The French eXtreme Flight Championships (FXFC) is a European contest, where radio-controlled aircraft fly aerobatic routines set to music.
This document provides both general and specific rules and guidelines to be followed during the contest.
The rules and guidelines contained within this document were created by pilots, judges and organisers from previous FXFC contests. The information within this document is therefore designed for pilots, judges, organisers and members of the public who require information about the 2018 FXFC.
2.ENTRY REQUIREMENTS, INSURANCE REQUIREMENTS AND PILOT RESPONSIBILITIES
Each pilot must agree to respect the rules detailed within this document.
Each French pilot must be in possession of a valid, up-to-date federal license.
All other (non-French) pilots must be in possession of a valid, up-to-date federal license from their country of origin and a valid, up-to-date insurance certificate.
Each pilot can be accompanied by a maximum of 2 coaches. Each coach must be in possession of a valid, up-to-date federal license from their country of origin and an up-to-date, valid insurance certificate.
Each pilot’s model aircraft must meet the criteria outlined below:
It must be a scale representation of a real aircraft
It must have a minimum wingspan of 185 cm for monoplanes, or 160 cm for biplanes
If fitted with an internal combustion engine, the engine size must not be greater than 250 cm3
If fitted with an electric motor for, the maximum nominal voltage of the associated power source must not be greater 72 volts
The maximum take-off mass, with all equipment fitted for a flight (such as fireworks, special effects etc) , including any fuel or liquids such as smoke fluid, must be no greater than 25kg
Absolutely no gyroscopic stabilisation systems of any kind are permitted
No variable pitch propellers are permitted
Each pilot assumes full responsibility for their model aircraft and thus it is up to them to ensure their model aircraft is in good, airworthy condition and will not pose a safety hazard at any time.
The Contest Director can, at any time, remove a pilot from the competition who does not respect and abide by the rules detailed within this document.
3.REGISTRATION PROCEDURE AND CONTEST SCHEDULE
Each pilot must register via the FXFC website: www.fxfc.fr
The entry fee is 60 €, each pilot must use the Paypal link available on the FXFC website to pay this fee.
The total number of pilots is limited to 40, the organisers reserve the right to select which pilots will be selected for the contest, at their discretion, if the total number of registrations is larger than 40.
The FXFC is a 4-day long contest, which consists of 1 day for training and practice flights, 2 days of qualification rounds, and 1 day for the semi-final and final rounds. The breakdown is as follows:
Thursday morning: Training and practice flights
Thursday afternoon: Training and practice flights
Friday morning: 1st qualification round, each pilot to fly once
Friday afternoon: 2nd qualification round, each pilot to fly once
Saturday morning: 3rd qualification round, each pilot to fly once,
Saturday afternoon: 4th qualification round, each pilot to fly once
Sunday morning: Semi-final rounds, each pilot to fly twice
Sunday afternoon: Final round, each pilot to fly once, and the awards ceremony
The specific times each round will take place and further details is available on the FXFC website.
Before the beginning of the contest, the order pilots will fly in, will be drawn for the qualification rounds. For the semi-final and final rounds, the flying order will be re-drawn.
For following flights, the shooting order is shifted from ¼ of total number of pilots and from ½ for semi-final flights.
After every 10 flights, a 10-minute break will take place. During this break, sponsor of the FXFC contest can carry out demonstration and promotional flights.
For each flight, each pilot will present their aeromusical program to the judges.
Following the flight, each judge will complete a sheet with 6 distinct criteria, against which the pilot is scored.
Each criterion is multiplied by a numerical factor to obtain a total score from each judge for the flight. The scores of all judges are added together to arrive at a final score for the pilot’s flight.
Upon the completion of a round, the scores of all pilots will be normalised, such that the highest scoring pilot will have a score of 1000.
After all 4 qualification rounds have taken place, for each pilot their two highest scores (after normalisation) will be added together to arrive at their score for the entire qualification stages. The top 20 scoring pilots will then proceed to the semi-final round. In the event of two or more pilots scoring the same, the highest scoring pilot will be the one who has the highest total from all 4 qualification rounds, and so on.
After both semi-final rounds, each pilot will be scored based on their highest scoring flight (after normalisation), the top 10 pilots will proceed into the final round. In the event of two or more pilots scoring the same, the highest scoring pilot will be the one who has the highest total from the 2 semi-final rounds, and so on.
After the final, the final standings will be determined by scores after normalisation. In the event of two or more pilots scoring the same, the highest scoring pilot will be the one who has the highest total from the final round and the 2 semi-final rounds, and so on.
4.FLIGHT RULES AND SAFETY RULES
Each flight will be flown to music.
The pilot can choose to perform either of 2 aeromusical programs that they have prepared in advance.
There is no restriction on the content of the music, nor on the aerobatic manoeuvres that can be performed.
Each pilot has a maximum time limit of 1 minute to start their aircraft’s propulsion system. In event of a technical issue that prevents this, the pilot who is next scheduled to fly, will immediately take the current competitors place. The opportunity for the pilot who was unable to start their aircraft, to try to fly again at the end of the round, will be left to discretion of the organisers.
