Just got my p3a back from warranty repair.  It was sent in for a single small stress crack on one motor arm that appeared 11 months in to the warranty period.  DJI took care of everything and kept me informed of the progress.  My only complaint was them updating my AC firmware which left me to update the app and the RC to the latest as well.  I tried to avoid that by not sending the RC and battery, oh well.  Anyway the repair was done perfectly ànd I have just returned from a 1.2km test flight that went perfectly ànd had full signal at all times.
Thanks for the good service DJI.

Good to hear some good positive news.  Thanks for posting.  

We are sorry that the firmware was updated without your permission, please keep us posted if there are any further problems.
