Wakefield competition requires some of the highest skill level in all of model-dom with regards to aircraft structure and covering details, engine and fuel system tuning, dethermalizer setup, trim for uncontrolled flight during launch, transition, glide, and dethermalized phases. That. of course, is not to minimize the skill sets required for other realms of model aircraft, but it seems to me Wakefield requires expertise in all disciplines in order to be a consistent winner. The 12th Nordic Championships we held in winter on Lake Vasijarvi at Tampere, Finland - above the Arctic Circle, at 61.5°N. This is a robust bunch of modelers!

Was this the greatest ever contest? Results show terrific standard in Nordic Country flying?

Since 1945, Scandanavian modellers have competed in the Nordic Countries Champs, thus creating the A/2 Class in the late Fourties. Some years later the Wakefield and F.A.I. power classes were included in these meetings. The high standard the Nordic Country teams have produced at the World Champs, and other International meetings have in no small way been due to these annual meetings as well as the all-the-year-round flying programmes run in these countries.

For the second time the Championships were held in winter, this time over the huge frozen Lake Vasijarvi at Tampere, Finland on March 20th. Due to the unusual date, the Danes could only send three men, the world famous A/2 trio of Hansens; Arne, Borge and Hans and they were delayed by ice in the Baltic. Norway has yet to reach the International standard in Wake, so they only sent A/2 and Power teams but both the Swedes and the hosts country Finland had full teams.

Rolf Hagel's Mister Max - Airplanes and Rockets

Rolf Hagel's winning power model, times were 900 + 210 + 240 + 270. Same model also won 1960 Swedish meeting with 900 + 5 x 180 seconds

An almost two mile long motor road had been ploughed to the centre of the lake, where everything including tents for models and control were ready at sunrise, as the competitors came out to trim. Events started at 8 o'clock with one hour rounds divided into three 20 minute periods for each competitor to make his flight. The sun was shining from a clear blue sky, and morning haze hung still above the ice. Beginning with a faint breeze and a temperature of about minus 2 deg. centigrade the circumstances were set for a splendid day of flying, and results were to prove it one of the finest contests ever known.

The first round saw 17 maxes for the 27 competitors including all the Finns. Thermal activity was non-existent and remained so all the day. Sometimes only very weak lift would make up to 20 seconds increase in the A/2 times. Thus the competition really gave true performances of the models, eliminating entirely the thermal lottery so common at summer time. During the second round the wind got up to 3-5 metres/second (780 feet per minute) remaining so for the rest of the day. Flyers had to make 1-1 1/2 mile recoveries for their models, and as the ice was covered with 5 inches of snow, those without skis were quite exhausted towards the afternoon.

After the second period the Finns were still having perfect maximums, and such conditions called for good still air models to make maximums, so it was no wonder that the Hansens were eliminated from the top places with their strong dihedralled low aspect ratio gliders made especially for the windy conditions always prevailing in Denmark. However, they were utilising the weather for trimming models to ultimate performance, but as one of them jokingly said "It isn't very economical to go trimming models abroad."

As the third period clearly demonstrated, the standard in Wakefield and Power was very high. In the Power class, only errors, such as fuel running out too early, could prevent competitors from making maxes. It would seem that the F.A.I. will have something to do with this class, e.g. limiting the motor run to 10 seconds to make some sense of the 3 minute maximum. This third period saw two Finns dropping slightly from maxes with their A/2s. Then followed a one hour break for a meal while the numerous public who combined their Sunday skiing with sightseeing the meeting, could see some fine practice towings by the Finnish A/2 experts, kiting their models overhead and holding them on the line indefinitely. Sweden's Rolf Hagel was also trimming his new 1·5 c.c. power model, which created some interesting high speed acrobatics having still to gain its ultimate trim.

Nordic Countries Championships Results - RF CafeThe wind had dropped slightly at the beginning of the fourth period, and the maximum duration flights prevailed through to the fifth and final period with the final result that there were 900 seconds men in every class. Bror Eimar of Sweden and Finland's Pentti Ella in A/2, all the three Finnish Wakefield flyers, Aalto, Hamallainen and Hyvarinen. Power saw five men with perfect maxes viz. the three Finns, Vienni, Jokinen and Nurininen Sweden's Hagel and Bulukin from Norway. Team placings were already solved, Finland making clear victories in all the classes and with really astounding results. A/2; 2652 seconds, Wakefield and Power each with perfect maximums of 2,700 seconds. Victory went clearly to Finland by missing only 48 seconds of the possible 8,100 seconds in the 3 classes (45 flights), more than 500 seconds ahead of Sweden. The Finns had every reason to be extremely satisfied with their record performance.

On the previous evening, team-managers had made an agreement on the inevitable fly-off. Both Sweden and Finland were already experienced in the new F.A.I. rule of continuing 3 minute flights and whilst for A/2 it seems to be satisfactory, in Wakefield and especially in Power it might even take weeks of continuous flying to determine the winner under good conditions. So it was decided to increase the maximum time by 30 seconds every flight.  

