I was just about to head out for a flight, checking things over and found this. **** it! It is three months old and I really do not want to send it away and risk getting it back in worse condition or trust that something else will not go wrong. It flies perfect as it is...well before the cracks. I guess it is still safe to fly like this? I put a zip tie on the arm for a little extra strength. I guess they do come in handy. It feels pretty solid and I did a short test flight, it seems okay. I never hit anything and always hand catch it when landing and it is kept in a molded case when I do not use it. Geeze this is disappointing. How do I get in touch with DJI to start a a warranty claim?
