The esc sensor on one of my P-3's motors suddenly died after only two flights. I had to send it to CA for repair (should be covered by warranty). This was about 6 weeks ago. The only notice I received via email was that they had received my unit. Nothing more since. ANYONE ELSE HAVE THIS PROBLEM, i.e. horrible communication with DJI tech repair, etc. Anyone else have a repair pending? If so please comment on your experience with DJI. GREAT PRODUCT + HORRIBLE CUSTOMER SERVICE!
