Dec 6 1952 to Dec 7 1952

The interim meeting of the Model Committee held at Paris, on the 6th and 7th December, 1952

Only an Extract of C/L issues discussed is shown. Horizontal rules indicate material left out.

THIS meeting was the best attended of the series so far, representations from the following countries being present:-France, Great Britain, Switzerland, Belgium, Holland, Denmark, Sweden, Spain, Jugo-Slavia.

The director general of the F.A.I. Mr. H. R. Gillman, and the secretary of the committee, M. Guillemard, were also present.


The first business of the meeting was to discuss the international calendar for 1953, and decide on the contests to be sanctioned.

A discussion on the proposition of Great Britain to limit the teams in all international contests to four and one team manager followed and when put to the vote this was carried unanimously and will apply from January 1st, 1953.


The following items which had been placed on the agenda by various countries were then discussed:

Alterations to the Code Sportif

Only the items for C/L are included

(g)  In view of the difficulty of judging the square loop manoeuvres in acrobatic contests Belgium proposed that this figure should be eliminated from the Schedule. This was carried.

The following items were tabled by the secretariat.

(1)  Limitation of cylinder capacity to 5 c.c.. For Championships in circular flight. The Belgian delegate reminded the meeting of the reasons which gave raise to this proposal in Madrid.

The Committee decided to retain the three categories but in order to case the situation when deciding the World (Championship in circular flight, agreed that one category of cylinder capacity be adopted cacti year thus in 1953 the Championships will be for Class 3, in 1954 for Class 2, and in 1955 for Class 1, in 1956 Class 3 again and so on.

Note: This means that in 1953 10cc wqas the World Championship Class and 5cc in 1954. After this the standardization to one 2.5cc class became the new rule.

(4)  The question of rules for team racing contests was raised and it was agreed that a set of rules should be drafted as a result of the experience which will be gained at the Dutch and Belgian contests this year.

(6) The Academy of Model Aeronautics of U.S.A. submitted several propositions concerning C/L speed contests as follows:

(a)  That the diameter of the cable; for C/L models should be specified.

This was rejected on the grounds that it does not take into account the specification of the material. It was the-opinion of the meeting that a test load of 20 times the weight of the model applied to the lines was the only safe method.

(b)  That the maximum cross section rule be eliminated.

This was rejected.

(c)  That the minimum and maximum loadings at present specified should be deleted.

The Committee considered the rules satisfactory as they stand and no change is contemplated.

(d)  To modify the rule that the model must always remain above the horizontal plane and substitute a maximum flying height of 15 ft. (4.672 m.) for Class 1 and 20 ft. (6.096 m.) for Classes 2 and 3.

This was defeated.

(e)  For timekeeping the Academy proposed the use of three timekeepers with 1/10th second watches and that timing should commence after the model has completed three laps. It also proposed a maximum variation of 2/10th sec.

This was considered less satisfactory than the existing rules.

(f)  The Academy expressed the opinion that second class watches are an imposition and unnecessary. This was considered together with their proposition that the watches should be given a check over a three hour period before and after the contest with a maximum error of 6 sec.

The committee felt that the Academy was confusing record rules with contest rules and that the two conditions are adequately covered in the present regulations.
