With all of the "Stress Cracks" threads out there, I hate to make a new one but I've read thru a ton of them and I haven't noticed anyone crashing their P3 because of it. I have small cracks on both back arms and I am tempted to just use the zip tie method around the arms. So I'll ask the question here... Will these cracks let the motor fall out or let the shell separate to the point that a crash results? If this is an inappropriate thread because it's been answered already, then I apologize and a mod can delete this thread. Thanks.
