Gutted! 6 weeks in & another crack thread!

Me too.

Structurally, this looks to be caused by the screws being tightened. And, if there is a solid plate on the other side of the plastic, then it is, at this time, mostly cosmetic.

Have any people had a flight failure they can pin on such a crack in the plastic?

With some background in aviation (as an aerial photographer, but one who was always inquisitive), this kind of crack would be a major concern to a manned aircraft. But for a 3 pound quad... I am thinking there is little real world risk here. But, I do not know for sure what is on the inside of that piece of plastic that the 4 screws dig into. If it is solid metal... I think it is no big deal.

National no plate inside screws go straight to bottom of motor,,you can get proper plates to go on,,not sure link have to Google unless someone got pic of one,,,if clever you can make some,,alloy sheet cut to shape 4 holes and away,,,,

Then there is likely very little chance that this gets much worse or that it results in a loss of something. The motor body is metal. It is going to keep the plastic right where it is, IMHO.

The top photo looks like the integrity could be compromised. If the crack was only between the holes then the motor will be the support and it is stronger than the plastic to start with. But, once it gets outside of the motor structure... could be trouble.

Just fly! Don't worry about the crack until you notice it in flight.

I a little risky but would rather repair just to be safe,,another reason not to fly around houses ,,if something should happen there going to be damage,,bit lucky I have others for back up while I fix it,,,
