Hello. Recently I noticed that there is a problem with the rudder in Su-27. Flying at the speed of, for example, 700 km / h, kicking the rudder (even not too strong) causes the two rudders to be broken off. Earlier this situation did not occur. In general, I've found that recently the Su-27 fighting assets have deteriorated significantly. Is there any explanation for the changes introduced in the Su-27 flight model. Currently, it is the slowest and worst turning fighter.
