he cut a pylon during the race. If a pilot cuts 2 or more pylons, or does not finish, the race he is awarded a penalty score of 300 seconds. The Open Competitions commenced on Saturday 7 August 2004 and ran until lunchtime on Monday 9 August 2004. Due to the variable weather, only 2 rounds of F5B and 3 rounds of F5D were held. Despite being flown together, the scores for F5B, F5F and 7-cell were calculated separately. 7-cell Open Results F5F Open Results 26 E.F.-U.K. F5B Open Results E.F.-U.K. 27 F5D Open Results 28 E.F.-U.K. A good launch for one of the F5B competitors.

E.F.-U.K. 29 This is the F5B model of Richard Soloman (Australia) captured moments before landing. Another good launch, this time for Johannes Starzinger (Austria). 30 E.F.-U.K. The opening ceremony for the 10th World Championships for electric powered pylon racers and gliders took place at the Knavesmire Racecourse, York, England on 9th August. Precisely at 4 pm the Lord Mayor of York's official car drew up at the marquee where the ceremony was taking place due to the severe storm that was raging outside. Inside 17 teams from as far away as Japan, Australia, USA and Canada were drawn up behind their team managers. After the FAI Anthem and the National Anthem of the United Kingdom, Nick Neve, BMFA's Alternate FAI Delegate, welcomed everybody to the Championship on behalf of the organisers. He was particularly grateful to Sabine Konrath of Germany for the role she was playing as the director of the pylon racing Championship and Stewart Pierce from Canada for his as announcer. Mrs Janet Looker, Lord Mayor of York, welcomed everybody on behalf of the City of York. She reminded us that York was used to overseas visitors. Turning towards the Italian team, she said that around AD 60, the Romans had arrived and called the settlement Ebor. Later about 300 AD, and turning first towards the Danish and then the Swedish teams she said the Vikings had arrived and renamed the place Yorvik, from which the present day name York had been derived. She was then introduced to each team in turn and their helpers chatting to many and wishing each pilot good luck individually. Finally she was shown a pylon racer and a glider and the pilots described their models in detail. She departed with a stainless steel Championship souvenir cut in York by a water jet process. E.F.-U.K. 31 With the Union Flag and the FAI flag flying high from the top of the racecourse grandstand and the rain still falling, the Championships were open. Following the Opening Ceremony, Robin Gowler (BMFA Chairman) awarded the prizes for the Open Competitions. 32 E.F.-U.K. The Ebor stand with the FAI Flag and Union Jack flying over th Championships. The World Championships start The 4th day of the event was the 1st day of the World Championship competitions. The day started with moderately heavy rain. Not an auspicious start! The forecast was that it might clear later in the day, so it was decided to review things at 12.30pm. The decision was that the F5D competition would commence in the rain. The heats were started and they managed to complete 2 rounds. After the 1st heat in the 3rd round, the round was stopped as various problems were starting to develop due to the wet conditions. I think this was a very sensible decision, although the rain stopped almost immediately the decision was made you just can’t win can you. It takes a lot of skill and real dedication to fly in such poor weather and visibility, especially when you consider the models are flying at around 160 mph. As you might expect rain is also not good for cameras so no photographs were taken. A special mention, and thanks from the organisers, goes to all the helpers around the field. These hardy souls stood (or sat) out in the rain for several hours to allow the pilots to fly. Day 2 of the World Championship dawned misty but dry. The initial round of F5B commenced in the mist and low cloud. One model was lost into the cloud and flew away. At the moment it is not known where it landed. During the morning the conditions improved and the round was finished in bright sunshine. On completion E.F.-U.K. 33 of the initial round of the F5B Competition, three rounds of F5D. It was then decided that it would not be possible to fly another round of F5B as it would be too dark at the end. Because of this another round of F5D was flown. Due to the low angle of the sun, it became impossible to see dark coloured models against the tree line. Due to this a small number of reflights were not completed and will be flown on the next day. Not so much the Kanvesmire as a Quagmire! The 3rd competition day dawned murky and wet with light rain. This persisted for most of the morning, but it was decided to start the 2nd round of F5B at noon. The conditions didn’t look promising at noon, but the competition commenced. The conditions steadily improved and the sun was even seen for prolonged periods. The 2nd round was finished without difficulty. Almost immediately on completing the 2nd round, the 3rd round was started. During the 3rd round some low cloud started to pass over the field, which initially caused no problem. Later on the model of Guntmar Rüb passed through some cloud during one climb on the distance task. It was then decided that the remaining flights would not be flown until the following morning. Thanks must again go to the helpers who spent up to 8 hours on the field in their various roles. 