About this 3D model

Blade mCP X Rotor Head Linkage Set usage: I have drilled the two holes by hand. Tools: 1.5 mm and 2.0 mm drill bit Then i used a soldering iron for the last touch that it "clips in". --------------------------------------- i have ordered 3 new pags with 24 pieces but the shipping needed quite long form USA. so i designed and printed my one linkage set - and it worked very good! similar to BLH3522 http://www.horizonhobby.com/products/BLH3522 like: http://www.ebay.at/itm/321226543895?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 or http://www.der-schweighofer.at/artikel/89325/rotorkopf_steuerstangen_blade_mcp_x_8 or http://www.amazon.com/Blade-Rotor-Head-Linkage-Set/dp/B004M13Z7S
