Ker sem bolj začel spremljati F5B kategorijo, sem ugotovil, da imajo na koncu tudi "duration task" - jadranje. In to kar 10 minut. Po tem pa pristanek v točko.
Opa!
Kakšne podobnosti z F5J!

Torej na 9 strani in naprej.
Če pogledamo zahteve o modelih:
Minimum weight ............................................ 2000 g
Maximum battery weight................................ 1100 g
Maximum number of cells.............................. 30
Maximum suface loading ............................... 75 g/dm 2
In pa potem jadranje:
5.5.4.6. Duration and Landing Task
a) This task must be completed within 600 seconds from the moment the audio signal is given;
b) The competitor has to decide how much and how often he will switch on the motor;
c) The gliding-time timekeeper (1) starts his stopwatch every time the motor is switched off. Gliding time ends either
when the motor is switched on again or when the model aircraft comes to rest after landing. The competitor 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 aircraft is gliding;
e) One point will be deducted for each full second flown in excess of 600 seconds;
f) Additional points will be awarded for landing; when the model aircraft comes to rest in the 30 m circle, 10 points
will be given while coming to rest in the 20 m circle gives 20 points, and when coming to rest in the 10 m circle 30
points will be given. The distances are measured from the centre of the circle to the nose of the model aircraft;
g) No additional points will be awarded if the landing occurs more than 630 seconds after beginning of this task (as
per 5.5.4.6.a) ).
Zdaj bi bilo dejansko dobro izvedeti, koliko se uporablja motorja v teh 10 minutah. Vendar sklepam, da je konkurenca kar huda in da ni kaj dosti vklapljanja, če sploh.
Kako dobro torej jadrajo 2 kg modeli pri razpetini 1.7 do 1.9 m s površini 26 kv. dm?
Torej na nek način je to zelo podobno z F5J.
Poleg odprte F5B FAI kategorije imajo še ponekod:
F5B-400

F5B-7 in F5B-10 aka F5F

Nova pravila za 2005:

Model aktualnega sv. prvaka:

) da se da mogoče kaj naresti v F5J - 7 oz unlimited tudi z F5B mašino z lahko motorizacijo. Masa - dobra kila do 1.2 kg!
in pičlim v-lomom... jadranje ni glih v prvem planu.
