Guys look at this post below about quads from TOI :
https://www.facebook.com/26781952138/posts/10153485466877139It says 1m quad with high resolution night vision camera weighs less than 2 kg and 2-5 hrs of battery backup!! Wish I have such a battery with me!!
Also a range of 5sq km!! Is it really possible!!
I don't understand from where TOI gets this kind of data!!
