He he ano hoki te whakarōpū i runga i te formladegidov tau i roto i te rauemi rānei. A, no te, kōrero te ihirangi o runga ki te tekau milligrams ia karamu rau o taimaha o te rauemi e pā ana ki te E-1 piha tukunga. Ki te kei te kāpia i tekau ki te toru tekau milligrams, ka tohu te E-2 piha.

Ahu o mau api

Ko te āhuatanga toharite o te rauemi 1,22h2,44, 1,25h2,50, 1,52h3,05, 1,52h1,52 m. E kore te mea katoa tenei, engari anake te āhuatanga matua i runga i nei te kahupapa parewai. pea te matotoru o te mau papaa parau i te 9 ki te 40 mm.
