Pozdrav!

Ponukan ovim Katana threadovima proguglao malo sto jos taj Sebart ima i moram reci da mi se ovaj Shark trainer poprilicno svidio.

Pa imam tri pitanja.
Prvo, obzirom da nikad nisam imao tako veliki model, zanima me da li je praksa da se krila skidaju prilikom transporta? Gledao sam ovaj assembly dokument i ne mogu skuziti. http://www.sebart.it/download/Assembly-Shark-30E.pdf (http://www.sebart.it/download/Assembly-Shark-30E.pdf)

Drugo, u tom dokumentu ima preporuceni power setup:
Motor:............................ Hacker A30-14L
ESC:……………………. X40 SBec-Pro
Battery: ….Flight Power 2500-3S or more
Propeller: …….…...………. APC 14x7E
Ima li mozda nekakav alternativni setup, mozda isti za manje para ili bolji za iste pare?

I trece, umjesto preporucenih servaca JR PROPO DS385 or DS381, mozda neki drugi?

Hvala!

Pozdrav M Fox,

1. Krila mozes skinuti prilikom transporta ako ti ne udje u auto,
ostavis ih ako je auto dosta velik ;)

2. Ima sigurno, npr. kod Hobbykinga
http://www.hobbyking.com/hobbyking/store/%5F%5F17921%5F%5FTURNIGY%5FAerodriveXp%5FSK%5F3548%5F970%5F850W.html (http://www.hobbyking.com/hobbyking/store/%5F%5F17921%5F%5FTURNIGY%5FAerodriveXp%5FSK%5F3548%5F970%5F850W.html)
i neki 60A BEC Regler

3. npr. HITEC

Super, hvala na odgovoru!

Molio bih jos samo osvrt na ova dva pogonska seta za Sharka, razlika u cijeni je ipak prilicna.

AXI su ti vrhunski motori a i Jeti je mrak ESC, zato je cijena veća, ali meni je nebulozna cijena i jednog i drugog :)
Radije nabavi sve to u Kini za trećinu love

Vrlo rado, ionako sam u HK vec brdo love ostavio. Moze par preporuka, nisam jos doma u dimenzioniranju pogona...?

EDIT: i preporuka za servace, da bas nisu zadnji drlog?

Npr. :)

I neki 50A ESC.

Za servače ti provjerim malo kasnije

Hvala Robi!

Za ovaj kaze "This product is no longer available and has been replaced by a newer product."
I onda ide link na drugi motor.

Ali recite vi meni momci... dakle imam model koji je 1400 grama prazan, ~1800 sa pogonom. I kazu oni treba 14x7 prop. Gdje da ja vidim koje sve gabarite bi motor trebao zadovoljavati da se avion jedva digne s piste ili da avion leti normalno ili da avion leti u svemir na trecini gasa? Ima neki kalkulator?

Skini app i tu možeš izračunati potisak

EDIT: i ovo može pomoći

Okej evo recimo primjer za ovaj skuplji pogon, cisto da krenem odnekuda

(http://i44.tinypic.com/2rr9hqs.jpg)

Dakle izaberem motor, esc i prop i eto kaze nece...

uzmi manji prop,
celije stavi npr. Turnigy 3S 3000 mAh

S tim da možeš staviti veći prop (14×7) bez problema i radit će ti, samo uzmi 50ak A ESC

Npr. ovo je moja konfiguracija, a radi bez problema
Ustvari je ovaj drivecalc loš :D

To ti je OK
Po meni, uzmeš ovog Turnigyja http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=18232 (http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=18232) i sretno letiš :)
Ili ovaj motor:

http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=18163 (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=18163)

Ti Aerodrive SK3 motori su savršenstvo za svoju cijenu, ne vjerujem kako su jeftini

Dakle

(http://i41.tinypic.com/2s6t5hj.jpg)

Ak veli static thrust 2115g a to je po nekoj racunici vise od model 1400g + 430g pogon/baterije, to bi trebalo letjeti :)

E sad, koji je omjer static thrusta i tezine da model leti 3D ili da model leti kao krava?
Koji je jos od ovih parametara vazan za dimenzioniranje

Ak hoćeš divljinu, uzmeš ovo:

http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=19831 (http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=19831)

To je otprilike ekvivalent Hackeru A30-14L, staviš 14×7 i imaš zvijer od trenera ;)
