NO SHADOW OF A DOUBT WHO THE WINNER IS! IT WAS TOO WINDY TO FLY ON THE 16TH FEB. NIC WAS KIND ENOUGH TO ALLOW THE COMP TO TAKE PLACE ON 1 MARCH Michael Borcherds’ winning Angel’s Shadow.
2020 is here, and the first Aerobatic League of the new season for the MAASA Western Cape members took place on Sunday 1 March. Only seven entries in the Masters class took to the air, flying the new P21 schedule. The weather was perfect, after a week of strong SE wind, and this was welcomed by everyone. For flight 1, Stuart was first up, flying his Epic in competition for the first time. Saturday was a bad day, with the loss of complete signal and destroying his Astral whilst practicing at HRF. With only about six flights and many more hours of trimming needed, he managed a good score to take second place behind Michael Borcherds, who put in a strong and very smooth flight. Ernie Smith and Rodney Potter also flew a good flights, while Ozzie Parenzee was his normal chatter box. Pieter Kapp and Charlie Blakemore found the new schedule a challenge. Flight two was once again won by Michael, Rodney improved to end seconds, Ernie dropped a zero on one manoeuvre which put him just behind Rodney and in front of Pieter, Stuart, Ozzie and Charlie.

For the third round, Michael decided not to take part which left the door open for Rodney, but the plane’s wheels dug into the grass runway surface on take-off, breaking the prop... zero score. So now, that left the door open for Ernie; if he pulled out all the stops, he could take the class win. He did improve but not enough. Don't ask him about the landing! It would be a huge call for Stuart to improve so much to win the class. He did improve on his first flight score but not good enough. Pieter improved and was very consistent with all three flights, as was Charlie. Ozzie aborted due to Rx battery failure as he switched the plane on...next time, charge your battery at home before the event; he was very lucky.
Judges enjoying the last rays of summer sun!
To conclude, despite such a small entry, the Notaumatic scoring system worked well, although there were some finger issues from the judges. Thanks to Nic for the use of the Stellenbosh Model Arcraft Academy field, and our judges, Martin Knoetzen, Kas Hamman, and Bernus van der Weshuizen. The next League comp is planned to take place at Tygerberg MFC; hopefully we can get a bigger entry.

