Problem with DRDO is they refuse to learn. They are habituated to free money and lack of accountability. If they sit on their fat a$$ and do nothing they will get their salary and other benefits, if they toil and work hard still they will be getting the same money and no extra incentives. So why work hard?It appears that DRDO is to learn the drone technology from RC air craft models made by school students of western countries and they fly successfully RC models with video camera mounted on it. DRDO has come out a shame for India.
