I'm offering my DJI Mavic Air 4K with lots of extras, including three batteries (each lasts 18-20 minutes of flight time). Polar Pro ND filters (ND4, ND8, ND16, ND32, ND64, ND4-PL, ND8-PL, ND16-PL), controller, new low-noise propellers from https://www.masterairscrew.com, and a hard case. Also includes one SanDisk Extreme 64GB U3 microSD card.
To fly the drone, you need to download the free DJI Go 4 app onto your smart phone or tablet, which you connect to the controller.. I can offer an iPhone SE with the DJI Go 4 app pre-installed for an additional €10/day.
