Malo sam se procunjao netom u potrazi za nekim logerima/limiterima koji ce sigurno postati popularni nakon definitivnog usvajanja pravila 200W/min. I evo sta sam nasao:

- Logger/limiter: UniLog firme SM koji se danas masovno koristi na F5B takmicenjima. Ima softver koji lako menja ogranicenje maksimalno utrosene energije i nakon toga iskljucuje napajanje prema motoru. Nije jeftin ali vrlo mocan s'obzirom na broj dodataka koji se na njega moze zakaciti: http://www.sm-modellbau.de/shop/
- Limiter firme Neu: parce elektronike bez ikakvog moguceg proramiranja (samim tim i manipulacije) sa vec predefinisanim cut off za predvidjenu utrosenu energiju. Danas se pravi u 2 varijante za F5B (1750w/min) i F5D (1000W/min) mada sam siguran da ce brzo izaci i neka varijanta za F5J sa 200W/min. Jeftin i pouzdan sistem i verovatno sledi pojava dosta slicnih sistema http://www.direct-rc.com/shop/F5B%20F5D%20limiter . Ono sto im danas fali je da moze da se ocita vreme za koje je energija utrosena.
- ESC sa integrisanim loggerom: Turnigy (Hifei King Kong) sa novom serijom ESC koji sadrze dosta kvalitetan loger u sebi. U teoriji (koliko se ja razumem u problematiku) sa novim firmware mogli bi da se pretvore i u limitatore koji bi ukljucili cut off nakon potrosene energije. Danas vec postoje verzije sa 20A, 40A, 60A, 80A http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=10943&Product_Name=Turnigy_Super_Brain_80A_Brushless_ESC
- Eagle tree E-logger: klasican loger. Ima prednost sto na njega moze da se zakaci gomila dodatnih sondi i dodataka kao GPS i OSD.

Ono sto sam procitao po forumima je da ljudi nisu bas odusevljeni celom pricom jer ko ima jaci motor brze ce se peti na visinu i imati vise vremena za jedrenje koje se boduje tako da i 2kW nece biti retka pojava. Takav motor kosta sa kontrolerom oko 350E i vec se najavljuje Junior F5J kategorija samo sa outrunnerima od 35mm bez redukcije i max 4S za nekih 800W ili cak i ogranicenje do 2m raspona i outrunner od 28mm bez redukcije sa 3S.

Posto pratim diskusiju na RCG u koju se ukljucilo i podosta FAI delegata bogami povelika diskusija se razvila. Ima jako puno zemalja protiv formata takimicenja koji sam okacaio pre par nedelja ovde a koji je na dnevnom redu FAI komisije. Totalno je neizvesno sta ce biti 16.4. u Lozani i koji F5J format ce biti usvojen.

No, da ne bi bilo zabune, u Ceskoj, Slovackoj, Sloveniji, Madjarskoj, Hrvatskoj i verovatno u ostalim zemljama naseg regiona se intenzivno leti sledece: Eurocup F5J & F5J-400 Outrunner

http://f5j.eu/w/index.php?title=Eurocup_F5J_%26_F5J-400_Outrunner#F5J-400_.22Outrunner.22

Prakticno 2 kategorije, jedna Senior gde su modeli oko 3m i druga Junior gde su modeli oko 2m ali sa dosta jakim ogranicenjem po pitanju motora:

F5J

No limitations on the motor type. Propulsion battery can have maximum nominal voltage of 12V or any number of cells, as long as the battery pack is not heavier than 425g. Battery wrap, cables and connectors are part of the battery pack weight.

F5J-400 "Outrunner"

Models of this category can conform to either of these rules:
- standard F5J-400
- unmodified 400 motor without metal ring
- 8x NiCD/NiMH or 2x LiPO
- minimum model weight 500g
Outrunner
- outrunner with 28x26mm outside dimensions, 22x9mm stator dimensions, direct drive, unmodified (must conform to factory spec) (example: axi 2208)
- power source 2x LiPO
- smallest propeller diameter is 250mm (10")
- minimum model weight 500g

Eto puno tema za razmisljanje.

Posto je pravilo oko tipa dozvoljene baterije bilo nejasno napisano postavio sam pitanje na RCU coveku koji je Madjarski FAI predstavnik i jedan od organizatora F5J Eurocup i dobio vrlo kvalitetan odgovor.

Evo ga moje pitanje:

Hi Laszlo,
we finally have had also in Serbia organized a competition, by VMK Subotica, with EuroCup rules and 8 competitors:
http://rcfly4um.org/index.php?topic=...22561#msg22561
It was just the beginning with generally very basic models but we plan to have a 2nd round in September probably on a much higher level with specialized models. Very probably we will also try to attend some competitions in Hungary and Croatia this year.
My question to you is regarding the battery type as the rule seems to be not very clear, at least in the way it is written: Is the nominal Voltage of 12V only allowed or just any Voltage as long as the battery pack is max 425g? I am asking because many friends have a doubt what drive train they should get for their next model?
Thank you, and hope to meet you at some competition this year.
Velco


i njegov odgovor:

Hi Velco
I am glad receiving your info, and congratulation for the very nice F5J models we could see in your photos.
From the F5J Eurocup rule:
"Propulsion battery can have maximum nominal voltage of
12V or any number of cells, as long as the battery pack is not heavier than 425g."
This means:
1. If your battery is max 12 V: no mass limit
2. If your battery mass is not more than 425 gr there is no Voltage limit.
We are working on the modification of Eurocup rules for 2011 and the rule could be the following about the battery:
The mass of battery could be max 280 gr (or 300).
(This means there will not bee voltage limit.)
It is possible that the Krsko round will be organized together with the Hungarian round in September at Kiskunfélegyháza, (10-11-12 Sept) so you could participate on both F5J Eurocup competition if you like 120 km from Subotica, and there will be other two F5J competition in Szeged in September and October
See you soon.
Best regards,
László


Ukratko: ako je baterija do 425g nema V ogranicenja, ako je preko onda max12V. A za 2011 280-300g bez V ogranicenja.

E pa ljudi, mislim da kako imamo jako puno kvalitetnih takmicenja u nasem okruzenju mogli bi i malo da im se pridruzimo.

Evo jednog modela koji jako lepo jedri a ne kosta puno. Po stranim forumima su ljudi puni hvale o tome koliko je model dobar http://www.rcgroups.com/forums/showthread.php?t=922599 .

Komplet model u sa motorom, kontrolerom i servoima u  Svaji ili Lindingeru je 127E.

Evo jednog vrlo zanimljivog modela za mirne uslove letenja. Obavezno pogledati i kraj druge strane gde je video!