34 E.F.-U.K. An F5D model just having rounded pylon 3. The Belgian model gets away, with the other 2 to follow shortly. E.F.-U.K. 35 Photographing F5D models is an interesting challenge - small models flying at extreme speeds and not going in a straight line for long (and then they are side on). Typically a 400m lap is flown in under 7 seconds, which is a mile in under 28 seconds. 36 E.F.-U.K. The launch of Gen Katayama’s F5B model (Japan). Sargey Anashin’s F5B model (Russia) on final approach. E.F.-U.K. 37 Sargey Anashin’s F5B model (Russia) just before touchdown. John Barnes only came look, but spent most of his time as base ‘B’ judge. 38 E.F.-U.K. Ray Pike (Australia) returning to the pits after landing his F5B model. Friday the 13th of August dawned misty and a little wet, although it didn’t delay proceedings much. E.F.-U.K. 39 The day started with a round of F5D being flown to allow the cloudbase to lift enough. As the wind has changed direction, the models were launched away from the start line, which allowed them to pick up more speed before crossing the start. This meant that the 1st lap was faster than in the previous rounds. Because of the longer flight time some models suffered at the end with reducing power, with some failing to complete the 10 laps. Next followed the completion of round 3 of F5B, which could not be completed yesterday. This was interrupted by a short shower, but this only caused a slight delay to the programme. Due to the overcast conditions some longer motor run times were required by some pilots. Once completed the field was handed back to F5D, which allowed the F5B scorers time to compute the results for the round and calculate a revised flying order for the 4th round. Having helped with the scoring they must be praised for their excellent work. The 8th round of F5B was completed in pretty short order and without problems. Again the Easterly wind gave some faster times although slightly slower than the previous round. This was followed at 4pm by the 4th round of F5B, which was flown in improved conditions. Due to the fair weather this round was completed at around 8pm. On the final day it was possible to fly another round of F5B and F5D, making a total of 5 rounds of F5B and 9 rounds of F5D. The final scores are shown overleaf. A late entry for the F5D competition was made by Lachlan Hines (Australia), and is shown here during processing in the main marquee. 40 E.F.-U.K. E.F.-U.K. 41 42 E.F.-U.K. E.F.-U.K. 43 I think it would help to provide further explanation of the markings on the F5 individual scores. The top row in each box is the Round No and then Heat No. Where it is underlined the score has been dropped from the total. The * indicates that the pilot cut inside one or more pylons. The bottom row is the time in seconds to complete the 10 laps. If a cut is made 10% is added to the actual time and the penalised time is shown. If 2 or more cuts are made the pilot us disqualified and 300 seconds is scored. Failing to finish also results in a 300 score. 44 E.F.-U.K. Marcus Moeckli (Switzerland) 3rd place Wolf Fickenscher (Germany) F5B World Champion Guntmar Rüb (Germany) 2nd place Italy Germany Switzerland E.F.-U.K. 45 46 Marcus Wanner (Germany) 3rd place Jens Bartels (Germany) F5D World Champion Dirk Belting (Germany) 2nd place Austria Germany USA E.F.-U.K. The wing was removed, then take cover as another cell explodes To get the maximum performance out of the, typically GP 3300mAh NiMH, cells the competitors keep charging them until they get hot. It is quite normal for them to charge at 12A and not to stop until the pack reaches a measured temperature of 70°C+. However, if the cells are too hot they can go into thermal runaway which will cause them to explode. The Italian team pushed their cells up to 85°C to get that little extra. Unfortunately on two occasions a cell in the pack reached the critical temperature. The first indication is a hissing sounds as the cell vents. The first time it happened the team were at the ready line just about to fly. They heard the hissing and hastily removed the wing of the model and dumped the pack on the floor. The pack sat there hissing for a while and then boom, a cell exploded. This threw part of the pack about 2m and prompted covering the pack with a dustbin to prevent anyone getting injured. The second time was in flight with Remo Frattini part way through the distance task. There was a fairly loud boom and the model suddenly pitched nose up into an uncommanded loop. Remo had no control of the elevator and the model continued to perform another 1¾ loops followed by a vertical descent straight into the ground. It turns out that a cell exploded. This caused the pack to split as seen on the previous pack. Unfortunately part of the pack went backwards and took out the elevator servo giving full up elevator. Most likely as the model slowed on the 3rd loop, the weight of the pack made it move forwards and aerodynamic forces moved the elevator to neutral - thump. The photograph below shows the carnage after two more cells explode some time after the wing had been removed. You just make out a perforated metal sheet on the ground to the front left of the fuselage - it is part of the innards of a cell.