Covid and the turning wheel of time. Joe Coetzer
This China virus thing has disrupted many lives, destroyed businesses and yes, a few people died too. None of my family or close friends, which leaves one wondering about the harsh lockdown! I have been building and flying model aircraft for many years. Started when I was five years old, with basic balsa wood and cellulose glue, which came in a small glass bottle with a cork stopper. To get the glue out, a thin piece of balsa wood was dipped into the golden amber liquid and a drop of glue applied to the joint you were working on. The smell of this ancient modeling glue is ingrained in my system to this day. I love it. Rudimentary kits at the time were basically a block of balsa, with sheet wings and empennage. The block had to be carved into a fuselage; the propeller had to be carved too, and with luck, this contraption powered by a rubber band, would fly a few feet. Later on, I discovered the magnificent range of Keil Kraft kits. At five shillings and six pence, thiswas every aviation nut’s dream. I built most of these kits over many years and even flew the scale Gloster Javelin successfully with a Jetex unit fitted, and a rudimentary control line system. No active controls except for level flight in a small circle. The Jetex pellet would burn out in about 8 seconds, so flights were short, but realistic. The Jetex motors sounded very much like a small firework rocket. I also converted a Keil Kraft scale Aeronca to electric power! Using a small toy car motor, a centre pole with two small ball bearings at the top, a cm or so apart, one negative and one positive, linked to my electric model train transformer. Each of the two control line wires was linked to a ball bearing and thus provided power to the motor. By slowly increasing power through the train transformer the plane would take-off and fly in perfect level circles. This was a massive and impressive success for my school buddies, who loved to fly the Aeronca in this set up.
The completed Skyjeep, detailed with a permanent marker.
This was unfortunately not so for me. I think this kit will be a challenge for the inexperienced builder. The fuselage formers proved to very brittle, which required some finicky repair work. With hindsight I should have put cross braces over the formers prior to assembly. The stringers provided in the kit also left much to be desired. The wood was just too soft and I replaced most of it with my own cut stringers. I still have a tool, especially made for this. How many of our SAMAA members have seen one and if so, knows how to use one? Several positive aspects of the kit, is the provision of additional parts for a 100% scale model, with a smaller stabiliser and scale propeller. I built the flying version, bigger tail and large propeller. Shortly before commencing with covering of the model, I came across a video on using tissue, produced by an Italian aeromodeller. His technique is to first give the total bare balsa frame a light spray of clear dope. Then, sand down with the finest sandpaper you can find. He then uses a glue stick on the framework. In the case of a wing, the central rib, leading and trailing edge and tip rib. The glue is applied liberally. He then mists the pre-cut tissue with water and then apply the semi wet tissue to the framework. The Guillows Edge kit came with real Esaki tissue. When wetted in this fashion, you can actually stretch the tissue over the framework and work out most of the wrinkles, since you can lift the tissue, pull on it and re-attach thereafter. Once dry, you end up with a drum-tight surface, which you have to pin down to prevent warps, when you spray it with clear dope. The end result is in the pictures. To conclude. Once again, model aircraft kept me sane, like so many times before, during the current tribulations. Cheaper than a psychiatrist and a lot more pleasant too. Try it and send me your contact details. I will invoice you sympathetically for my sound curative advice. Enjoy and fly safe.
But, I digress. When Covid forced us into lockdown, I regressed into a young boy again. Took out my stack of balsa, tissue, modern glues, such as cyano, glue sticks, and Tite Bond, as well as the piles of aeromodelling magazines with plans, and commenced building real stick-balsa-tissue planes again. Not only did this keep me sane, but it also refreshed basic building skills and I even learned some new tissue covering skills. My first project was a 50cm Cessna Bird Dog. This one was a real memory trip and low and behold, it is a beautiful flyer too. I so wish Jack Abbot or Sieger Lampen could see this Bird Dog fly. Suddenly I also had a pang for lost friends! This little stick and tissue model took me back to the indoor flying evenings, which Jack Abbot used to arrange. And with it came the sad realization: this wonderful hobby of ours, is dying a slow, but sure death! I think I must put a challenge out, let's see whether there are any other SAMAA members who can still build a real stick and tissue model aircraft! My second model was a real challenge, a Chrislea plan of the Skyjeep! This 29cm rubber-powered model is constructed from 1mm balsa sheeting. Trim was done on the balsa with a permanent marker. This is a surprisingly good flyer. As small as it is, it is amazingly stable and looks beautiful in the air! When the lockdown was extended, I bought a scale Guillows kit of the Edge 540 from Frasers. Alan was kind enough to give me as solid discount on the kit too! Most probably he remembered my friends saying that, because of my love for all things flying, I must have been born in a nest, but from poor parents! This kit is laser cut and was supposedly an easy build.

The quarry provides ample space for RC boating activities.
Car park area provides shade for members and their equipment.
Valley Radio Control Model Club is a new-aged model club that was conceived and founded in February/March 2005. The club is situated at the Coedmore old quarry site off Umhlatuzana Road, Sea View, in Durban. The quarry was filled with water many years ago and is now a large expanse of water. The cliff face on the other side of the quarry and the surrounding bush is home to some amazing bird-life including the African Fish Eagle. A survey carried out by the local bird group has identified some 100 species of birds including fish eagles, Egyptian geese, and even a pair of kiewiets who nest on the runway and completely ignore model planes taking-off over their heads. The club has 10 flying members and 21 boating members who use the dam at the end of the runway to operate RC power boats. By agreement, flying is conducted in the morning up to 12:00 and boating thereafter. Being a small group of flying members they do cover a range of the flying disciplines which include fixed-wing of various types including the ubiquitous Ugly Stik, scale, fun-flyers etc. also flown are helicopters, drones, and the occasional glider. During lock-down no flying was undertaken per the regulations but with the help of SAMAA and the opening of the regulations, flying has now recommenced and in the first weeks two new planes by members having their maiden flight. Being a small club we do not have any issue with and are able to comply with social distancing and numbers on the field at any one time. Now that inter club visits are allowed we welcome any flying visitors who can contact our club webmaster André at... webmaster@vrcmc.co.za
Two of our members’ models.
Facilities are rented from the Durban Corporation for a nominal annual rental and the members undertake the maintenance and grass cutting themselves. While no buildings or formal facilities and structures are on site, there is a tree-shaded parking area overlooking the dam, a pit area again shaded by trees, and a grass runway of 180m length giving us a location of peace and quiet to be able to enjoy our passion.

