Must often sticking parts on my remote-controlled helicopters. Since there are soft plastic (hoods and booths) and hard plastics (eg landing gear). According to the description on the tube of glue for hard and soft plastics to suck. Are you kidding me? Are you serious when you say that! After drying, a gum-like mass remains. Imagine, a landing skid glued with such a stuff that does not stop until lunch time. I'm disappointed. Two points, because it determines glued any substance.
