Russian engines are better than anything Indians can come up with, that is to say Indians even make engines - which they don't. This is not an engine problem, but an Indian problem. Indian pilots often are not qualified for the job, when they get into the plane/jet, not only are they endangering their own lives but also lives of others.
No point buying these expensive foreign jets if you can't even operate them efficiently - remember, only an Indian can disgrace the name of a well known jet and turn it into something now called the 'flying coffin'.
