Fifth RC World Champs

October 1967 American Modeler

October 1967 American Modeler magazine cover Table of Contents

These pages from vintage modeling magazines like Flying Aces, Air Trails, American Modeler, American Aircraft Modeler, Young Men, Flying Models, Model Airplane News, R/C Modeler, captured the era. All copyrights acknowledged.

An article covering a major R/C competition in one of today's modeling magazines would be 90% color photos and 10% text. In 1967 it was just the opposite, as this coverage of the "Fifth World Championships of Air Gymnastics for Remote Controlled Aircraft" shows - and there is no color to be found. Maybe the old adage about a picture being worth a thousand words balances the equation. 43 pilots represented 17 nations on the French island of Corsica. Phil Kraft and his own design Kwik Fli IV ruled the day. France and Germany took second and third place, respectively. If you like reading about how the early pattern radios, airplanes and engines were combined to wow the crowds, this one is for you.

Fifth RC World Champs

Seventeen nations - and 43 pilots - vied in hotly contested meet at Corsica, sponsored by the Aero Club of France. Using models powered by the big 60's, but distinctly smaller than those flown by the competition, the United States' consistent performance gained both individual and team honors.

Fifth World Championships of Air Gymnastics for Remote Controlled Aircraft; this impressive title is a free translation of the French wording on the cover of the official booklet handed out to all who arrived at the French island of Corsica on June 21, ready for what proved to be the largest of the five RC World Championships held so far. A large majority of those attending the affair spent the night of June 20 at the French seaport resort of Nice; around noon Wednesday all hands gathered at a central point for a reception tendered by the mayor, then piled into buses for a trip to the Nice airport. Reception, bussing and the airlift to Corsica were part of the "package" arranged by the Championships organizers, which also included the five day stay in Corsica, board and lodging and transportation back to Nice on June 27th.

This competition had its ups and downs. On the "up" side was a full week of perfect flying weather - warm to hot days (on Sunday, the early morning "heat reminded us of the Nats at Dallas!), cool nights, generally low winds. Worst of the "downs" was serious interference on Friday, June 23rd, first day of official flying: this was, in fact, the first such interference which has ever been experienced at an RC Championships - more on this later.

Upon arriving at the very modern Campo dell-Oro airport of Ajaccio, Corsica, a first impression was of the fine climate (especially appreciated by many travelers from parts of the U.S. who had experienced a cold and wet spring - which had also afflicted England and much of Europe). Next we were awed by the mountainous terrain, some of the higher peaks of which appeared to carry remains of winter snow! The airlift from Nice was via two planes; one was a huge double-decker Breguet 937, a four propeller job with ample room for the many model cases which had collected at Nice. The upper deck of this plane had seats for many of the RCers, while others embarked on an Air France Caravelle for a considerably faster and more luxurious trip. Information pouches were handed out to all at Campo dell'Oro, after which buses carried all hands to their lodgings. The vast majority had a trip of about seven miles along a very narrow and winding road, terminating at the "Marina-Viva," a large resort which in the States would be termed a motel. Though a little early in the vacation season, there were already a hundred or so persons at the Marina, to which were added some 150 or so RC flyers, officials and supporters. The latter category includes those from any country who have no direct connection with the meet, but just a love of flying and a desire to root for the "home team" - wherever home might be.

Even though interference caused considerable delays, however, it was found possible to finish the first official round of flying on Friday, June 23, not long after 6 p.m.; start of flying was therefore postponed till 8 a.m. on June 24th and 25th.

While there is little model plane activity on Ajaccio, there is a very active flying club; the attractive headquarters building of the Aero Club de la Corse was a mecca for all participants during the meet, and one of the two club hangars was the main pit and storage area for planes.

U.S. Team members had no problem getting their large model boxes to Frankfurt - terminus of the over-Atlantic airlift arranged through AMA. But here problems arose; Wierick and Spreng found that no planes going to Nice had room enough to carry the model boxes! (Kraft had shipped his box directly from California to Ajaccio - which was fine, except for the fact the box arrived at the airport at the last moment, and just in time for the practice flying on June 22!). Through intercession of various airline officials, the two flyers were allowed to take their two planes apiece onto the aircraft sans boxes, a most unusual concession. Incidentally, while checking their boxes at Kennedy Airport in New York the boys had proof that RC modelers are literally everywhere; printed on a corner of one box was a message saying "Win the World Championships with these models, then give 'em to us" and signed the L.I.D.S.- a prominent club that evidently covers Long Island like a blanket!

