I am Romanian too btw , I'd love for the LanceR , the IAR-99 and so on...but what was your point? Saying that the LanceR would never happen? Why? It's literally the MiG-21 , with avionics in the cockpit like the F-16 just in different places really....that's not all tho . And info on the LanceR isn't that hard to find , you can literally spend some hours researching and you will find a lot of stuff which can help for a MiG-21lanceR Module.
Long story short , a MiG-21LanceR module is easily possible , i would see it as letherNeck taking the current MiG-21 module , making a new 3d model for the new cockpit , making the avionics and so on. Then adjust the flight model here and there...
Anyways , im more so confused by what was your point...saying that the lanceR is so complex that info on it will never be found or what lol??