The duration of music shall be 4 minutes ±10s.The total flight time from the moment the wheels leave the ground, to the moment they touch the ground after the completion of a competitive flight shall be no longer than 6 minutes.
If the total flight time is over 6 minutes, the pilot will score zero for that flight.
If the pilot was unable to complete their flight (due to crashing etc), the pilot will score zero for that flight. If the pilot was unable to complete their flight due to reasons beyond their control, i.e. some external disturbance such as the sudden onset of heavy rain, then they will be permitted to re-attempt their flight at the discretion of the organisers.
The signal to begin playing music for a flight, will be the up-and-down motion of the pilot’s arm or their coach.
The duration of music time and the total flight time will be checked by a responsible person chosen by the organisers.
For safety reasons, the pilot must completely shut down the propulsion system of their aircraft the moment it has landed. If this does not take place the pilot will score zero for that flight.
The security line is the internal edge of the runway. The pilot shall stand on this line (see the following diagram). If the aircraft crosses this line at any point during a flight.
If at any point during a flight, any part of the aircraft touches the ground, including touch-and-goes, the pilot will score zero for that flight and must land their aircraft immediately.
Any visible part of an aircraft breaking away/off from that aircraft during a flight, will be a safety hazard and the pilot will score zero for that flight and must land their aircraft immediately. The obvious exception to this is the use of special effects, such as confetti, banners etc. If you are unsure whether your special effect will violate this rule, please contact the organisers.
In the event of any other visible safety issue with an aircraft the pilot will score zero for that flight and must land their aircraft immediately.
Any dangerous high-speed manoeuvres at low altitude close to the judges and spectators may lead to a reduction in a pilots score for that flight.
During a flight, the pilot must keep their model aircraft under their full control at all times, if a situation arises where the pilot must make a decision between the safety of their model aircraft and the safety of themselves, judges, spectators or any person nearby, then the pilot will be expected to choose to safely crash their model away from these people.
The judges will be located at a distance of at least 25 metres behind the pilot.
Here the various scoring criteria and associated K-factors are detailed:
1. Originality and difficulty of the program (k = 20)
This criterion is a measure of both how original the program is, and how difficult it is to fly well. Excessive repetition of manoeuvres is discouraged, whereas new manoeuvres are favourable.
2. Use of the total flight space (k = 20)
Ideally, a pilot will make full use of the flight space available. For example, flying only to the right-hand side or only far away will score poorly. How safely the aircraft has been flown is also reflected in this criterion.
3. Preciseness and quality of the manoeuvres (k = 20)
The overall precision of execution and quality of manoeuvres are evaluated. For example, how accurately and crisply point-rolls stop and the clean exits of spins, and the general impression of how settled and stable the aircraft is throughout the flight.
4. Use of special effects (k = 10)
The use of special effects to enhance the impression of the flight is evaluated. These special effects should be used in conjunction with a manoeuvre for best effect, for example, the use of tip smoke during a spin. If a special effect is used for a long period of time without any directed purpose or focused use, then the pilot will score poorly for this criterion.
5. Harmony with the music (k = 40)
How well the flight is harmonised with the music is evaluated. The rhythm and dynamics of the flight are expected to broadly match the music being played. For example, high-tempo flying with high-tempo music. Furthermore, how well the flight is executed during transitions between different pieces of music is also taken into account.
6. Overall impression (k = 30)
The overall impression the flight gives is scored under this criterion, this is a measure of how the flight comes across as a cohesive whole.
The following bullet points outline the expected content and discussion points of the contest briefing:
Introduction of the director of the contest, the safety manager, and the judges
Time schedule for the contest
The boundaries of the flight space, the security line, pilot location during flight, procedures for the administration of music
A reminder of the various ways a flight can be scored zero:
A loss of part of the aeroplane during flight (with the exception of special effects)
The flight was too long
The aircraft comes into contact with the ground
Crossing of safety line
Some other visible issue with the aircraft
Failure to cut the engine immediately after landing
General unsafe flying
A reminder that high-speed and low altitude manoeuvres close to the judges may lead to a reduction in scores
A reminder of the time available to start the aircraft (1min), the total flight time available (6min) and the permitted length of the music (4min+/-10s)

7.MP3 FILE FOR MUSIC
Each musical file must be provided in .mp3 format. The duration of the music must be 4min +/- 10s.
If you provide only one piece of music, the name of the file must follow the format:
FXFC-<your first name>-<your surname>.mp3
If you provide two pieces of music, one must be named:
FXFC-<your first name>-<your surname>-program-A.mp3
And the other:
FXFC-<your first name>-<your surname>-program-B.mp3
For example, a pilot named Shahid Banglawala enters the contest with two pieces of music, his filenames shall be:
Pilots must respect the deadline for submission of .mp3 files indicated on the FXFC website.
It is advised that pilots equalise their .mp3 files for good quality.
The use of pyrotechnic special effects (with the exception of Bengal Lights), and biodegradable confetti and banners, is allowed.
Any pyrotechnic special effects must be fixed to the aircraft with a robust metal fixing.
Each pilot must be committed to read and respect the rules detailed within this document.
Before the beginning of the contest:
The organisers will print and make available to the pilots the below form
Each pilot must complete and sign a row of the form
