F1 Free Flight Rankings

Free Flight Ranking positions on May 1 2017

The purpose of the Free Flight Ranking is to demonstrate the relative merit of performances by competitors on a continued basis. Results are included from all Championships and World Cup events in each class.

The ranking score from an event consists of two components added together:

a) a results part with points awarded on the same basis as the World Cup

b) a ranking position component. This allocates points according to how well a competitor’s performance compares to others – points awarded if he has placed above higher-ranked competitors and points subtracted if he has been beaten by lower-ranked competitors.

The scores form events in the last 12 months are counted in full. Events between 12 and 24 months have scores reduced linearly so that events older than 24 months make no contribution to the ranking. A total of 6 events can be counted to make the competitor’s ranking score, except that all negative scores are counted.

The ranking is evaluated every 2 months. The results contributing to each competitor’s score are shown in the format XY15=nn+pp where XY is the abbreviation for the World Cup event or WC or EC or AC for World, European or Asian Championships, 15 indicates an event in 2015, nn shows the results points (a) and pp shows the ranking position points (b) which will be preceded by + or – sign.

More information

F1 - Free Flight - outdoor

Free Flight World Championships and many major competitions are flown with the following model classes:
F1A gliders - projected surface area 32-34 dm2, minimum weight 410g, towline 50m. Historically also known as A/2 Nordic gliders. The gliders are launched with 50m towlines, the tow hook allowing models to be flown in circles while searching for thermals during towing. The highest performance models are accelerated to high speed before release from the towline, resulting in a climb and bunt to an altitude 30 or 40m higher than the towline length.

F1B rubber power - projected surface area 17-19 dm2, minimum weight of model without motor 200g, maximum weight of rubber motor 30g. Also known as "Wakefields" after the prestigous trophy which is the award at the World Championships. Typical models have a wing span of 1.8m and climb to an altitude of at least 80m while the propeller running. The initial climb is vertical aided by a powerful launch, sometimes having the start of the propeller delayed until about a second after launch, becoming less steep before the propeller folds after about 40 seconds.

F1C power model - minimum loading 20 g/dm2, minimum total weight 300 g/cc, maximum volume of motor 2.5cc, maximum motor run 5 seconds. Typical models have a wing span of 2m and reach altitudes of well over 100m in the 5 seconds of climb.

The outline specifications are shown here, the full details are available in Volume F1 of the Sporting Code section 4.

These classes are flown to a maximum flight time of 3 minutes on each of 7 flights. Fly-off flights are flown to decide the final winner when there is a tie, with the maximum duration increasing by 2 minutes between each flyoff round.

  • F1P is a simpler power model is flown as the power class in Junior World Championships. These models have motors with maximum capacity 1cc, a maximum wingspan limit of 1.5m, minimum projected area 26 dm2, minimum weight 250g, maximum motor run 7 seconds. Maximum flight duration 3 minutes for all flights.
  • F1Q is a new class for electric powered models. The battery weight is limited to a maximum of 125g for NiCd or NiMH batteries or 90g for Li batteries. Motor run is limited up to a maximum of 25 seconds. For the flyoff to determine a tie the motor run is reduced by 5 seconds for each successive flyoff round. Maximum flight duration 3 minutes.

Smaller model classes are defined which have a lower performance and are flown in competitions with 5 flights and the shorter maximum flight times of 2 minutes. These are:

  • F1G rubber power - minimum weight of model without motor 70g, maximum weight of rubber motor 10g. Historically known as "Coupe d'Hiver".
  • F1H glider - maximum projected surface area 18 dm2, minimum weight 220g. Historically known A/1 gliders.
  • F1J power model - minimum weight 160g, maximum volume of motor 1 cc, maximum motor run 5 seconds. This class originated in the 1/2A power model class, for a while it was used as the power class in Junior Championships, but this has now been superseded by the larger slower models of the F1P class.
  • F1K carbon dioxide powered model - minimum weight 75g, maximum surface area 12 dm2, maximum volume of CO2 tank 2 cc

Another World Championship category of glider is F1E for slope soaring gliders. These models are steered into wind by an automatic system on the aircraft, usually a magnet linked to a rudder, and are flown for 5 flights with a maximum time of up to 5 minutes on each flight.

