This contest is a multi-task event for RC Electric Powered Motor Gliders which includes two tasks.
a) Distance
b) Duration and landing
These two tasks are executed without interruption in one flight. A minimum of two flights must be flown.
The weight of the power source including insulation, cables and connectors shall not exceed 1,1 kg.
In case the weight of the power source and the number of cells shall be checked, this shall be done immediately after the end of the flights.
Two imaginary vertical planes at a distance of 150 m determine turnlines and are named Base A and Base B. A safety plane is established perpendicular to these planes. The safety plane is endless. The sighting devices used to detect the crossing of the Bases A and B are placed at a distance of 5 m from the safety plane.
At Base A at the other end of the line begins an imaginary gate 50 m wide and 3 m high. The width of the gate is to be marked on the ground. For landing the organiser must provide two concentric circles of resp. 30 and 15 m diameter, located at a place on the field where no danger of collision exists with models simultaneously flying either the distance or gate task.
a) For each flight the total score is compiled by adding the partial score A and B for each competitor;
b) If more than two flights are flown, the lowest flight 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;
c) In order to decide the winner when there is a tie, the distance part of a flight is repeated.
a) Before launching, the pilot has to show to his timekeeper how he controls his motor(s) on his transmitter (on, off, reversing);
b) The launch will occur outside the course, and within 10 m from Base A;
c) The model is released or thrown into flight directly from the hands of the pilot or his helper, without assistance. The model shall not be launched from a height greater than the flier's normal reach above the ground.
a) This task must be completed within 180 seconds from the moment the model is handlaunched. Time of release is to be taken by one timekeeper.
This task must be carried out with at least two climbs with motor running.
The pilot has to decide how much time he will use for each climb (motor run) and how much for gliding.
b) Starting and stopping the motor must be announced to his timekeepers;
c) When after stopping the motor the model in gliding flight first crosses the Base A in the direction of Base B, the timekeeper starts counting the laps. The model must complete as many laps as possible from the starting point Base A to the Base B and return;
d) Restarting the motor stops counting the laps, as does the expiration of the 300 seconds.
e) A timekeeper announces to the pilot when his model crosses the Base A and a flagman (or audio system) is used to signal crossing of Base B. The absence of a signal will indicate that the model has failed to correctly cross the base. The instruments used to check the crossing of the vertical plane must assure the parallelism of such planes.
During the scoring in this task and until the pilot has been signalled, the model must fly on the side of the safety plane where the gate is positioned. Flying with any part of the model on the forbidden side of the safety plane will give ZERO points for the whole flight, distance and duration.
f) The pilot, his helper(s) and the team manager must remain at Base A until the distance part of his flight is completed. Nobody, other than the flagman, may stay in the B line and give signals.
g) Every completed lap will be awarded 6 points. When the model fails to complete at least one lap after either of the first two climbs, 30 points will be deducted from the score of this task;
h) After this task the pilot has to fly within a minute through the gate (as per 5.5.4.2.) in the direction from Base B to A. Passing the gate with the motor off at the end of the last lap is allowed and shall be announced at least 50 m before passing the gate with the word "LIMBO".
a) This task must be completed within 300 seconds from the moment the model passes the gate;
b) The pilot has to decide how much and how often he will switch on the motor;
c) The gliding-time timekeeper (1) starts his watch every time the motor is switched off. Gliding time ends either when the motor is switched on again or when the model comes to rest after landing. The pilot must announce the switching on and switching off of his motor to the timekeeper with the word "ON" and "OFF";
d) Gliding time is cumulative and one point will be awarded for each full second the model is gliding;
e) One point will be deducted for each full second flown in excess of 300 seconds;
f) Additional points will be awarded for landing; when the model comes to rest in the 30 m circle, 15 points will be given while coming to rest in the 15 m circle gives 30 points. The distances are measured from the centre of the circle to the nose of the model;
g) No additional points will be awarded if the landing occurs more than 330 seconds after beginning of this task (as per 5.5.4.6.a)).
The competition must be held at a site having reasonable level terrain with a reasonable low probability of slope or wave soaring.
