Its not a matter of right and wrong. Its a matter of choice. I will not be able to land my Mavic until June. There wont be a spot with out a foot of snow on it for months. I am not going to carry something with me everywhere I go to land the drone, so I will hand catch till then, ideal? No but I make it work. I understand the risk, but have limited options until then. Given the option of landing on flat cement or catching it I would be stupid to catch it but we don't all live in warm Arizona or Texas haha! If you don't understand the risk of reaching up under 4 props spinning you shouldn't be flying this drone, the risk is there, its up to you to minimize it with whatever method you feel is adequate.
