California FAI Tradition
Earlier this year you will have read in SEN long time SCAT member, Juan Livotto’s announcement that he was retiring from running the California FAI Invitational contest, usually known to all of us as “The Livotto”, after 40 years. This contest had been a fixture on the California free flight calendar and a “must” because of the excellent organization and weather.
As expected there has been much discussion on how to fill this gap in our calendar. Well known California F1A sportsman and this year’s USA Team manager in Mongolia, Brian Van Nest will continuing the California FAI tradition. Brian will run the event on the same weekend as this year’s Sierra Cup giving us 2 stellar FAI events together at Lost Hills on the same Columbus Day weekend. This year only the Sierra Cup will be a World Cup event. Both of course are America’s Cup events. Brian will be working with another NAC to host one of their World Cup events next year. Full details of both this event and the Sierra Cup will be given in the event flyers. The event has been renamed the California FAI, removing the word Invitational, because some of our international visitors, and locals too, were confused and thought a special invitation was needed to attend. Not so of course, everyone is very welcome.
For those of you looking to do a West Coast swing in the Fall/Autumn, Bill Booth’s SW FAI Contest on El Dorado Dry Lake at Boulder City, Nevada will be on 24 October, starting one day after the SAM Champs finishes at the same site. Bill’s information will be out shortly.

Virtues of Flyoffs-in-Shifts
5-round contests were approved by CIAM because Europeans and most other foreign fliers retrieve in foot. In contrast, most contests in the States retrieval is mechanized (motor cycles, golf carts, cars and occasionally mountain bikes). No wonder why we love 7-round contests. In fact the new FAI rules allow this provided the 7 round format is announced in advance.
More rounds tend to reduce the flyoff size. Suppose that on average 10% of the fliers drop each round with a standard max and 15% drop an extended 4 minute max. Then in a standard 7 round 3-minute max contest 47.8% of the fliers would finish clean (0.9^7). In a 5 round contest with two extended maxes 52.7% would reach the flyoffs (0.85^2)*(0.9^3). But the difference is not that dramatic.
Big flyoffs are very expensive in terms of timers (3 per flier in a word championship). The flight line can be very long, varying in height and downwind topography and visibility. But the main problem is having too many model simultaneously in the air, increasing the likelihood of timing errors (loosing models, model switching, timing the wrong model). (During the regular rounds the number of models in the air can’t exceed half when we time each other, a third if a flier has to be timed by two others like in Scandinavia, and a quarter in a pole system with four fliers.)
In practice, most flyoffs in the States are timed by a single timer. CIAM’s alternative to large flyoffs is holding them in two shifts. And once the number of clean fliers becomes manageable, switching back to a single flyoff.
The major argument against flyoffs-in-shifts is that they are unfair. But fairness is an ex-ante concept (before the fact), not an ex-post one (based on the outcome). In an evening flyoff, the temperature in the first shift might be higher with better visibility. But the second shift has better knowledge on the exact weather conditions if flown immediately afterwards.
We, in the States, should mandate that all flyoffs be timed by two timers per flier. For a flyoff-in-shifts the organizers should require that each flier time the alternative shift before chasing their model for their time to become official. The flight lines are shorter and the potential number of models in the air is halved. Personally, I would always prefer two timers in a flyoff-in-shifts, relative to flying together and being timed by a single timer.
Finally, every flier would love to be in the flyoff, even though only half or less manage to qualify. Flyoffs are an integral part of a contest with all eyes watching; a chance to fly with the best. CDs’ goal should not be to reduce the number reaching the flyoffs, but to have flyoffs better timed, including when held in shifts.

Our/Your/My ? Direction??
From: John Barker
I am a lifelong modeller who has not flown an International class since they
were ‘Wakefield’ and ‘Nordic’. I know in the minds of many that takes away
my rights of comment on F1 matters. However F! gives me a lot of vicarious
pleasure and I hate to see it, despite the recent successful Championships,
in such a muddle about the future.
The attraction of the international classes has been the improvements,
decade by decade, to meet the competition requirements. Unfortunately recent
improvements have been more and more in the hands of a few specialist, and
at a price. In addition the developments have reached a level where there
are few flying sites where good competitions can be held.
It is interesting that the International classes are now most like the
Vintage classes. The same old models appearing time after time and with
performances so similar that it is the thermal picking that wins the
competitions.
Here is a subversive thought. Are the FAI the best body to write rules for
your country?
To suit the creative urge in model flyers I think we need at least one rule
making body that changes the rules, say, every four years. Perhaps
biplanes, payload, pushers, canards to get the creative juices flowing. The
FAI had about 60 years changing only a few grams, a few metres and a few
seconds and I don’t think it has got to a happy place. The future is in
your hands not theirs.
Whilst I have the lectern, and not really connected to the above, except as
a part of F1. Instead of fiddling with Rounds would it be useful to
consider what the rest of the sporting world does when there are a large
number of competitors, that is to run heats.
This reduces the number of timekeepers needed right from the start. It
gives more fun with several minor competitions building to a great climax.
I have not thought of this in great detail. I can see that choosing the
competitors for the first heats would need some thought but perhaps that
would be an interesting choice for the country managers.
