Has anyone else had their lower frame crack coming from the legs up toward the battery compartment? I have three hairline cracks. Two in the back coming from the legs and going in the direction toward the battery compartment ( a third of the way) and one crack coming from a front leg . I hand catch the phantom 4 from the right rear leg and have not had any crashes. I examine the craft regularly and just noticed these. I have sent the craft in to dji for repair for this issue as well as a crooked horizon issue (calibration did not solve). Has anyone else sent their p4 in for these issues?How long does it usually take to send in and get back? What is the usual repair cost.? Dji would not give me an estimate until they have seen the aircraft.
