Comrade, cool down a bit, try to listen what others on this thread have already told you. All that is priceless advice. The first step to becoming a better pilot is not blaming the simulation or the sensors, try to see what you did wrong in the first place. I see that you are very passionate, and that passion will go a long way, but try to listen (its hard, I know, but helps in the long run).
A great pilot will never complain about the equipment, but use what's given to him in the best possible way.
Use the MiG-29 the way its was supposed to be used, i.e., GCI guidance, point defense, attack bombers/ground attack aircrafts. Don't try and use it like a F-15 or a Su-27, you will most likely get killed that way. The VVS and PVO of Russia certainly didn't/don't use it that way. Notice the latest Syrian conflict? Did you see Russia use any MiG-29s for escorting their bombers/ground attack aircraft? That tells you something don't it?
BTW, on topic, the MiG-29s EOS equipment is not as good as the Su-27 or Su-33. In fact, the Su-33 in real life supposedly has a better EOS than the Su-27 (don't know how far that's true though).
