Hello, three days ago after a normal flight I did a check on my phantom and saw a minor crack. I attach pictures. I have never crashed, hardlanded and never used prop guards. What do you think I should do? Should I replace the shell now that the crack is minor? Is it going to be any worse if I continue to fly? I wanted to mention that I live in Greece and bought it from a greek e-shop, online. We have here an authorized service by dji. Will it be under warranty? It is only three months old. I am thinking to buy aluminum motor reinforcements. Will that prevent the extention of the crack? Thank you.
