The maximum points to be awarded (vertical Axis) plotted as a function of the time achieved above the target value of 60 seconds (horizontal axis).
(a) For a race with 5 contestants and:
• The winner gets an average time of 59.4. He is awarded the maximum of
10 points as he is in the top band.
• The 2nd place time is 62.7. He is awarded the max points for that band 7
• The 3rd place time is 62.9. He is also in the band which has a max points
of 7 awardable and so he is awarded the next available score which is 6
• The 4th place gets a time of 64.8 which has a band max of 6, but this has already been awarded, so he gets next available highest score of 5 etc.
• The 5th place time is 93.0. He is in the band of Max = 0 so gets zero
(b) For a race with 2 pilots :-
• The winner gets a time of 66.1, so gets 5 points.
• The 2nd placed gets time of 72.2, so gets 2 points.
5.3.4 BMFA Variations on F5D Pylon Racing
The F5D class rules can be downloaded at https://www.fai.org/page/ciam-code or obtained direct from BMFA Head Office.
184.108.40.206 Starting Procedure
F5D will adopt the same starting procedures as the host classes. The timing of the models will start at the drop of the starter’s flag or the signal given by the electronic race program (not when the model reaches the start line after a run up period). Launching out the back of the course is specifically prohibited in the interests of safety.
220.127.116.11 Nomination of Contest Director
A member of the F5D fraternity will be nominated as the class CD at the start of every meeting, including the BMFA Nationals. He/she will be the sole point of contact between the competition organisers and the F5D competitors and will also determine what level of scrutineering will take place, if any.
18.104.22.168 Weighing of Models
Any scales made available for competitors to check the weight of their models will be considered as being the “scales of the day”. The scales supplied will not always be the same set and for that reason they will not necessarily be calibrated. The scales will be made available throughout the period of the competition and it is the competitor’s responsibility to ensure that his model complies with the manufacturer’s maximum all up weight. In the event of any dispute regarding the weight, wing loading or dimensions of any model, the manufacturer’s figures will be considered as fact.
5.3.5 F5D Team Selection
(a) Selection for a World or European Championship team will be made in the year preceding the Championship.
(b) Team Selection will be based on an individual’s cumulative scores from BMPRA sanctioned league competitions held during the qualification year.
(c) The score for each competition is calculated as per F5D league scoring. The best scores from the eligible competitions to count are added together to get a total team selection score. These scores are ranked and the top three competitors are offered a place on the team.
(d) If any of those qualifying do not wish to be a team member, the place or places will be offered to other competitors in order of the team selection score ranking, i.e 4th place in is 1st reserve for the team.
(e) The number of competitions to count for team selection is as follows:
4 competitions from 7 or more eligible competitions to count
4 competitions from 6 eligible competitions to count
3 competitions from 5 eligible competitions to count
3 competitions from 4 eligible competitions to count
3 or fewer competitions flown, all rounds to count
(f) Selected team members may nominate one “Caller” to be included as part of the Championships team. The “Caller” is an official member of the team and therefore must also hold a valid FAI Sporting License for the year of the Championship and should commit to attending the relevant Championships as a team member.
(g) The selected team is submitted to the BMFA by the appropriate Specialist Body, currently the BMPRA.
5.3.6 F5D League Scoring
(a) For each competition the winning competitor will be the one with the lowest cumulative time for the counting heats from the day’s competition.
(b) The winner of the league will be the individual with the lowest total time, with a maximum of five rounds counting towards the total. The team will consist of the three pilots gaining the lowest total time for the required number of qualifying rounds as stated at clause (E) stated above.
No team member will be selected if they have not competed in any rounds..

(e) A minimum of one pylon judge per pylon will be employed to report any pylon infringements at Nos 2 and 3 pylons.
126.96.36.199 Mid-Air Collisions
In the event of a mid-air collision all models in that heat are to land immediately. All participants involved will have a re-fly that will take place at the end of the round in which the collision took place. A maximum of 10 minutes will be allowed for preparation time to allow competitors to prepare a spare model for the re-fly.