Die winter reenvalstreek van Wes-Kaap het goeie neerslae vanjaar gehad. Sneeu op die berge suid van Ceres is hier ook sigbaar.
Lede van sommige klubs het hulself besig gehou tydens die grendelperiode. Van Peter Brewis by die Ceres Model Aircraft Club, kom hierdie brokkie nuus: Ek dink julle sal die twee fotos geniet.So lyk dit by CMAC op Woensdag 15 Julie. Die "Kaap van Storms" het beslis kom kuier!
Being a small club, the members are most helpful of each other, and support for the novice flyers is one of our fundamental aspects. Often having two planes in the air at the same time is almost considered congested airspace! We are also spoilt by virtue of the location, in not being restricted for space, or having issues with neighbours objecting to us practicing our hobby. We do practice normal respect and compliance with SAMAA rules and regulations. SAMAA News Issue 3 of 2020 - Page 6

Well, we seem to be getting things moving back to normal again here in South Africa and at my club - Walker Bay Radio Flyers (from Terence Lesser). I have been involved getting the South African Model Aircraft Association (SAMAA) COVID-19 Management Plan drafted and pleased to announce that today, yes today, Sunday 5 July, we got our Certificate of Compliance, and preparing mandatory signage for our opening later this coming week.
A bit late, but here are some pictures taken over the last weekend, 19 and 19 July. We had two superb days down in the Cape and many of our members made full use of the opportunity to get out and do some flying, in what can only be described as the perfect winter’s day. Well, two of them actually!
Thanks to all who made this possible; our Chairman Norman de Villiers steered us through the storm on VFR rules. In addition to this, our WBRF work party, whilst adhering to social distancing, laid the new BotRiver field runway topping, in the form of a heavy density fabric cover, biggest carpet I’ve ever seen!

Darren Kelly en Morné Swaneoel vlieg albei 1/6de skaal MB326 Impalas in twee verskillende Silwer Valke kleurskemas, en Glen Roberts vlieg sy Vampire, 'n SAAF voorganger van die Impala.
Darren Kelly se MB-326 (Italiaanse Aermacchi-produk, vervaardig deur Atlas Aircraft Corporation in Suid-Afrika (tans Denel Aviation).
Darren Kelly het onlangs sy 1/6de skaal AB Models MB326 Impala gemaiden. Die Impala, aangedryf deur ‘n 8kg Behotec turbine, het foutloos opgestyg en gevlieg, gevolg deur n perfekte landing. Darren het die bou van die Impala, asook die verfwerk alles self behartig. Morné Swanepoel het ook van die geleentheid gebruik gemaak en met sy vier jaar oue 1/6de skaal MB326 Impala, wat alreeds 127 vlugte gevlieg het, die lugruim gedeel. Die Impala word aangedryf deur ‘n 10kg Jetcat turbine. ‘n Groter weergawe van die Impala word ook tans in Robertson gebou. Morné is al amper drie jaar jaar besig met die projek. Die Impala is 1/4 skaal, en sal aangedryf word deur ‘n 16kg turbine en hoër. Die vliegtuig, waarvan die moulds tans in produksie is, behoort teen middel 2021 te vlieg. Glen Roberts, nou al 'n welkome Robertsonner en nuwe lid by RRF het ook onlangs sy 1/4 skaal Vampire gemaiden. Glen, 'n baie bekende in die model vliegtuig bedryf, is befaamd vir sy uitstaande bouvernuf en skaal detail, waarmee die Vampire beslis kan spog. Die Vampire word aangedryf deur ‘n16kg Wren, en het met heel gemak die lug in opgestyg, gevolg deur ‘n baie suksesvolle landing.
Detail op Vampire van Glen Roberts verbysterend. Hoogste vakmanskap!

