The parts do not fit well, especially the engine fitting into the fuselage, the wing top and bottom halves, and the front and rear fuselage. The most infuriating bit is that the fuselage is molded in 4 pieces, which causes a lot of fit problems. This is also extremely tail heavy, so you have to weigh the front down. While the end product resembles a Mig-15, the build process was slightly frustrating. At 1/48 scale, this is also pretty small when it is complete. If you want to tackle this, get your putty and sandpaper out.
