Radio Control Soaring Model Aircraft
CLASS F3F - RADIO CONTROL SLOPE SOARING
Definition: This contest is a speed event for radio
controlled slope gliders. A minimum of four rounds must be flown. The
organiser shall run as many rounds as the conditions and time permits.
Characteristics of Radio Controlled Slope Gliders
Maximum surface area ..................................... 150 dm2
Maximum flying mass . ....................................... 5 kg
less than 75 g/dm2
Minimum radius of fuselage nose 7.5 mm in all orientations (see
The radio shall be able to operate simultaneously with other equipment
at the normally usedspacing in the allocated R/C bands (i.e. 35 MHz :
The competitor may use three models in the contest. The competitor may
combine the parts of the models between the rounds provided the
resulting model used for flight conforms to the rules and that the
parts have been checked before the start of the contest. Addition of
ballast (which must be located internally in the model) and/or change
of angles of setting are allowed. Variation of geometry or area is
allowed only if it is actuated at distance by radio control.
Any technological device used to aid in supplying data of the airís
condition or direct feedback of the modelís flight status is prohibited
during the flight. These devices include any transmission or receiving
devices not used to directly control the model aircraft (telephones,
walkie-talkies, telemetry of airspeed and altitude etc), temperature
detecting devices (thermal imaging cameras, thermometers etc), optical
aids (such as binoculars, telescopes etc), and distance/altitude
measuring devices (GPS, laser range finders etc). Telemetry of signal
strength at the aircraft receiver and state of the receiver battery is
permitted. Use of corrective eyeglasses and sunglasses are permitted.
If an infringement of this rule occurs, the pilot will be disqualified
from the contest.
Competitor and Helpers: The competitor must operate his
radio equipment personally. Each competitor is permitted one helper.
The helper is only to assist and advise the competitor until the model
is passing Base A for the first time and after the timed flight is
Definition of an Attempt: There is an attempt when the
model has left the hands of the competitor or his helper.
of Attempts: The competitor has one attempt on each
flight. An attempt can be repeated if:
The re-flight shall happen as soon as possible considering the local
conditions and the radio frequencies. If possible, the model aircraft
can stay airborne and has to be brought to launching height, launching
speed and launching position before the new 30 second period is started
by the judge.
- the launching attempt is impeded, hindered or
aborted by circumstances beyond the control of the competitor, duly
witnessed by the official judges;
- his model collides with another model in flight
or other impediment and the competitor is not to blame on that account;
- the flight was not judged by the fault of the
- the model (ie the fuselage nose) fails to pass
above a horizontal plane, level with thestarting area, within five
seconds of exiting the course, due to circumstances beyond thecontrol
of the competitor, duly witnessed by the official judges.
Cancellation of a Flight: A flight is official when an
attempt is carried out, whatever result is obtained.
A flight is official but gets a zero score if:
Organisation of Starts: The flights are to be performed
round by round. The starting order is settled by draw in accordance
with the radio frequencies used.
- the competitor used a model not conforming to
- the model loses any part while airborne;
- the helper advises the competitor during the
- the model is controlled by anyone other than
- the flight is not carried through;
- the model lands outside the assigned landing
- the model is not launched within 30 seconds
from the moment the starting order is given.
- any part of the model aircraft fails to pass
above a horizontal plane, level with the starting area, within five
seconds of exiting the course.
The competitor is entitled to three minutes of preparation time from
the moment he is called to the ready box. After the three minutes has
elapsed, the starter may give the order to start. After the starter has
given the order to start, the competitor or his helper is to launch the
model within 30 seconds. The competitor or his helper is to launch the
model by hand from the starting area indicated by the organiser.
If possible, the starting area, including the audio system, shall be
situated in the middle of the course (equal distance from Base A and
The time from launch to the moment the model enters the speed course
must not exceed thirty seconds.
If the model has not entered the speed course (i.e. first crossing of
Base A in the direction of Base B) within the thirty seconds, the
flight time will commence the moment the thirty seconds expires. If the
model has not entered the speed course within the thirty seconds, this
is to be announced bythe judges.
Flying Task: The flying task is to fly 10 legs on a closed
speed course of 100 metres in the shortest possible time from the
moment the model first crosses Base A in the direction of Base B. If
some irremovable obstacles do not allow 100 metres the course may be
shorter but not less then 80 metres. This exception does not apply for
world or continental championships.
Speed Course: The speed course is laid out along the edge
of the slope and is marked at both ends with two clearly visible flags.
The organiser must ensure that the two turning planes are mutually
parallel and perpendicular to the slope.
Depending on the circumstances, the two planes are marked respectively
Base A and Base B.
Base A is the official starting plane. At Base A and Base B, an
Official announces the passing of the model (ie any part of the model
aircraft) with a sound signal when the model is flying out of the speed
course. Furthermore, in the case of Base A, a signal announces the
first time the model is crossing Base A in the direction of Base B.
Safety: The organiser must clearly mark a safety line
representing a vertical plane which separates the speed course from the
area where judges, other officials, competitors and spectators stay.
Crossing the safety line by any part of the model aircraft during the
measured flight will be penalised by 100 points subtracted from the sum
after conversion, the penalty not being discarded with the result of
the round. The organiser must appoint one judge to observe, using an
optical sighting device, any crossing of the safety line.
Judging: The flights are judged by two judges who do not
have to be the same for all competitors.
The judges' task is to control that the flights are performed according
to the rules, to be time keepers and to ensure that the right distance
Scoring: The result of the flight is stated as the time in
seconds and hundredths of seconds obtained by each competitor. For the
purpose of calculating the result of the round, the competitor's result
is converted this way:
1000 x Pw/P
where Pw is the best result in the round and P is the competitorís
Classification: The sum of the competitor's round scores
will determine his position in the final classification. If more than
three rounds were flown the lowest round score of each competitor will
be discarded and the others added to obtain the final score which will
determine his position in the final classification. If more than
fourteen rounds were flown, the two lowest round scores will be
To avoid ties in the classification concerning the five best scores,
"classification rounds" are flown until the ties are broken. If this is
not possible, the result of the discarded round will determine each
competitor's position in the final classification.
Organisation of the Contest: The competition must be held
at a site which is suitable for slope soaring.
When marking the starting and landing areas and the turning planes, the
organiser must take into
account the configuration of the terrain and the wind direction.
Changes: Any changes in the flight and landing areas may
be made only between flight rounds.
Interruptions: A round in progress must temporarily be
If these conditions arise during the flight the competitor is entitled
to a re-flight.
- the wind speed constantly is below 3 m/sec or
more than 25 m/sec.
- the direction of the wind constantly deviates
more than 45O from a line perpendicular to the main direction of the
A round in progress is to be cancelled if:
- the interruption lasts more than thirty minutes;
- fewer than 50% of the competitors have been
able to perform the task caused by marginal conditions. Without the
condition "constantly" (i.e. 20 seconds) have been met and thus caused