The first flight decided the winner in A/2 for Ellas' line broke immediately after launch, and the model clocked a mere 45 seconds from 40 feet height. So Eimar had no difficulties in making 179 seconds to become the individual winner. In Wakefield the three Finns decided to launch simultaneously to eliminate the possible risk of lift or a downdraught. Hamalainen didn't make his usual height during the climb and with only 184 seconds he dropped aside, Aalto and Hyvarinen making 3.43 and 4.32 respectively. The second fly-off round was expected to be very exciting, because the models had been drifting to the outer limit of the time-keepers' sight at 4 minutes. Following a simultaneous launch both models were climbing very steeply all the time but despite his longer (56 seconds) motor run against Aalto's 40 seconds Hyvarinen gained a clear edge in climbing altitude, and as the models were gliding equally well, this decided the winner. Hyvarinen made the 4 minute mark with 4:25 against Aalto's 3:35.

Bror Eimar's winning Nimbus A/2 - Airplanes and Rockets

Bror Eimar's winning A/2 made 900 + 179 being also the winner of the 1960 Swedish Winter meeting with 900 seconds

In Power, Bulukin dropped first, as his model did not recover in time after a series of stalls after engine cut-out. Next round, Finland's Nurininen dropped below the 4 minute mark, so there were only Osmo Niemi, Jokinen and Hagel to share the three top places. Niemi flew first, but somehow his model did not gain its normal altitude and he lost 18 seconds from the required 4:30. Hagel was next. His model made a fine climb, but the motor run was so close to the upper limit of 15 seconds, that it took a long time before the official timekeepers clocks had been compared to approve the flight.

It exceeded the 4:39 mark and Finnish hopes were now on Jokinen, but his elegant model did not make its best climb and it returned only 4:05 so making Hagel well-deserved winner with his original, long, three finned "Mister Max". Thus the toughest ever Nordic Countries meeting concluded as the sun was descending to the horizon. The organisers had made everything function correctly and deserved all praise. Competitors were also satisfied with the day, although all had not experienced their best day, Finland demonstrated that, for the third year in succession it is the leading country in free flight among the Nordic Countries. In 1958 Finland won everything in rain and strong wind, 1959 saw a strong thermal competition where the Finns took 6 of the possible 7 victories and now they gained 5 of 7 possible.

Sweden was also satisfied with the two personal victories, and Norway showed itself to be fast making its way up to the leading aeromodelling countries in the Northern Hemisphere.

As to the models, beginning with A/2, it was very interesting to see three A.P.S. "Sans Egal's" being well flown on the Finnish soil by their Norwegian owners. As they said, the design is gaining a great popularity in Norway. The Finns were using highest aspect ratios and small pylons in their models (made for inserting D.T. Timers in the fuselage). The winning model by Eimar of Sweden was three years old, but is just beginning to gain victories including the Swedish winter meeting with 900 seconds. The models of fairly simple construction having silk covered two piece wing joined together with two wires going through the slim fuselage.

Jeppe Wakefield by Reino Hyvarinen - Airplanes and Rockets

Winning Wakefield by Reino Hyvarinen made 900 + 210 + 240 seconds

In Wakefield the Swedes were using minimum sized compact models with small props and short motor runs varying from 32 seconds in the Qvarnstrom brothers models, to 43 seconds by Rene Johansson. The Finns were however taking advantage with their longer and higher aspect ratio winged, big-prop, models having motor runs from Aalto's 40, Hamalainen's 46 to Hyvarinen's 56 seconds. The latter's model, winner of numerous competitions, has a 4 year old prop and wing. He was the only Wakefield flyer using a clockwork d/t timer.

All power models were using the common pylon, the Norwegians having the lowest pylons. Hagel and the Norwegians had two piece wings for transportation. Common engine choice was the modified Oliver Tiger Mk. III, one flyer had Webra Mach I and another was using Enya 15D. Osmo Niemi's Pulteri, which will join the A.P.S. plan range was admired for two reasons, being the most straightforward and simplest construction, and also for having a really fine performance. As the Swedes said, his model went up like a "train on rails", so steady and effective was its spiral climb. Hagel had the most original designs, his magnificently built winning model was featuring double fins and a third fin for auto-rudder operation also using a clockwork d/t timer.

Even during the busiest times of my life I have endeavored to maintain some form of model building activity. This site has been created to help me chronicle my journey through a lifelong involvement in model aviation, which all began in Mayo, MD. There is a lot of good information and there are lot of pictures throughout the website that you will probably find useful, and might even bring back some old memories from your own days of yore. The website began life around 1996 as an EarthLink screen name of ModelAirplanes, and quickly grew to where more server space ...