Due to uncertain transportation between the Marina and the flying field, many entrants, including the U.S. team, rented their own cars. Upon arrival at the Marina, it was found that the management had banned battery charging! Doubtless completely unfamiliar with model planes, the manager probably envisioned a heavy-duty auto battery charger running in most every room, to put a heavy drain on his meager voltage supply. It's likely a lot of "bootleg" charging went on that first night! There were ample charging facilities at the work hangar, of course.

As is usual practice at such meets, a full day of practice was allowed, June 22. and each member of the 17 teams present got approximately 15 minutes for test flying; 43 pilots started the meet. In a determined effort to come out on top, the German Team had arrived at Ajaccio some days earlier, and were doubtless very familiar with the field and the flying conditions by the time the meet started. Fortunately, they had brought with them a most complete monitoring system to check for interference. The setup even included an oscilloscope for observing incoming signals, and a tape machine for recording same, if desired. All this equipment was in a small station wagon, but was used only on and off during the Thursday practice day. It turned out that this was the only monitoring equipment at the meet; apparatus which had been requested from the French government failed to arrive in time for the meet (as did some other essentials, such as meal tickets!).

Since there is no real contest pressure during practice day, Press photogs try to take as many photos as possible then. This led to the hassle that seems to come early in every World Champs (and usually at every U.S. Nationals tool), and soon the Press representatives found themselves confined some 100 yards or more from the flying spot - an impossible situation. As is usually the case this misunderstanding was eventually resolved to the satisfaction of all - but why can't these things be anticipated beforehand and suitable arrangements made before many hard feelings are generated?

During practice it was feared that many teams would not have sufficient fuel to get through the meet. Our own team had plenty, and Manager Jerry Nelson offered to supply anyone who ran short - a gesture that was most appreciated.

During practice day we had a good chance to look over planes and equipment, as well as to assess the level of competition. It was apparent that this was to be a "proportional Championships," for our data showed that every entrant flew propo in the meet (some may have had reeds in their second planes, of which there are not complete records). Out of 41 flyers, 19 used U.S. equipment of various makes, Bonner Digimite being most numerous with six users. The German Simprop system was most numerous in the meet, with ten users. Multi propo equipment is no longer made in South Africa, and this team used U.S. apparatus throughout. Digital apparatus is now made in France (Radio Pilote, being marketed by 2nd place Marrot), and in Sweden (Micronic - used in Corsica by at least one Swedish team member). Though there is quite a variety of English propo equipment, all British team members used U.S. equipment; this team was 100% reeds at the last World Champs.

Not many other flyers had planes as small as the U.S. team - and many were far larger. There were several copies of Fritz Bosch's Super Delphin, a really big plane. Just about every plane was a low winger, except for the Satanus II of Marrot, and a similar model by his teammate Cousson; these are shoulder wingers with rather thick airfoil, and Marrot's well-deserved second place testifies to their flying prowess, at least in the FAI pattern. As a holdover from the 1965 Championships, there were a couple of Brooke Crusaders - one modified with a swept wing.

The U.S. Team flew more or less new planes - much different from those flown in the Eliminations last fall. Winner Phil Kraft flew a version of his Qwick-Fli, which in fact, sported a three-year-old wing, but this Mk III model had an upright engine, lower thrust line, deeper rear fuselage and much larger rudder area than the Qwick-Fli II. Power was an Enya 60 II, and radio equipment-well, what do you think!? Fourth place man Doug Spreng had a rather small taper-wing plane he calls Twister, powered by ST 60, while 10th-placer Cliff Weirick flew the scale Chipmunk with Veco 61. The latter attracted a great amount of attention due to its sleek scale appearance. Cliff used flaps to slow down landing approach and used interesting take-off technique with only partially open throttle, then opened right up immediately after the machine broke ground. This helped the model from nosing over.

