Planning to buy a 2.4GHz Flysky FsIA6B receiver from banggood , will customs be an issue? The equipment is type approved as i got to know from a pdf file posted here in rcindia.org

Why risk this, there are local hobby shops where you will get this item. BG has been uncertain since a few months.

buy it locally it will get stuck

Ordering from China is risky and banggood is uncertain. Sometimes things come and sometimes don't.
If you want peace of mind order from LHS.
If you want to save few pennies at the cost of your peace of mind then go ahead and buy from Banggood or aliex or any Chinese site.

yeah can't compromise with peace of mind  , i guess
