I wanna buy as my first drone a Sub250 Nanofly 16,
With Zorro ELRS controller. What should I buy with it? I also need goggles and everything else

I wouldn't get the Zorro, maybe the RM Pocket instead of it. Get the ELRS version. Pocket uses cheapo 18650's as opposed to the Zorro with it's more expensive 18350 batteries. Both have 250mW RF output if running the FCC version. It's also half the price of a Zorro. Use the money you save to buy more Lipos.

Goggles wise, Eachine EV800D would be a good starting set or BetaFPV VR03.

You will need a battery charger and batteries beyond that. SkyRC B6AC charger, ViFly 1S Whoop charging board (PH2.0/GNB27) and 10-20 GNB27 1S 450 Lipos, which would get you around 30-60 mins of flight time. Alternatively for charging, you could get a Whoopstor v3 and some PH2.0 to GNB27 adapters or BT2.0 to GNB27, to allow charging of those Lipos. Very few chargers support GNB27 natively.

Ok thanks
