I am going to India in Feb next year. I am going to carry my Mavic Air. I am a travel content creator on Instagram and asked a lot of my followers who are Indians or been to India with a drone. Your best option is to carry the batteries with you in (carry-on) and put the drone inside the check-IN baggage. Mavic Air is a very small drone and most of the custom officers in India don't even know about folded drones. Thus, Keep it in your check-in baggage to avoid any questions or hassle.
In case if you want to keep it in your carry on, tell them it's a camera with a stabilizer if they question you. Make sure you remove the propellers.