Engines were just about 100 percent 60-61 (one Fox 59 listed). We counted 11 each of Rossi and ST 60's, and eight Mercos as the most popular. Many engines were fitted with mufflers; several countries have mandatory muffler rules, among them Sweden. However, the Swedish flyers operate in a much cooler atmosphere and had some overheating troubles in Corsica. Engine troubles plagued many other entrants as well; in this "sudden-death" sort of competition (where every single flight counts, and one poor flight for any reason at all can drop a flyer far down in the standings, and can cost his team a top place) reliable power is every bit as important as reliable radio. We noted that a good many competitors were using the Kavan carburetor, which is gaining quite a reputation in the U.S. too.

The judge rotation system was the same as inaugurated at Sweden; six judges (plus several alternates in case of illness, etc.) were kept on duty, with four judging every flight. After any group of four had judged four flights. two dropped out and the other two took their places. Overall, this meant that a judge was generally working for eight flights and off for four. Order of flying was switched each day too, though the same basic order was retained for the three official flying days. Thus, on Friday, flying started with Tonnessen of Norway first; Saturday, Tonnessen dropped to 20th, and the bottom 19 fivers on the Friday list were brought to the top. Sunday another such shift was made, resulting in Kraft flying first. This system worked fine. though the word soon went out as to which judges were considered "tough" and vice-versa! But it assured that no fiver would get the same set of judges twice during the meet. The only real problem was that when a flyer had a "delay" (which entitled him to a second try at the end of the round), the same set of judges had to be assembled as were on duty when he had his original try.

5th R/C World Championships Score Card - Airplanes and Rockets

5th R/C World Championships Score Card

The judges came from the U.S. (Maynard Hill), Belgium, West Germany, Great Britain, Czechoslovakia and France, and are appointed by the CIAM, the modeling division of the FAI. Similarly selected were the three jury members, with Walt Good from the U.S., A. Roussel from Belgium, and Henry J. Nicholls from Great Britain.

Interference raised its ugly head early on Friday, on the flight of Fritz Bosch, who was second man up. He had gone through eight minutes of his pattern when it became evident he was in trouble; he was able to land safely and the German monitoring setup, mentioned earlier, detected strong interference very close to 26.995 on which he was flying. The signals evidently came from a long distance, as they would fade in and out; but when "in," the level was very high. During the day, the interference would at times register a stronger signal on the monitor receiver than would the RC transmitter on the flight line only 150 feet away! All sorts of signals were picked up -voice, code and so on. Unfortunately, the voices could never be identified, but it would have mattered little if they could have been: they doubtless came from much too far away to just call the interfering station on the phone and ask them to please sign off so the model meet could continue! This is the first World Championships which has had any real interference trouble; it is likely to be even worse two years hence in Germany, since the sunspot cycle will be at its peak then - and high sunspot activity is what causes worldwide problems from "skip" signals bouncing off upper atmosphere layers. But what can you do?

As the day wore on, the interference faded considerably, so that by late afternoon it was not a problem. Some contestants had been able to fly in their assigned position in the lineup by shifting to less-bothered RC spots. Others could not do so for various reasons (some just didn't have the necessary crystals to do so) and were dropped to the end of the round, when they flew late Friday afternoon.

The fact that the monitoring equipment was of German origin-and in fact, had been brought to the field by a German propo maker (Simprop ) - posed some delicate problems in international relationships. The jury finally solved this and soothed all ruffled feelings by permanently posting one of their number (Walt Good) at the monitor. All day Friday, every transmitter was checked for exact frequency as soon as it was brought from the Impound tent to the field. It was then switched off, and the frequency checked. If no serious interference was detected, a green flag went up, and the contestant could feel safe to fly. If there was interference on the frequency, Juryman Good recorded the fact, and made a record of frequency, signal strength, time and other data at the moment on the tape recorder. With a red flag up, denoting interference. a modeler was free to decide if he wanted to take a chance or not (if he did, and got into trouble, he would not be given a delayed flight).

It's a tribute to the monitor equipment and its operator that not a single crash occurred despite the heavy interference - though there were several Friday caused by the usual problems - equipment and pilot trouble. There were several more crashes on Saturday and Sunday from the same causes, in heavy contrast to Sweden, when not a single plane crashed during official flying.

A modeler can enter an official protest to the jury at any time during the meet, of course; during all the worry over interference on Friday, one experienced flyer felt he was having unexplained engine speed changes during his flight, even though no interference could be noted on the monitor. This fact was taped by Juryman Good, who accepted the protest and the mandatory payment of ten Swiss francs (about $2.50). It was later reported that the flyer had changed his throttle servo - and had no further problems in this line.