SAMPE and RC Skydiving Part 1
Say hello to radio-controlled Skydiving! We tend to become fixated on fixed-wing and rotating wing models, and perhaps do not notice this exciting branch of our hobby and sport. This information piece will give SAMAA members a bit of insight into the marvellous world of model skydiving, how it is practiced, managed, and being developed in South Africa. Worldwide activity is increasing, and with the right guidance, this may become another of the international competitive disciplines in the FAI/CIAM house. These little dudes are fully-equipped, with working scale parachutes (or canopies).
Safety rules • An RC skydiver will always be fitted with a working safety device/pin, and the skydiver will comply to technical specifications (refer SAMPE competition rules for RC Skydivers). • An RC skydiver will never be dropped out of the designated flying zone of a specific venue or club. • An RC skydiver will never be dropped overhead any people or property. • For an event, the “drop zone” or “drop circle” might be set up outside of the designated flying zone of the venue or club, to facilitate proper landing approaches.
Never to be dropped over people or property!
SAMPE will operate under all rues and regulations set out be the SAMAA, with the addition of the following: • Events and competitions will be managed under the document “SAMPE Competition Rules for RC Skydivers” • Events will be internally organised at local clubs, and will operate within their specific rules • Fly-ins or events organised for spectators, will be registered as per SAMAA standard event applications and approvals • All SAMPE events will take place at SAMAA-registered sites • All SAMAA and SAMPE safety regulations and procedures will be adhered to at all registered events • To receive SAMPE membership, a pilot must first be a Ppaid-up member of the SAMAA • To operate an RC Skydiver without assistance, the pilot must hold a Free Fall badge (Solo). It is not necessary to hold a SAMAA fixed-wing solo rating, but the pilot may not operate any other craft other than the RC Skydiver. Pre-flight check, and verbal test • A pilot must be familiar with all the components and workings of an RC Skydiver. This must be explained to the instructor • The pilot must be able to pack the parachute correctly, with no assistance • Special attention must be paid to the attachment, and give a description to the instructor on the working of the safety pin and safety equipment • The pilot must be able to attach the RC Skydiver to the aircraft with no assistance, explaining to the instructor the working of the safety pin attachment to the drop plane. Explain also all the other safety requirements. The engine of the drop plane must not be running at the time of attachment, and electrically-powered aircraft must not have the throttle armed.
Careful attention to folding/packing the parachute, and attachment.
• The pilot must do control checks after attaching the skydiver to the aircraft, and confirm to the instructor, the removal of the packing rope from the skydiver • The pilot must be familiar with commands between him and the drop plane pilot, and be able to explain this to the instructor • The pilot must explain to the instructor how to read the wind, and to direct the drop plane pilot to the correct drop location point and height, in relation to the wind direction. He must also demonstrate the drop command (Release now!) at the appropriate time. After this explanation, the test starts, and the pilot of the drop plane takes-off as directed. Drag, velocity, and gravity The RC Skydiver is taken to altitude by the drop plane, and is released. Drag is a function of speed; as the skydiver accelerates, the drag increases, until the force of drag is equal to the force of gravity. This is terminal velocity, and the skydiver will no longer accelerate, but will keep falling at this speed. The parachute is opened, and suddenly the drag is much greater than the weight. So, the object now decelerates, until drag is equal to weight again, and a new terminal velocity is established.

Note right from the beginning, and the “beer belly“ filled with lead ballast, and less problems will occur during rubber bands that keep legs in the descent. The faster your plane desired position. flies during release, the more problems will occur during free fall. The jumper needs more time to stabilise.
Now for some principles with respect to the jump box. Its main job is to hold the jumper safely during transport and eventually release it into free fall. As a rule of thumb, your jump plane should be a really docile model with a bit of extra power. A span not in excess of 3 metres is ideal for transporting the aircraft to the flying field. If the span is above 2m, you´re usually on the
For dropping the jumper, you are a team in the true sense of the word. Agree on the point where you want your jumper to be dropped, before take-off. If there is any problem during approach, go round and try again. The aircraft pilot must always announce the drop with a clear “GO”, or the like. Of course, any ordinary pilot who can control an aerobatic model, is able to take your jumper up to the desired altitude absolutely safely.

To be on the safe side, one would normally deploy a parachute with the brakes set to a certain extent. A non-braked parachute immediately starts to move forward and downward once it’s fully open. 1. If canopy stays in this position right after opening, make the steering lines a bit longer. 2. Canopy should not move beyond position 2, before it is pulled back to its top position by the jumper. 3. If canopy gets as far forward and down as shown here, the steering lines must be shortened for safety reasons.
If the jumper keeps spinning clockwise (seen from above), use the left arm to stop the spin.

If you mount your box with carbon tubes, use a diameter of 10mm. The cut-outs at the rear end are for the rubber bands that keep the legs in the “up” position. Use a big canopy lock and a wire bracket to capture and safely hold the ring at the end of the strap that holds the jumper. The strap should be about 25mm wide, and just long enough to firmly hold the jumper in place. The system works best, when the strap runs across the chest of the jumper, fairly close to the armpits.

