Well I'm gutted to report that my 6 week old P3A has come back from a flight today with the dreaded cracked shell around the motor screws! I have always flew this bird cautiously & it has never been crashed, & on all of the 20 odd flights I have hand caught it, so no heavy landings. However today I have developed a hair line crack about 10-15mm long in one of the front arm motor bolts areas. To be honest I don't want to send it away to DJI for shell replacement, as it will be away a very long time, & also there is no way of knowing that if they replace the shell it wont happen again after a few flights. For the record this is a P3A with new motors & the so called reinforced shell. I really hope that the new yuneec lives up to the hype, as I would not hesitate to jump from the DJI ship, as I'm sure many others also feel the same about. What is the best way to stop this crack from spreading further until DJI get their RR's in gear & sort out this problem?
