Everyone needs to check theirs right now and after every flight. Mine had no cracks I was checking after every flight , the crack developed around one ferrell during a single flight the crack was not there before the flight and it was there after a short gentle flight.
I do not believe the phantom is safe to fly if the ferrells are cracked. hold the arm and twist the motor a bit at the shaft, you will see the crack open and close, the motor will feel as though it is a bit loose. severe or sudden braking could result in a catastrophic failure of the arm.
Dji's engineer's could correct this overnight, with a bolt on doughnut type ring on the bottom when redesigned as I described, above would eliminate any forces on the ferrell. The bottom shell would no longer ,just be hanging on the ferrell, off of the top shell. The shell halves would be essentially clamped together. The ferrell liners protruding off of the flat side of the doughnut that would slip down into the ferrel, would not even have to be glued to restore integrity.
This would only add a gram and a half or two of weight to each arm, The donut ring could be designed as a small fairing it could sweep back into the arm on each side of the led, stamp your logo in it ,make it look like it came on the P3, very easy.
Now what about the cracking that is likely to develop around the motor mount bolts. They could be repaired in the same matter. They might have to be glued though, but this could be done superficially. and then the bolt on repair applied. imagine a marble cut in half that would fit inside of the donut ring the dome shape would contain the countersunk bolt heads, with the same type of liner extending into the lower shell bolt recesses, same as the doughnut repair, the motor would then be clamped to the bottom shell instead of essentially protruding from the lower shell.
If you can picture what the bottom of the arms would then look like, I think you would agree that they would look very nice, maybe even better that they do now. If anyone is feeling creative with a 3d printer, using the design I described, could possibly create a viable product, while we are waiting on DJi |