With the interference dropping rapidly Friday afternoon, some contestants elected to fly on the most troubled spots, with no real problems. When it came time for Bosch to take his delayed flight, all flyers were watching intently, as he could very well have won the meet. But it was soon apparent that his engine was sagging badly, and it soon quit during a maneuver! (Later examination showed a speck of dirt in his fuel line.) It's useless to speculate "what might have been"; but Bosch got only 810 points for his very short delayed flight on Friday. His other two flights were well over 5100 points each; "if" he had scored in the same vicinity on the ill-fated first day, the German team might well have placed first. A few hundred more points could have won first place for him (provided our boys weren't inspired to do ever better than they did).

Unlike 1965, where there was a seesaw battle for first over the three days of official flying, Kraft jumped to first place on Friday and was never topped thereafter; he hit 5317, his lowest score of the three days. He was followed by German flyers Bauerheim (a veteran of World Championship RC flying) and Schmitz, the latter a newcomer. Then came Spreng at 5th and Marrot at 6th. Cliff Weirick was down at 12th. There were some surprises in this round; the South African team looked very good, with flyers at 6th, 7th and 17th. And the lone representative from Liechtenstein (first time this tiny country has entered the World Champs) was a strong 8th in the field of 42; Wolfgang Matt is only 19, flew a copy of Bosch's Super Delphin which was only about 2 oz. under the maximum FAI weight limit! And at that, he lost his landing points for being overtime.

Everyone expected the worst from interference on Saturday - and there was practically none at all, nor was there on Sunday. No one could explain why it had vanished so suddenly, as it was apparent the Friday trouble was caused by a number of stations, not just one; but that's the way the upper atmosphere often behaves, as any ham radio operator can tell you. But while there was no interference from long distance signals, there was some right on the field, as it finally turned out. The air had seemed clear when Greek entrant Papaspyros (1967 also was the first year for this country in RC World Championship competition) was ready to fly late in the afternoon. But some time after he became airborne, it appeared that he was having trouble, and the monitor operator called attention to a whistle that could be heard weakly under the strong sigs from the nearby Greek transmitter. The red flag was run up immediately, and Papaspyros was able to get his plane on the ground intact. With his transmitter off. a rather potent and steady signal could be heard, obviously a digital transmitter. An immediate search was started for one with a switch left on. It was finally found - one of two identical transmitters of flyer Cousson, both on 27.095 - the same as Papaspyros. One other flyer had been up with no problems between Cousson and Papaspyros, but on 27.255, so the switched-on transmitter hadn't been noticed - if it was on at that point. Why wasn't it detected before the Greek flyer took off? No one can say - but again an alert monitor operator caught the interfering whistle in time to prevent a possible crash.

By the end of Saturday flying, it became fairly ,evident how the top places would go - provided the holders of same fared well on Sunday. Kraft led 2nd placer Marrot (on the basis of two days scores) by some 700 points, but could still be deposed on Sunday by the competent French flyer. Spreng was up to 3rd, Bauerheim had dropped to 6th. Matt still clung to 8th place, while Weirick had risen to 9th. France and South Africa still looked good in team placings after U.S. Team Manager Jerry Nelson's charges, with Germany now in 4th, due to Bosch's strong second flight, and his jump from 40th to 30th place.

Sunday gave promise of extreme heat, and the early morning was practically windless. Fortunately, a breeze came along in mid-morning which made things .bearable (about 10 mph with gusts as high as 18). This last day of the meet brought some surprises. For one, Swiss entrant Giezendanner hit the highest score of the meet, with 5574 (Kraft dropped a little, got 5516 on Sunday). The German, Bauerheim, made his best score of the meet - 5340, and Bosch hit 5139. Matt placed 4th for the day with 5164, while Spreng and Weirick dropped a few places. The top individual scorers for the three days were thus Kraft 1st (16,496); Marrot, 2nd (15,265); Bauerheim, 3rd (14,875); Spreng, 4th (14,861); Schmitz 5th, (14,705). Cliff Weirick ended up in 10th with 13,584.

Of the Team scores, the U.S. totaled 44,941 for top place; West Germany was 2nd with 40,723, South Africa was 3rd with 39,171, France was 4th with 38,843 and Switzerland 5th at 33,130.

