Since 1979 the Great Britain R/C Aerobatic Association (gbrcaa.org) has been a specialist body of the British Model Flying Association looking after the organisation and development in the UK of F3A and in addition and more recently F3P indoor electric precision aerobatic model flying.

 

In the early days it was the likes of Geoff (it’s only a bit of fun matey) Franklin and Kath (former chairman of the BMFA) and Terry Watson with some friends in the Leicester area brought together the aerobatic flyers and formed what we now know as the GBR/CAA. 

 

Today we have a full programme of events but follow the Sporting Code of the Fédération Aéronautique Internationale, (fai.org) the World Air Sports Federation which was founded in 1905 and has its headquarters in Lucerne, Switzerland.

 

F3A models have to weigh under 5 kg and fit into a two metre square box.  The aerobatic sequence of manoeuvres has to be completed in eight minutes and is flown at the highest level with specially designed 2 metre models powered either with an electric motor of about 3 kilowatt power, or the YS four stroke.  Some electric power models have a direct drive to the propeller whilst others have a gearbox with around 6.7 to 1 reduction ratio with the power being provided by a 10 cell (37 volt) lithium polymer battery of around 5 amp hour capacity.  These cells weigh around 1200 grams and are designed to give just sufficient energy to complete the eight minute schedule. The very successful ‘YS’ 28/30cc four stroke, super charged, direct fuel injection internal combustion engines, some running with spark ignition, are still used by some, including the 7 times World Champion Christophe Paysant-Le Roux from France.

 

We organise precision aerobatic competitions around the country on most weekends from April to October.

 

F3P electric indoor models have a wingspan of about 850mm and weigh around 90 to 125 grams and are made from depron strengthened with carbon strip, rod or tube.  Pilots compete in our winter league for promotion, or to become a member of the United Kingdom team, much the same as F3A pilots do.

 

For your £20 annual membership the GBR/CAA provide the infrastructure to compete at your own level of ability. We have five F3A schedules called Clubman, Intermediate, Advanced, Masters and FAI and three indoor schedules ‘A’ ‘B’ and ‘C’.  The F3A Clubman and Intermediate schedules are illustrated lower down, but all our schedules are available on our web site at gbrcaa.org, along with our contest calendar, photographs of all our events and our forum.

Our leagues give progressive difficulty to pilots wanting to practice and compete for promotion.  Through the day of the competition, up to 20 pilots each get three opportunities (5 or 6 opportunities for F3P competitors) to complete the perfect schedule in front of two or more judges who score each manoeuvre out of ten to find the winner of the competition and points are awarded to update our league tables. 

 

Flying in F3A or F3P aerobatic competitions are a step forward for many club flyers to give some structure to their flying. We try to encourage any pilot to come and fly with us providing they have a BMFA ‘B’ proficiency certificate (or equivalent and suitable insurance). For most pilots the ‘competition’ consists of no more than trying to improve on their own scores from the last competition.  For the pilots who are prepared to put in the practice and fly at the top level we organise a series of four BMFA team selection events to pick the Team to represent the United Kingdom at European and World Championships held in alternate years. At this level members will have been campaigning for a team place for many years, probably flying 500 to 700 practice schedules a year before they qualify to be a team member.   Matt Hoyland, Kevin Caton and Steve Underwood with Team Manager, Ashley Hoyland competed in the World Championships in South Africa 2013.  The European Championships will be held in Liechtenstein in 2014 and the World Championships in 2015 will be held in Switzerland.

 

If you are a club flyer and wish to improve your flying come and join us.  The concept that huge amounts of money have to be spent on a F3A aircraft to compete is not true.  We always encourage new pilots to the competition scene to use the model they are flying at their club, providing it is under 7 kilograms and is capable of doing loops and rolls.

Our schedules to introduce a new pilot to F3A aerobatics are the Clubman and Intermediate schedules listed below, which lead onto the Advanced and Masters schedules then onto the FAI schedules which are changed every two years.  The P13 and F13 schedules are flown throughout 2012 and 2013.  The P15 and F15 are flown throughout 2014 and 2015 and so on.  The top schedules flown all over the world are issued by the Federation Aeronautic International (FAI) and are also on our web site at gbrcaa.org.

If you want something more difficult have a look at the FAI Preliminary and Finals schedule at: http://www.gbrcaa.org/acrobatfiles/P-13%20Call%20Card.pdf  ,all the judging notes and manoeuvre descriptions are there too.

 

The schedules are flown along a line 150/175 metres out from the pilot, within a 120° box, (60° each side of the centre line).  At least two judges award points out of ten for each manoeuvre and the points are multiplied by the difficulty (K) factor to give a score for the manoeuvre, these are totalled to give a score for the flight and averaged for the judges, the best two rounds of three decide the competition winner for each schedule.  Central manoeuvres should be centred on the centre line of the box and turnaround (end) manoeuvres should be within the 60° box each side of the pilot.  Lines should be level and straight, loops should be round, and all arcs within the manoeuvre of the same radii. Wings should always be level on entry and exit to rolls and spins, indeed all manoeuvres should hit the intended line of flight without hesitation. Use of throttle through a manoeuvre is as important as any other control input.  As you progress through the schedules, rudder should be used for wind correction.  On the ribbon diagrams above try deciding which rudder you would apply to compensate for a cross wind blowing straight out in any of the above manoeuvres.
