i suggest to make a quad by yourself. It'll cost u under 10K!!
Coz if some website offer ARF then it is offering it without TX Rx and Battery,charger which cost around 3.5~4K
So 7K+3.5K~12K
only Rc Mumbai is offering 350mm RTF for 10K but Out of stock
Best way is DIY.
Look in 'For sale' for cheap motors,esc,charger.Buy NEW battery,Tx rx and Flight controller.
Make a aluminium frame size~450mm by Anycopter frame.
