If I understand what indranil is saying, the canards will be driven by actuators but used only to manage the vortices over the wing rather than for pitch control. I would expect the latter to require radical changes to the flight control software.

Re: Indian Military Helicopters

Just 600lb for three operators and their equipment? These guys carry easily lug around 75 to 100lb each in addition to their regular weight, which I'm guessing is going to be about 200lb each.

If the limit is 600lb they would have to limit to two or even just one in extreme cases.
