@VTOLkarthik,

Despite your contention that you are not importing, the fact is that you are. And then you will re-export when you go back.
I fear that this import/ bond for duty amount / re-export mechanism may not apply banned items like drones.
My guess is bringing in a drone is not worth the hassle, unless an imp/exp expert advices you otherwise.
I doubt if it will be allowed.
One has to surrender to local regulations.
Let me give an example. In July, I did one flight at a US model airfield, before someone asked for my AMA membership card. Use of the field was free, but you needed AMA membership, and the insurance cover.
Before flying there again, I got ‘Affiliate membership’ for me and my wife.
Moral: probably not worth it!
Leave your drone behind and enjoy time with friends and relatives
