Sorry 9Aplus, but tailbooms were made at PZL. Not sure if they are now or not, but they definitely were, and the early ones coming in to the factory in Italy in 2005 were crap! Factory used to spend a couple of days doing repairs to the exact same area on every tailboom. Top lefthand mount point, about 3 inches back from the front. They all came with a big lump there that had to be reworked. Early fuselages weren't much better with misdrilled holes and holes that weren't deburred. After about S/N 31050, things improved markedly in the build quality.
