Greetings all, I have about 150 flights in on my P3P. Today I noticed that the two motor arms on the back (straddling the battery) appear to twist when I apply pressure that seems consistent with hard maneuvers like active braking or in high winds (not much, perhaps a millimeter). The front two arms seem rock solid. I confirmed that it wasn't the motor bolts/mount (they are tight, but not too tight). The motors don't seem like they're at risk of pulling off, they just twist more than the front two. Am I just noticing "the way it is" or is there something I need to tighten down internally? I don't see any loose bolts on the exterior shell, and don't want to void my warranty. Thanks!
