I have purchased a flying drone from bangood, but it is not delivered yet. My drone reach to yurt disi customs and order no is 40569285. Plz reply why this item is not delivered.

Because it is BANNED

Mr.Kullu! You should've visited the forum before your purchase. Such a pity that the customs would have to fly it themselves.
Maybe they should start an RC store

Just came to know one of my fellow flier got "Reptile S800" flying wing racer kit delivered from bangood.
This was just foam kit no electronics inside so no customs issues.