The pilots briefing...done before every competition.
The judges’ set-up for the day.
Charl Jooste’s Extra coming in to land.
On Sunday 23 August, LSA pilots had their first competition since the easing of the lock-down regulations. With 12 pilots entered, they were in for a packed day of aerobatics. With a light wind blowing, it was time for the traditional pilots briefing. The first class in large scale aerobatics, is known as Basic. This class is specifically recommended for novice pilots who may be flying in their first competition. Three new pilots featured, and we saw much action. With the wind starting to pick up, it pushed pilot and machine to the edge. The class was won by Geoff Dale with a score of 1000.0. In second place was Juandré van der Schaar with a score of 841.5, and in third place was Charl Jooste with a score of 830.9. Then came Sportsman, which also had two new pilots flying in their first competition; Chris Parker and Daniel Finch. Both flew excellent rounds, but by the end it was veteran pilot Myles Hasenbroek who took the honours in a tightly-contested class. The final scores reflected Daniel Finch on 943.0, Chris Parker scored 980.0, and Myles Hasenbroek scored 1000.0. When asked afterwards how much practice he put in, Myles just laughed and said he at least ran the engine the Saturday before the event!

The next class was Intermediate and only one pilot, Justin Gomersall participated. Justin flew his Katana and showed us that he has been flying large scale aerobatics for a while with his excellent skills. Justin was also the organizer for the event, so if he was not flying, he was running up and down. In the end, Justin scored a 1000.0 Then followed Advanced, with Ian Edwards and Stan Fincham competing. With both pilots calling for each other, it was a close class and the scores at the end shows there is not too much separating the pilots. Ian Edwards scored a 1000.0 and Stan scored a 870.9.

The last class was Unlimited with only Danie Potgieter. When asked before his first flight what he thinks his chances are of winning, he said “I'm only aiming to finish in the top 2". Danie demonstrated why he was national champion a few times. His final score was 1000.0. After the flying, everyone braaied while exchanging their flying stories. The next time these pilots will fly, will be at the Nationals on the weekend of 24-27 September.

The new season kicked off with a good start at Barnstormers Model Flying Club. This round was a bit different than usual since Covid-19 was upon us and extra precautions were taken during the event. This however, did not stop our eager pilots to come out on race day and brush off the rust on their flying skills after a lengthy lockdown period of no flying. All social distancing rules were obeyed with extra precautions in place, and race day went on without incident. A total of 12 pilots participated in this round, 8 open and 4 sport pilots. We were separated into 3 groups of 4 pilots which meant heats would go quickly and everyone could get in a lot of flying. We flew 2 practice rounds, 12 qualifier rounds and the usual 3 final rounds. The track for this round was a relatively simple one. The first round of every season starts off easy and progresses in difficulty and technicality as we approach nationals at the end of the season. The track was fast-paced and also quad friendly with no cube or dive gates. The pilots loved flying the track and were picking up fast times towards the last few qualifier rounds. It was a fantastic day of racing with beautiful weather and everyone had a great time. We want to thank Barnstormers for the use of their FPV Park and RCEdge for the track setup and timing. A huge thank you to all the pilots who came out to race and congratulations to all the pilots who took podium finishes. Special congratulations to Chris Proenca, who not only took the win of the day, but was also voted in as the new Gauteng representative for FlyFPVSA. Stay safe everyone and we will see you at the next race.

