I was recentely making a quadcopter and was worried that the parts which I am looking for was not available in amazon niether in flipkart ( these are the two most common sities which we look for buying anything online) after checking in lots of websites I found an international sites which was offering all the parts but there was no delivery option in India so I have to choose any other site atlast I found all the products in ebay and bought them all from ebay, I must say pacakaging was good and all the products arrived in the time and all the products were looking good! Thx ebay
