Deciding between the COBI MiG-21 Fighter Jet (Set #5919) and the MiG-21 MF (Set #5918)? We break down the key differences in markings, scale, and value to help you choose the right Cold War brick set for your collection.
Quick answer
Choose the COBI MiG-21 Fighter Jet (Set #5919) for Czechoslovakian and East German markings, or the MiG-21 MF (Set #5918) for Polish and Soviet markings. Both are detailed 1:48 scale models, but #5919 has a slightly higher piece count and price.
Markings matter: choosing your Cold War allegiance
The most significant difference between these two sets is the national markings. Set #5919 features Czechoslovakian and East German insignia, making it a perfect choice for fans of Warsaw Pact air forces from the northern tier. Set #5918, on the other hand, sports Polish and Soviet markings, representing the core of Eastern Bloc aviation. If you're building a themed collection, the markings will likely be your deciding factor.
Scale and detail: what to expect
Both models are built to 1:48 scale, meaning they will display consistently alongside other COBI aircraft in the same scale. Set #5919 (MiG-21) contains 381 pieces, while Set #5918 (MiG-21 MF) also has 381 pieces. The piece count is identical, so you get a similar building experience. The key difference is the specific variant of the MiG-21 being modeled; the MF variant represented in #5918 was a later, upgraded version.
Your decision rules
- Choose Set #5919 (MiG-21) if: You want Czechoslovakian or East German markings. This set is for you if your collection focuses on the northern Warsaw Pact states.
- Choose Set #5918 (MiG-21 MF) if: You prefer Polish or Soviet markings. This set is the right choice if you are interested in the core Soviet and Polish air forces.
- Scale and display consistency: Both models are 1:48 scale with 381 pieces. They will display well together, so you can eventually collect both without size mismatch. If you plan to build a squadron, either set will fit seamlessly with other COBI 1:48 scale aircraft.