Blast from the past! In today’s fast-paced world, we all too often neglect to honour the achievements of our pioneers, while we tend to revere the ones who are seeking eternal thermals in Elysian fields! A Blast from the Past, will show pics of some of our pioneers, present and past, and we hope this will inspire our senior pilots to contribute historical pictures for the SAMAAs History Preservation Project. Unlike most other hobbies, aeromodelling in South Africa has always had a competitive aspect. In 1926, Alan Morris, from East London, built model aircraft from bamboo and oiled silk. One of them was a Warneford Demon, and from the beginning, the object was always to see how far, and how long the rubber-powered model could stay airborne. By 1932, activities had progressed to a point where the Argus newspaper sponsored a model aircraft competition, at the Wingfield aerodrome, near the Cape Town suburb of Goodwood. A Mr John Butler won the competition, with a model that was judged as the best constructed, and it was able to make a flight of 8 seconds. The second-placed model flew for 9 seconds. It is recorded that regular activity by a group of Cape Town aeromodellers kept the movement going, including one of the founders of the SAMAA, Viv Gracie.
Simultaneous activity was recorded in other centres of the Union, and by August 1937, aeromodelling was so well established that a team of four fliers were selected to compete in the Wakefield Cup (for rubber-powered models), at the Great West Aerodrome (present Heathrow), at Hayes in Middlesex, England. The four of them could not attend in person, but the models were crated and shipped to England, to be proxy-flown by English fliers. Howard Endean’s model was flown to 27th place, and Phil Dalgety’s model attained 31st place. The models of the other two, Messrs Harker and Garvie were unfortunately destroyed before the competition. For the next two years, there was increased activity all over the Union, and SA was represented twice more at the Wakefield Cup until August 1939, when the event took place at the Aviation Golf Course in Bendix, USA. The world was plunged into war a month later, and there was a lull in activities also in South Africa, and only in 1946 did general aeromodelling and competitive activities resume. Unfortunately not much visual material exists of those early years, and gradually, a few bits of historical material are uncovered. Like an entry in the Excel worksheet of the second post-war Nationals in 1947, “at the Woodmead Airfield”. None of the older generation of full-size pilots had any idea of an airfield in Woodmead, and I can concur with this, since the present Sandton suburb of Woodmead is pretty undulating in topography, and hardly suitable for an airfield. However, further research indicated that this was actually the Wendywood motor racing circuit, located since 1936 in the present location of Kelvin. The circuit was named after Lord Earl Howe, and when racing resumed after the war, the accessibility to and from the site posed problems for spectators, and the Rand Grand Prix of 1947 was the last event to take place. The site then became available to model flying enthusiasts, hence “Woodmead Airfield”, long before the M1 highway was constructed, now separating the suburbs of Woodmead/Wendywood, from Kelvin.

Slowly, life is returning to a semi-normal state. Most businesses have opened their doors, schools have reopened for some grades, inter-provincial travel is now possible, and pretty soon, international travel may again be possible. One may even visit guest houses, B&Bs, and other establishments, an industry which has been decimated during the height of the lock-down period. I don’t smoke, and I enjoy the occasional glass of wine, so the prohibition did not have an adverse effect on my life. But the draconian regulations imposed by the SA government has left many industries, businesses, and establishments crippled, and for a long time to come still, is my guess. Like the former president, I cannot comprehend the numbers of how many millions and trillions of Rands have been covertly channeled to the pockets and vaults of criminals, who appear to be thriving in times of crises. I see reports of national championships taking place in European countries; their flying season is rapidly coming to an end, and many countries have scheduled team selection processes, to be in a position to prepare for FAI Class 1 events in 2021 (world and continental championships). In our own country, aeromodelling activities are picking up, and a few regional competitions have taken place. The relaxation of the COVID19 regulations have made it possible to hold the deferred Power Nationals, now at the end of September. At least one of the disciplines may be able to use the Nats as one of its team selection events, so that an RC Aerobatic team could qualify to participate in the 2021 world championship in Muncie, Indiana, in the USA. What is a little concerning, is that I have seen no information on this event, and time is fast running out for the US organisers (the AMA). The date and venue is a certainty, if Mr Covid does not flex his muscles, and the US introduces follow-up measures to contain the spread of the virus. Let’s wait and see. Other events are also possible, provided the number of attendees is effectively managed. Large gatherings are still not possible, but in my opinion, with all the protocols in place, a fly-in is entirely possible, even with camping! One just has to be sensible, and apply common sense, and not be reckless to the potential dangers of a dreaded disease. Organised meetings are gradually taking on a new face...Zoom and Teams have become new words in our vocabulary, and traditional face-to-face meetings are being replaced by virtual meetings, which in itself bring some cost-saving. The FAI General Conference for 2020 will not be a traditional business meeting, but a virtual one, naturally with some challenges. Considerable thought had to go into voting processes; how to conduct voting, counting, ratifying, announcing, etc. In April, the Plenary Meeting of the CIAM (Commission for International Aeromodelling) had to be cancelled, due to the world wide travel ban. This meeting is cancelled entirely for 2020, and several virtual meetings have taken place to date, to decide the way forward for rule change proposals that were on the agenda, and election of office bearers, and awards, and assignment of championships, and a host of other business that is usually transacted at these meetings.
