I've read a lot about P2V/P3P/A having issues with their shells developing stress cracks. I haven't had any problems with it *yet*, but have been getting worried that it might eventually happen to my P3S. A theory that I've heard is that the screws were over torqued during assembly. Some people have suggested loosening and retightening all the screws, but I don't want to mess with it unless I have to. I've heard of the UAVBits Strong Arm kit, but again I'd rather not have to use it. So have the cracking issues been resolved by now? If not, what can/should I do to prevent it?