It was generally felt that the organization of the meet was extremely good, and the flying site and hangar areas were certainly fine. The French had set up an unusual system to record plane dimensions; each plane, after it had been weighed, was suspended - nose downward over a lined backboard and photographed. Thus a visual record was kept of wing area and other pertinent dimensions. Spectator control on the field was strict, with Gendarmes guarding the only entry gate to the flying site. The organizers had set up bleachers and considerable lengths of fencing to keep spectators back a safe distance. Surprisingly, very few spectators showed up. Perhaps the other attractions of the resort area proved stronger (like, miles of fine beaches, bikinis a dime a dozen, etc. etc.!).

Anyway, there certainly was no "spectator problem" - but at the same time, the meet organizers failed to collect apparently expected admissions to swell their sadly depleted funds. Scores were posted on the master board in the main hangar amazingly rapidly; lists of the days winners were passed out each night during the evening meal, and on Friday, we even had a score listing of those who had flown up until noontime.

Trophies have usually been awarded at the Victory Banquet, following these Championship meets, but again, something new was tried in Corsica, an open air awards ceremony conducted in front of the Aero Club of Corsica headquarters building. There we found a small platform of three different heights, the highest level in the center. As the top three individual winners were called, they mounted the platform at levels befitting their winning places, in the same manner as we see Olympic winners awarded.

As top winner Kraft took his place on the center of the platform, the U.S. national anthem was played as the U.S. flag was slowly raised on a central flag pole behind him. French and German flags were raised as the second and third place winners came to their platform spots. Then the 4th and 5th place winners, and team managers of the top three teams were called. Prizes in the form of trophies and merchandise were handed to all the top winners as they came forward, various of the assembled dignitaries assembled near the raised platform making the awards personally. All in all it was a very impressive ceremony, marred only slightly by the fact that it took quite a while to assemble everyone, and darkness was approaching rapidly near the end.

With the prizes awarded, there was not much left to do but eat at the victory banquet, held about 9 p.m. at the Marina-Viva. This banquet was in sharp contrast to the very formal affair at Kenley in 1962, and the exuberant but restrained affair at Sweden in 1965. It seemed that about half those present wanted to do nothing more than let off steam, and speeches by a few officials were simply unheard, though accompanied by flying pieces of' bread and other objects. The view of many was that this banquet might well have been eliminated!

The Championships organizers had set up a "free day" Monday, during which those attending could go sight-seeing, fly their planes at the field, etc. A reception at noon was held by the Mayor in honor of the RCers, after which buses took everyone to a nearby beach for a bounteous meal and a swim in the Mediterranean. Also, the Aero Club of Corsica offered flights in a two-place glider for only ten francs (about $2), which seemed barely enough to pay for the fuel used by the tow plane. Only a few availed themselves of this opportunity, among whom was this writer, who enjoyed it greatly.

If there were any weaknesses in the organization, it could be said they were in "communication" and transportation. While all printed bulletins released during the meet were in both French and English, few English announcements were made at the field. Probably half those attending the meet did not understand French, thus many were left in the dark as to what was going on. As for transportation, since the living quarters were quite far from the field, many felt that more frequent bus service during the day would have been most helpful. If you missed the last bus in the morning (which usually left the Marina about 9 a.m., you were on your own - and it was a long walk (or swim) to the field! As a result, large numbers of modelers and others felt the necessity of renting cars.

Included in the "package" of housing and transportation, was transport back to Nice by air. We understand that Air France covered much of the expense of the Nice-Ajaccio transportation, as well as collecting the French team members and some of the French officials, and getting them to the island and back home. The Belgians were carried from their country to Corsica and back by Belgian military plane, while the Italians had similar military transport from their armed services. The AMA was able to pay or arrange for most of the expenses of the U.S. Team all the way from California to Nice, where the Championships transportation took over (and, of course, the $40 fee covering each meet entry); much of the cost of this was covered by donations to the AMA RC World Championships fund - yes, your donations really do count!

In closing, we find it impossible to thank individually all those who labored mightily to make this a most successful 5th RC World Championships, so will simply direct congratulations to Mr. J. Ganier (Director of the French aeromodelling association - the "French John Worth") and to Dr. M. Antonetti, Vice Pres. of the Aero Club of Corsica, who handled much of the work on the Island. May all future Championships be as successful as the 5th!
