SEN Experiment

We are looking at adding optional  .ICS calendar downloads to SEN contest announcements so you would be able to download them and use them to update your personal calendar with contest dates.  We have one here as a trial for the two World Cup events at Lost Hills this October. So click here to down load calendar entries for this year’s endless October

Starter Discussions on FB

There has been an on going discussion on FB about efforts to promote events and series of events that appeal to beginners and those who do not wish to do the full F1ABC World Champs.  These events are based in Europe where international travel is a little simpler than in the rest of the world but they include some ideas that may be worth trying.

This is a Euro challenge for F1H gliders.  It has a number of sub classes , for example straight tow to promote the use of simpler models, they also specifically exclude all carbon wings and flappers. . The Rules are very comprehensive and too bulky to include here but you can go to their web site at :

There is also a Ero challenge for E-36/F1S. this event is a little simpler and does not have all variation of the F1H in the HEC because the F1S model is basically a simpler model.  So here are the rules. Thanks to Didier Chevenard for providing them

 The models used are either defined as in described in AMA E36 rules or FAI Sporting code F1S rules. Maximum span 36 inches 
minimum weight 120g 
2 S lipo battery max motor run 15s (E36) or 10 s (F1S) 
Flight duration 2mn 
No auto surface.
 Models for F1S and E36 being the same, contest will be run according to E36 rules (15s motor run) or F1S (10s motor run) on decision of the organizer. 
Given the efficiency observed on most power-trains, we encourage the 10s run to increase selectivity before fly-off. We also recommend to run the fly off with a 5s motor run. 

SCORING RULES For the final scoring the best FIVE results are taken into account, but in any case one competitor can count a maximum of THREE contests per country. These two limits are set as a compromise to cope with the problem of traveling and to give more chance to the modelers of the countries in which few contests are flown. In case of parity the sum of the points of the not counted events will be taken into account. 

Scoring system : For each considered event, a score is assigned basing on the competitor position and the number of participants such as follows : Number of participants is divided by two, if the total is odd is rounded by excess. That value represent the points assigned to the first placed. One point less is assigned time by time to the others up to two points. One point is then given to all the other competitors who flown at least one round. If participants are 25 or more the maximum score given start from 13 to the first regardless the total number of competitors. 

Examples : With 11 participants, 6 points are given to the first, 5 to the second, 4 to the third, 3 to the fourth, 2 to the fifth, 1 to all the others. 

With 30 participants, 13 points are given to the first, 12 to the second..........2 to the 12th and 1 to all the others. 

COUNTRY MANAGERS A Country manager is in charge of - Identifying the contests to be taken in the Eurochallenge (max 3) - Communicating to the countries coordinator the names of the potential contestants in order to have them copied of the schedule and results - capturing the final results in each of the contest and communicating them to the Coordinator. 
Final Eurochallenge results will be finalized for the month of October and celebrated at the last contest of the season (to be determined after collecting the contests identified.

F1G Euro Challenge

There is also a F1G Challenege created by Alessandro Manoni of Torino, we do not have rthe details of these events.

These 3 simple Euro series each have a final end of season event where the trophies are presented and the years flying celebrated. This is typically planned for October. The late season date sometimes falls foul of the weather.

I Liked this one … From: SEN 2337

From: Steve Helmick

I really liked the idea presented by George Voss, tho there are certainly some technical problems to sort, with radio frequencies and all that.
 My recollection was stopping the watch when we saw a cloud of fuel vapor from the flood-off. With prop brakes and timer reaction time being what it is, it seemed reasonable and fairly consistent across the group of timekeepers. I assume flood-offs and prop brakes are still used. I'd wonder if there would be a way to make the vapor cloud even more visible, perhaps with dye. Thermals, Steve O'Bat

Two comments to SEN 2337

From: per grunnet

Javier Abad writes about the F1A fly-off at the World Championships held in Livno in 1985, that the first fly-off for four minutes was cancelled, and all competitors had to make a new flight. This is not correct – all who had not maxed were allowed another attempt in a new four-minute fly-off. Those who maxed in the first fly-off went directly to the five-minute fly-off.
The first fly-off suffered from – at least – two faults: The Norwegian flier Svein Larsen had no time-keepers when the fly-off-round was started. And the fly-off was shot off two minutes earlier than announced.

Chris Edge writes about the 20 second-rule, that prevails in the FAI rules. It was actually cancelled some years back, but was brought back in the rules a couple of years later, which I - as Chris - find very strange. The Danish Aeroclub proposed to cancel the 20-second rule at the last CIAM-meeting in April this year, but the proposal was rejected.

ClariF1Cation from Dino

From: Michael Achterberg

Clarification. Sorry I wasn't saying run the engine on the ground although guess it read that way. What I meant to say was run the Etimer alone to verify setting. It takes way to much time to fill up bladder, setup model, start engine, etc to do that pole after pole. Easy to set timer up and run thru motor run function to verify timer setting. Every One seems concerned that someone might try to cheat and grab a couple tenths of seconds. Personally, I don't believe it. We are a small group of friends that have known each other for years to decades. Just don't see that as an issue. You only would cheat yourself. Hope this clarifies what I was trying to suggest.
