Did all these cracks appear after one specific flight or over time?
I keep thinking there are some bad batches out there.
Some people report major cracks, others nothing.
In my case, after about 30 or so flights. No crashes, no abuse, always very carefully hand caught, careful attention to prop tracking.
Probably the machines that don't crack are, ironically, less well made than the ones that do. The problem is the extreme stiffness of the arms and complete lack of shock mount on the motors. If a poorer, more flexible plastic is used, or the assembly is a little shoddier on a particular batch, that probably helps the situation and those machines stay together longer.
I don't see any fix other than some shock mounting of some kind or other under the motors.
Or just simply leaving the machine as-is. Once the bottom shell is cracked, you can wiggle the motor and see that that's probably what the motor/prop installation "wants". 3 of my arms are cracked completely through and the 4th is just starting to crack. On mine, if the upper shell was going to start breaking it probably would have by now.
Obviously not worth the risk so mine will go in the bin, I guess. Or I might remove the innards and use the motors/ESCs/flight controller on an F450 or something like that.
I could exchange it but the new one will just crack too... |
