No crashes ever all short flights and soft landings. Less than a year old  like 10 flights. Now I here the phantom 3 series is being discontinued will DJI  help me?

Sorry to hear about the cracks, I do suggest you to send it in if you purchased it less than 1 year, our engineers will evaluate it after receiving the unit, if the cracks are caused by product faulty rather than pilot error, we'll take care of the case for you.