F1 - Free Flight - indoor

F1D-RichardsThe World Championships class F1D permits rubber motors of up to 0.6 gram in an aircraft with a minimum weight of 1.2g the without rubber motor. Dimensional limits are maximum wing span of 550mm, maximum chord of lifting surfaces 200mm, and maximum tail span 450mm. Models are usually made of a balsa frame covered with a lightweight transparent covering, either microfilm or plastic. Flights of up to 40 minutes are possible with F1D models.
There are two other rubber powered classes for smaller models:

  • F1L (also called EZB) with minimum weight without motor 1.2g, maximum wingspan 457.2mm, maximum wing chord 76.2mm and stabiliser area limited to 50% of wing area. There are limitations on the structural materials for the airframe and propeller.
  • F1M with minimum weight or airframe 3g, maximum motor weight 1.5g, and maximum wing span 460mm.

For all 3 rubber-powered classes competitors are allowed six official flights, from which the total of the best two count for the final classification. At the World Championships there is also an award for the longest single flight in the Championships.
A different type of indoor class is F1N for hand-launched gliders. In competitions for this class flyers are allowed 9 flights from which the total of best 3 times count for the final classification.

F1 - Free Flight

F1-FreeFlightFree Flight models are flown without any form of mechanical or radio control over the model in flight. This is the earliest form of aeromodelling, a particular milestone being the first model powered by a rubber band built and flown by Alphonse Penaud in 1871. Always present since that time has been the joy and achievement of releasing a model and seeing it soar overhead in its planned flight pattern.

Free Flight competitions are solely determined by the total flight duration achieved over a set number of flights, the stopwatch is the only judge of success. Competitors always strive to improve models by design and trim adjustments to achieve the longest flight time.

There are two fundamental categories of free flight model - indoor and outdoor - with various types and specifications in each category. These classes will now be described, with outline of main points of the rules (see Sporting Code for full specifications).

Most indoor models are powered by twisted rubber motors, with a maximum weight of rubber permitted in each class along with limitations on the airframe size and minimum weight. Championships are flown in large buildings, particularly airship hangars (old or new), exhibition halls, and also the salt mines in Romania. Smaller models or local competitions may be flown in local buildings such as sports halls. Rubber powered models have the motor driving the propeller during the entire flight, climbing up to close to the ceiling and then descending slowly during the rest of the flight as the torque of the motor reduces. The indoor classes recognised by FAI are the World Championships class F1D, two other rubber powered classes for smaller models F1L and F1M, and hand-launched gliders F1N.

Outdoor models are in 3 major forms - gliders, rubber powered, or powered by motors. Rubber models are powered by a twisted rubber motor driving a propeller which folds to leave the model to glide when the turns have unwound. Power models have a limited size of internal combustion motor or electric motor and this is allowed to run for a short time, after which the model glides. There are two types of glider, one launched by towing them up on a line 50m long and the other flown from hills with steering to keep them facing into wind.

Traditional models were constructed from balsa wood and covered with tissue paper, but for competition models this has largely been superseded by new technologies for making lighter stronger structures. Many models have airframes made mainly from carbon fibre and covered with plastic film. A common feature of all outdoor models is that they are subject to the wind and rising or descending air currents. Competitors work to understand the air motion and to keep their models up best by launching into thermals.

Major competitions are flown with the aim of flying for at least 3 minutes on each of 7 flights. Fly-off flights with increasing maxima are flown to decide the final winner when there is a tie. Clockwork or electronic timers are used to make pre-set adjustments to controls during the flight and to bring the aircraft down when the maximum time has been reached. Models are trimmed to circle during the gliding flight, which circles then drift downwind with the prevailing wind. Smaller models classes are defined which are flown to the shorter maximum time of 2 minutes.

The World Championships class for rubber powered models is the oldest type of aeromodelling international competition. The F1B World Champion is awarded the Wakefield Trophy, which has been competed for since 1928.

F1S Rules. The CIAM Plenary meeting 2015 approved the rules for F1S, which is an international designation and organisation for the E36 electric model class. The new rules are given here: F1S rules
