26th Annual World Wide Postal Competition, 2017-2018, Including Sky Bunny

The purpose of this postal contest is to encourage friendly participation among aeromodellers worldwide with the prime emphasis being on low-key, leisurely flying without the pressures of regular competition.  The Internet permits us to have a worldwide event in the spirit of a friendly local club contest. A wide variety of events are offered including classes for types and sizes of models which have been overtaken or outclassed by modern developments or are perhaps too small to be considered for serious competition work, such as 20” and 25” Rubber, Sky Bunny and Cloud Tramp, many of which can be flown at any time on smaller local sites without the necessity of travel to more formal contests at larger areas.

It is hoped that these simpler categories will encourage less experienced modelers to make flights, compare notes and improve their flying skills. To this purpose, I have added the Foam Plate Rubber Band Powered Airplane event.

Flights may be made outdoors between July 1st 2017 and June 30th 2018 inclusive; it is not required that all flights in any event be made upon the same day but each is to be pre-nominated as official. The general format (with exceptions as noted) is for three or more flights to the specified maximum; after three (or more) maximums are achieved, further flights will be made to a higher maximum, increasing by specified increments until the model fails to reach the duration target for that flight. The final score will be the total of all flights, recorded in seconds; the purpose of this scoring system is to reduce the possibility of models being lost in an unlimited flyoff and as flights may be made at any time within the contest period it does not entail unduly arduous flying sessions to complete same. In classes where maximum sizes are established, the span shall be measured as per plan, not as projected span.

A maximum, called a max,  is the maximum time that may be recorded for a flight, without respect to the actual flight time on the watch being over the maximum. To clarify the concept of maximums, consider an event which requires six flights with a maximum of 60 seconds and a 30 second increment thereafter. If you make six flights and all are over 60 seconds, those flight times are each recorded for scoring purposes as a 60 second flight. The total score at this point is 6 x 60 = 360 seconds. If any of your flights are less than the 60 second maximum, that flight time is recorded and the recorded times are summed for your score. Only if you make all six maxes do you qualify for the next flight, which will have a 60 + 30 = 90 second maximum. If you don’t make the 90 second max, you sum your times so far for your score. If you make the 90 second max, you may make another flight to a 90 + 30 = 120 second max. If at any time, you don’t make the max, you record that lesser time and sum it with all previous flight times for your score. You make no more flights if at any time you fail to make the max for that flight.

Report all times recorded for the event, do not report only the final score. I have had submittals of times from other contests listing only final scores. Different contests have different rules for flights and scoring. All flight times are required to verify and make transparent that scoring is done according to the WWP rules.

‘Vintage/Oldtimer classes are for designs authenticated to have been flying outdoors prior to December 31st, 1950, even though plan publication may be of a later date in any kit, commercial magazine, SAM publication, club newsletter, etc.  Entries with different qualifying models may be made in any event, but flights in one event may not be doubled up with any other class for which a given model is eligible  separate flights for each event, please.

The 20” Rubber class is to encourage the flying of all such models designed for outdoor use and not usually considered competitive against larger designs. There is no restriction on publication or production date and all designs published in/on freely available sources i.e. newsletters, websites, etc. are acceptable provided such source and/or details are available to others.

To maximize flying opportunities there is ample scope for a variety of rubber models and gliders to be flown in multiple events and you are encouraged to take stopwatch, pencil and notepad with you each time you go to your local field, or to a contest, as an added incentive to your flying enjoyment. If you make flights in another contest and wish to enter times in the WWP, it is best to record those flight times separately in a format which is consistent with WWP rules. Bear in mind, also, that any number of individual models may be flown in any event for which they are eligible.

A full report will be published here after the scores are received and compiled. To enhance the same, a brief account of weather, site, flying anecdotes, photographs, etc. would be appreciated when scores are submitted. Please ensure that all scores are posted here in Comments, under the Leave a Reply heading, below, by July 15th, 2018; earlier submissions would be most gratefully received! Please provide clear notice as to which class/event they should be posted to. Reporting scores all along should stimulate participation. Flyers who see scores posted better than theirs should take this as an indication that they can do better. Feel free to ask questions.

I welcome any comments regarding amendment to any event rules that might make same more attractive, or suggestions for other classes that might be considered of general interest in any future Contest.

  1. Gary,
    The OCD has three events to support the postal competition. They are 6” Catapult, 20” Rubber, and Sky Bunny. The contest held on 8/12/2017 had two entries in 6” Catapult and none in the other two.
    Those who entered 6” Catapult were Manuel Cisneros and me. By the time we started flying the wind was up and the contest was almost over. We each flew three flights.
    They were:
    Dick Douglas; 7 sec, 10 sec, 10 sec, for a total of 27 sec.
    Manuel Cisneros: 4 sec, 5 sec, 12 sec, for a total of 21 sec.

    The contest had great weather, calm and cool. It was poorly attended. It reminds me of a phrase in the late 60s that asked the question “What if they gave a war and nobody came?” oh, well, we’ll try again next year.
    Dick Douglas
