The first video, 100'000 plants a day with one drone? What capacity seed hopper? What weight per seed? As with most of these drone promotions pretty fanciful. I am not against UAV's, just the bullsh!t they peddle. There are some very able UAV's and countries that utilise them to their full potential, most I have seen in Australia are hobbyists or gov bodies who were sold a flawed concept and spend way too much for what they get.
The Turkish Bayraktar is an example of a capable multi role UAV.