188.8.131.52 Starting Procedure
The race will consist of a maximum of four competitors and will be of 10 laps distance. Following the identification process a two-minute readiness time will be allowed on the start line to prepare the model for flight. The starter will signal the start of the race with the drop of a flag whereby all models in that heat will be launched simultaneously. No model is to be launched after the leading model has completed the first lap. Should any model crash or not get away it is not to be retrieved until the end of the race. Pilots and callers must stand behind the start line at all times during the race.
(a) A timekeeper, equipped with a stopwatch will be allocated to each competitor during the model identification process.
(b) The model is to be launched from behind the start line. Any model deemed to have been launched prematurely or forward of the start line will be subject to a 10% time penalty (which will count as 1 cut) being added to the total time.
(c) Any pilot causing his model to cut inside a pylon will have a 10% time penalty added to his time. Two cuts in the same heat will result in that pilot being disqualified from that heat. Should any dispute arise regarding lap timing / counting or flagging errors the Competition Director’s (CD) decision will be final.
184.108.40.206 Dangerous Flying
Low flying is consistent flying below pylon height. The CD may issue a warning for low flying, if the competitor continues to fly low, in subsequent heats, the CD reserves the right to disqualify the perpetrator from that heat or the meeting.
220.127.116.11 Model Processing
(a) The CD reserves the right to check, or have checked, all models for all aspects of compliance with these regulations. Any model found to be outside the rules will be disqualified. Any competitor who has raced a model that has subsequently been
checked and found to be outside the rules will be excluded from that heat.
(b) The offence of exclusion will carry the application of a maximum time penalty. Any heat from which a competitor has been excluded cannot count as a dropped score and will count towards the final score.
18.104.22.168 Protective Clothing
All competitors, helpers, timekeepers, flag marshals and race officials are to wear hard hats at all times whilst racing is in progress.
22.214.171.124 Number of Heats Flown
To account for weather conditions and other possible interruptions to the race day programme the number of heats that will count towards final scores will be as following:
The pilot with the lowest total time from the number of heats flown will be deemed to be the winner of the competition. If numbers and time permits two semi finals and a final will be flown to decide the top eight positions. League points will be awarded in descending order from 8 down to 1 for the top eight competitors.

220.127.116.11 Race Course and Procedure
(a) The course size is 40 metres between base pylons and 115.75 metres measured down the course centre line from the base pylons to number 1 pylon. The start line must be 18 metres from the base pylons. Three launching positions must be marked at 4.5 metre intervals along the start line, to the right of the course centre line if possible.
(b) The pylons should be a minimum of 4.5 metres high, surmounted by a
500 mm x 500 mm (min) square flag. The top of the No. 1 pylon should be above the horizon if possible.
(c) The course layout is a long triangle and should be set if possible with the wind blowing from No. 1 pylon towards the base pylons. The course will be flown in an anti-clockwise direction. It is the responsibility of the Contest Director (CD) to ensure the accurate positioning of the course and pylon marshals. Principally this should be in line with FAI guidelines which can be found at https://www.fai.org/page/ciam-code
18.104.22.168 Pylon Judging:
(a) All competitors are required to fly around each pylon, therefore, pylon judges and flag men are to ensure a complete circuit is made.
(b) If a model hits any part of a pylon, excluding the flag, then a cut will be awarded and the race will be stopped for inspection of the model and pylon. The cut will stand for any subsequent re-fly.
(c) No. 1 pylon flag men are to ensure that the model has passed the pylon, before dropping their flags. Once a No. 1 flag man has dropped his flag, he may not award a cut under any circumstances.
(d) Time keepers will be situated in a straight line facing No 3 pylon, the race time will be taken from the drop of the Starter's flag, until the tenth lap, when the model is inline and passing No. 3 pylon. A competitor cutting a pylon (flying inside), will have ten percent of the 10 laps time added to his overall time.
(e) A launcher and model, must be behind the start line when the flag drops for the
start of the race, otherwise one cut will be awarded against the competitor. If a launcher is judged to have launched the model before the Starter drops the flag, then one cut will be awarded against the competitor. Two cuts in any race, will cause the competitor to be disqualified from that race.
(f) When an officially acknowledged timing, flagging or any administrative error takes place, only the competitor directly involved will be given a re-fly. Where a dispute exists on lap counting, flagging or timing errors, the Competition Director’s decision is final. If the Competition Director is flying in a particular round, he must delegate his responsibilities whilst flying that round.
