Title: Epptasy 80cm
Post by: ak on June 15, 2012, 04:38:53 PM
Kako je vremena sve manje i manje postaje sve teze odvojiti ga za ozbiljnije odlaske na livadu kada samo pakovanje i transport znaju da potraju.
Zato je zgodno imati nesto dovoljno malo i otporno da moze da se nadje u gepeku automobila kad god postoji sansa da se malo leti, a da ne zauzima mnogo prostora.

"Podrezivanje" ivica repnih povrsina kako ne bi smetale pri pomeranju.

Sledeci su hinges/sarke/baglame kako god da se zovu. Hteo sam za promenu da probam interesantan metod.
Umesto klasicnih sarki, bilo da su CA hinges ili parce fiberglass trake sa obe strane, ove se prave samo uz pomoc UHU por lepka.

Prvo se na kontaktnim povrsinama, gde bi pokretne povrsine trebalo da se spajaju sa fiksnim, krep trakom uokviri najistureniji deo sirine oko 1mm na obe strane, na koje se nanese UHU por lepak i ostavi 10 minuta.
(https://lh3.googleusercontent.com/-y1116PNd230/T_IUpwfJHxI/AAAAAAAAAug/cyLsboye-pA/s800/UHU_Por_hinges.JPG)

Na zalost, jedna od osobina EPP-a je i da se retko koja traka hvata za njega sto je slucaj i se krep trakom koja se vrlo brzo odvojila i sloj lepka je na nekim mestima siri od 1mm.
Odlicno drzi, ali su kontrolne povrsine malo teze pokretne za HXT500 servoe.

Na elerone ce ipak ici nesto klasicnije.

U medjuvremenu je palo i prvo farbanje. Krep traka je odradila svoje i farba se podvukla ispod ivica.
Ocekivao sam da se farba nece bas tako dobro hvatati za EPP ali se ona drzi dovoljno dobro da je nemoguce skinuti bez ostecenja.

Posto me oblik podseca na Tucano ideju za kolor semu cu da "pozajmim" sa jednog od njih.

Danas su zavrsene i sarke/hinges za elerone. Prva varijanta je bila sa fiberglas trakom ali se ona brzo odvojila od EPP-a pa sam je zamenio sa CA hinges ulepljenje UHU por lepkom.
Povlacim ono sto sam rekao za UHU por hinges na repnim povrsinama. Posle malo "razrade" tj. mrdanja rade savrseno.

Hornovi su lepljeni epoksi lepkom.

Servoi su sigurnosti radi lepljeni sa par kapljica pistoljem (hot glue gun) kako bi kasnije u slucaju zamene bilo lakse izvaditi servoe.

Zavrsen je i nos modela u koji je obaceno parce avio spera koje izigrava firewall.

Finalno sklapanje je u toku.
Prvo lepljenje glavnog krila i horizontalca za donji deo trupa modela a zatim se lepi gornji deo trupa.
Ali pre toga, veze izmedju servoa i kontrolnih povrsina. Kao pushrod su koriscene karbonske sipke 1.5mm debljine.
Veza sa servoom je odradjeno termobuzirom a na drugoj strani klasican linkage stopper.

Hvala, vec je bio ali je vreme bilo malo previse vetrovito za njega pa se "otimao".
Moram malo da mu povecam i expo. Sve u svemu ima potencijal.
