I've never seen a drone like this. It's too fast to be a drone and it moves into the water.
This 'bird' is flying 200 km/h fast. It's faster than many helicopters.
>600mkg or some shit because you don't know proper measurement units
m8, we're not the ones measuring things in feet and yards and sticks and berries.
There is a reason why scientists (and that includes those in the US) adapt the metric system instead of working with imperial and hoping it will somehow work out.
