I chanced upon these at my local market. I think they're Chinese made models based on a better known brand's scale model but i'm not familiar with aircraft models. Each is around a dollar. The box says its 1:115 scale which I feel is wrong. More likely it is 1:144. Any one tried these? How do they build up? I think I saw 3 different helis as well as an assortment of fighters. I bought one of each, namely a US Apache ( which I think is missing some nose parts), a Chinese Harbin Z-9 and a Chinese WZ-10.
