We all know dji are replacing shells under warranty which is great. However they don't seem to be replacing them with the latest shells design that are on there new crafts. A friend at our club sent his back last week for shell replacement and hats of to dji they turned it round and got it back to him today, he sent it of to the dji repair centre in the Netherlands from the UK last Tuesday so that's a great RMA turnaround time. How ever its come back with exactly the same design shell. I know there has been 4 shell designs so far but this has come back with exactly the same shell design as it was bought last june, its not got the extra tabs and its not got the bigger vents. So it might seem dji are replacing shells with older shells in hope of just getting them through the warranty period maybe. My whole craft was replaced under warranty a month ago from a uk retailer who said it had the latest shell, no extra tabs but it does have much bigger vents. I know mine only might be the second or third shell design but you would have expected dji to replace his shell with the latest one but hey have not. Very disappointing.
