Visinomer i motor tajmer za F5J

(1/3) > >>

SloMi:
Da li neko ima informacije gde može da se nabavi visinomer sa motor tajmerom koji odgovara novim FAI propozicijama za F5J?

Ja znam za neke firme ali nigde nije to ono što se traži po FAI.

Firma http://www.hyperflight.co.uk/ ima u odeljku Electronics:
-RAM 3 Recording Altimeter for Models, masa 3.3g,  nema displej, cena 69 LSTG
-CAM Height Limiter, iskljucuje motor posle 200m visine, ili posle 30s, cena 42 LSTG
-RC Electronics Height Limiter, 9g,  nema displej, ugradjena fja iskljucenja  i motor run tajmera, nema na lageru, cena ? Vise o ovom poslednjem moze se naci na http://www.electricsoaring.co.uk/altimeters.html gde je navedena cena od 68+3 LSTG

Firma http://www.eagletreesystems.com/ takođe ima mnoštvo raznih uređaja za telemetriju, sa memorisanjem podataka o parametrima leta, između ostalog i o visini, brzini, preopterećenju, itd. ...  Interesantno je da Hobby King prodaje EagleTree proizvode, ali nisam proveravao da li su jeftiniji ... pa ipak ni kod njih nisam našao ono što treba po FAI. Gledao sam i kod nekih modelarskih firmi ali izgleda da toga nema baš svuda, ili se tek čeka da to neko napravi, pa da onda Kinezi to umnože u par miliona komada i obore cenu na pristojan nivo ...

Isto tako nije mi jasno zašto se FAI opredelio za ovako komplikovanu proceduru kada je imao na raspolaganju rešenje koje su već koristili Englezi na svojim F5J takmičenjima, a to je isključivač motora kada model dostigne 200m visine i/ili prođe 30s od početka rada. Izgleda da taj sistem nije bio baš preterano pouzdan, ali to su samo moja nagađanja...zaista bih voleo da znam više o tome...

Pozdrav,
Slobodan

SloMi:
Ko o čemu, baba o uštipcima. Ja opet o F5J. Malo sam čeprkao po internetu, i gledao šta i kako to rade knzervativni Englezi. Toliko su  konzervativni da iamaju preko 500 takmičara u F5J po njihovim pravilima, a hvala Bogu pravila su po meni bolja od onih po FAI.
Ali evo gledajte i sami:

http://www.electricsoaring.co.uk/esoaringrules.html
BRITISH MODEL FLYING ASSOCIATION

7.12  eSoaring (Height Limited Rules) Class.
----------------------------------------------------------
---------------
--------------

Appendix -  Approved Height Limiter Switches

In order to gain approval, any height limiting switch must demonstrate that it will consistently enable an electric glider, when operated within the rules of the competition, to finish it’s launch phase at an ISA 15C pressure indicated altitude of 200 meters or after 30 seconds (40 seconds for 2M Class models) of motor run time, whichever occurs first. This requirement must be met whether or not the unit incorporates an ‘anti-zooming’ feature.

As of January 2012  the following devices are approved.

Manufacturer RC Electronics

Part Number: RC Altimeter #2 BASIC (with firmware version 2.08 or 2.12 (or later approved versions)).

Manufacturer RC Electronics

Part Number: RC Altimeter #2 PRO (with firmware version 2.08 or 2.12 (or later approved versions)).

Manufacturer RC Electronics

Part Number: RC Altimeter #3 PRO (with firmware version 3.05 (or later approved versions)).

Manufacturer RC Electronics

Part Number: RC Electronics HLS (with firmware version 1.00 or later approved versions)

Web address for RC Electronics is: www.rc-electronics.org

Note the difference between these two units is that the PRO version can also provide a telemetry link. The functionality of the unit in terms of height data logging and altitude switching is exactly the same as the BASIC unit.

At least three alternative devices are known to be in development and, once they are commercially available and have gained approval, they too will be listed for use in these events.

Ovo je samo isečak iz propisa koji se odnosi na ograničavač visine.
Ostalo nisam navodio izuzev što ću navesti da oni imaju klasu F5J Open što se odnosi na modele jedrilica do 4m raspona maksimalno, i F5J 2m što se odnosi na modele raspona krila do 2m maksimalno, i
mislim da je takva podela mnogo normalnija nego ona na F5J i F5J-400. Po meni F5J-400 je dekadentna varijanta koja ne uvažava napredak tehnologije jer favorizuje prevaziđene elektro motore
sa četkicama, i NiCd/NiMh baterije.

Pitao sam Gospodina Martina da li ima uređaj (visinomer sa displejom i motor tajmer) koji zadovoljava nova FAI pravila za F5J, a on mi je odgovorio:

Hi Slobodan

Yes - the RC Electronics Altimeter Basic #2 with FAI F5J firmware satisfies the rules and the proposed altimeter specification. This works with the Programming Card Reader which is plugged in after the flight to show FAI start altitude.

At present this is the ONLY altimeter that passes the requirements in every way, but we hope that before long 3 more different unit will also be available.

Best Regards
Martin

Dakle to je to, za sada. Pokušaću da saznam i cene ...

SloMi:
Evo sada imamo predpostavljam sve podatke o potrebnom altimetru/tajmeru za F5J po FAI,
i Šta, i Gde i Pošto:
1. Od Martina:
-------------------
Hello Slobodan

RC Altimeter #2 Basic                      £68.00 (This is by far the most popular, with over 550 in use in the UK alone, and the most used unit world wide. It is adjustable in 1m / 1sec intervals)
(With USB interface plus software etc on CD)

RC Altimeter Programming Card    £60.00 (For quick and easy FAI F5J height checking & checking and setting of eSoaring rules parameters (in conjunction with appropriate firmware) on the flying field)

USB A Cable to Mini 5 pin                 £  4.95 (Most people will already have a suitable connecting cable as it is commonly used for digital cameras)

Shipping to Europe is at cost, but  £12.00 is normally sufficient.

Please let me know if you need any further information.

Regards
Martin

2. Od ZMH Shopa

Dear Slobodan,

thank you for your interest.  Info about altimeters suitable for FAI-F5J you can see here (including the prices):
http://www.rivamodels.sk/ZMH/ZMH_09.html
If you have some additional questions, don´t hesitate contact me one more time.

With best regards

Palo from RIVA models / ZMH-shop

---------------------------------------------------
I sada umesto zaključka mogu da konstatujem da ova posebna elektronska oprema za F5J
po FAI propisima postoji, može da se kupi po doduše malo većim cenama od onih na koje smo navikli kod Hobby Kinga, ali će verovatno te cene padati obzirom na već veliki interes u Evropi, a i šire, za ovu izvanrednu klasu RC modela, za koju cenim da je budućnost
takmičarskog RC modelarstva. Mislim da bi ova lepa i izazovna klasa mogla da otpočne i kod nas, jer potencijal imamo, propise imamo, modele imamo ili možemo da ih napravimo/kupimo, ljude  takmičare imamo, pa šta nam još fali? 

Pozdrav,
Slonodan
