Motor mount cracks 1 by lake_flyer posted Mar 31, 2015 at 10:50 AM Motor mount cracks 2 by lake_flyer posted Mar 31, 2015 at 10:50 AM Motor mount cracks 3 by lake_flyer posted Mar 31, 2015 at 10:50 AM Might as well check your Phantom for cracks every once in a while..... I always tried to figure out why I couldn't get rid of a annoying vibration in at least one of the motors. Ever since I had the P2 I had this tiny vibration in my shots and no matter what I did with dampening, calibrating or changing gains, it stayed. Suddenly, just now(!), I noticed these cracks in 2 of the motor mounts. I have opened the P2 only once before and didn't notice anything back then. But it is clear now that at least one of the motors has a bit of play because of the cracks. Now I noticed this, I wonder if they were there all the time? It looks like the screws have been screwed too tight, or the shell had not been aligned correctly when they closed it up in the factory. And maybe they spotted it then and corrected it but the damage was done anyway. Who knows, this bird hasn't crashed one single time, always landed without tipping, never anything odd. Had already a lot of experience with flying, opening and closing the FC40, so I'm not a newbie who is likely to screw up a screw job himself. I think it is grounded, don't you think? Need a new shell, dammit! There goes another 55Euro's and a few weeks waiting and a few hours of rebuilding (kind of like that though).