22.214.171.124 Start Positions:
(a) Normally, a competition matrix will ensure that competitors will rotate along the start line positions throughout the competition rounds. The qualifiers in each semi-final or final will choose their own positions on the start line, accordingly to their qualifying times, ie: the fastest qualifier has first choice, second qualifier second choice and third qualifier takes the remaining position.
(b) The competitors will identify their models to the pylon judges, switch on their radios and check correct operation of their models when told to do so by the Starter.
126.96.36.199 Starting Procedure:
(a) The race will consist of a maximum of three competitors flying 10 laps of the course. Models will be hand launched from behind the start line. 30 seconds will be allowed for starting engines.
(b) The models will be launched at one second intervals except finals where there will be a simultaneous start. Timing will commence upon the drop of the model’s flag regardless of whether the model is launched at that precise moment.
(c) For safety reasons, models must not be launched after the first model has crossed the downwind leg of the start/finish line.
(d) Competitors may only retrieve their models after the race has finished and all models have landed.
(e) Competitors and their callers must stand behind the start line at all times.
(f) Models may only be flown between the base pylons on landing by permission of the Starter.
188.8.131.52 Mid-air Collisions:
(a) In the event of a mid-air collision all models in that race must land immediately for inspection. All competitors in that race will have a re-fly which will take place at the end of the round in which the mid-air occurred. Any cuts awarded prior to the midair will stand for the subsequent re-fly.
BMFA R/C Power Rules 33 Effective January 2020
(b) If a competitor suspects a mid-air collision, he should notify the Starter and pull out if instructed to do so. The model will be inspected immediately on landing and if found to be damaged as a result of the mid-air then a re-fly will be awarded.
(c) If the mid-air collision occurs after one competitor has completed 10 laps, then his finishing time/position shall stand. If this situation arises in a semi-final, or final,those competitors involved in the mid-air shall be deemed to have finished behind the one who completed the race and there shall be a “fly off” for the remaining places.
(d) At the CD’s discretion, a competitor may be allowed a trimming/check flight to ensure the safe flying characteristics of a model that has been subject to a mid-air or which has not been used during the competition. Such check-flying shall not take place until the course has been erected and the CD has granted permission.
184.108.40.206 Dangerous Flying:
Low flying is consistent flying below pylon flag height, which endangers all concerned. The CD may give a competitor a warning for low flying and if the competitor continues to fly low, the CD shall disqualify him from that heat. The initial warning counts for all the following heats, semi- finals and finals. At the CD’s discretion, a competitor may be disqualified from the heat or the competition, if it is adjudged that he is flying dangerously.
220.127.116.11 Engine Checking:
The CD may randomly select (by lottery) one of the semi-finalists who must remove the cylinder head and liner for inspection by two selected examiners. The CD may also request that any engine that has raced on the day, be selected by the examiners for full scrutiny.
18.104.22.168 Model Checking:
The CD may request that any model that is to be flown in the semi-finals and finals, be checked for conformance to the technical regulations prior to those races.
22.214.171.124 Qualifying Times:
(a) Number of heats flown Number of heats counting
(b) No times, Did Not Start (DNF) and Did Not Finish (DNF) will be awarded a time of 200 seconds.
126.96.36.199 Finals Start Sequence:
For the finals only, all models will be launched at the drop of one start flag or indicator.
BMFA R/C Power Rules 34 Effective January 2020
(a) Protective headgear must be worn at all times by all personnel in the flying area.
(b) No competitor may fly any model that has previously been flown by another competitor at the same competition.
(c) Ties in finals will be decided by taking the better semi-final time. If a tie still exists then the fastest single heat time will determine the winner.
(d) Any leagues will be determined by awarding 10 points for the competition winner, 9 for second and so on. According to the number of competitions flown, then competitors’ league scores will be determined on the same drop out basis as the semi-final qualifying times. Ties in the league will be broken by taking the fastest
time of the league. If the tie still exists then the second fastest time will be taken and so on until the tie is broken.
188.8.131.52 Interpretation of the rules:
Any interpretation of these rules will be at the discretion of the BMPRA Committee, whose decision will be final notwithstanding a competitor’s right to protest (see 5.0.6).