Below: Dave Chinery takes a break from F5D pylon judge duties whilst F5B is flown. A number of traders attended the World Championships at some point during the ten days. Above is the Traplet Publications trailer, which arrived for the second weekend. Phil Dorren (Spot On Models - right below) was present for the whole ten days. Fibretech had been at the show for the first seven days but had to leave on the Thursday for another commitment. Puffin Models (left below) and FVK Modell (centre below) both turned up for the final weekend. 52 E.F.-U.K. The final formal event of all World Championship competitions is the banquet on the last evening. At the 2004 World Championships the banquest was held in one of the function rooms of the racecourse. The above picture shows everyone gathered on the grass enjoying a pre-meal drink in the evening sunshine. Below, the banquet in progress and everyone enjoying themselves. E.F.-U.K. 53 The Event Director, Bob Smith, gave the initial speech before asking Robin Gowler, BMFA Chairman to address eneryone. These speeches were followed by the presentation of two new trophies for the F5B and F5D classes. The F5B trophy was provided by John Emms of Puffin Models, and he is shown presenting the trophy to Emil Giezendanner (the FAI Jury Chairman) for adoption by the FAI. 54 E.F.-U.K. Johns Emms of Puffin Models then presented the F5B World Championship trophy to Wolf Fickenscher, the 2004 World Champion. The trophy for the F5D competition was provided by the members of the BEFA and other electric flyers in the UK. This was presented to Emil Giezendanner for adoption and then to Jens Bartels, the 2004 World Champion. E.F.-U.K. 55 Mike Proctor (Event Manager / Treasurer) (left) about to present a consolation prize to Remo Frattini to assist with any future exploding battery packs. The World Championship sign was moved to the banquet hall so that all competitors, helpers and organisers could authograph it for posperity. 56 E.F.-U.K. Ode to the World Champs anonymous The skies turned to black The rain it did fall The grass turned to a dark shade of mud A Yorkshire man said, “E, It’s turned out grand” A German replied. “Dis not gud” The Pilots despaired Whether they’d get to fly. As the rain battered each, friend or foe. “Will the Sun ever shine?” A Frenchman declared He was answered. “In a minute or so” With the weather at stake We ate fish and chips And we wandered the streets of York City And we watched as the river rose over its bank And swamped our best Pub. What a pity. When the grey turned to Sun We returned to the fun And we flew when our names they did call We strived for each lap as the time ticked away And just hoped the dam plane didn’t stall We’ve had good flights and bad. And mid airs as well, And clouds that swallowed up planes. With records near broke to the sound of our cheers And a museum that’s filled up wi’ trains So that’s how it’s been At the Worlds ‘ere at York. We’ve had hopes with allies and axis But the worst foe we know is the ground down below Terra firma and Impactus Vulgaris E.F.-U.K. 57 PANDAS Fly-In (Pontefract And District Aeromodellers) 18 July 2004, Pontefract Park by John Thompson, PRO BMFA Northern Area This was the second annual electric fly-in, and was favoured by good weather compared to the rest of the ‘summer’. There was an excellent turn-out of 26 fliers, with most having several models. This made it the most successful event ever staged at Pontefract, which must have a message for the future of aeromodelling. There was also the most varied selection of models ever seen flying there, ranging from a B-36 bomber to an ornithopter, with ducted fans and helicopters as well. Unfortunately I was too busy runnig the event to take any notes, and must thank Fred Keegan for taking the photographs, they tell there own story. Simon Cocker kindly stepped in with the loan of his scanner when ours had battery trouble, thanks mate. Many thanks also to the traders, who dontated items for the raffle to swell the coffers, Stephen Mettam was one and he only came to fly. Next year we will have to organise the help better, but at least we had signposts this time. See you then. PANDAS Committee member Tony Waite and his Watt Four 58 E.F.-U.K. Super Mustang EDF Bandit with ornithopter in the background, both flew.

E.F.-U.K. 63 Operation Russian Dolls by Dave Chinery Task - To fly G-AVSI to Middle Wallop (MW), for the Fly-In on 4 July 2004, with mini-G-AVSI on board, then fly that. Operation succesfully completed. Flight to MW had low cloud base in places, but I could see the field from east of Andover. No ATC or other problems at MW. Flew the model three times at MW, then made it back to White Waltham with a really enjoyable flight about an hour before a really nasty Cb loomed. Picture shows the model on the wing of the full-size G-AVSI, with Chris' plastic model on its wing! Thanks again for the loan Chris - I will let you have it back no later than the meeting on the 13th. Still no headsets! Thanks to Robert and Gordon for ground support at MW.

It will flown to the normal E400 league rules. Note: these rounds will not count to the BEFA E400 league results and awards will be presented on the day.
