@traxxrc1 - radio's can still be detained and also you will end up with the good amount of service charges (don't calculate with 14-15% of tax, calculate with 35-40% in total). So it's better if someone carry it or some LHS gives at good deal.
I am not considering the radios coming from HK or china, but if that looks sophisticated then it may be a issue. check the thread -
http://www.rcindia.org/rc-india-forum/custom-clearance-fcc-certificate-conformity-certificate/ . Other than radio/high capacity batteries i think there won't be an issue. and with small items like cable or others, but big boxes will attract the attention.
this is my exp. but may be many people may be lucky.
