I have owned this product for about 3 months now (Phantom 3 Standard), and now one of the motors on it is failing. I know the reasoning for this. It's because I used to have the prop guards on it for safety, but when I removed them, I screwed in the long screws on the motors. Only one motor failed though. So now, I am looking for a new motor online to replace it, but I can't find any information regarding the Standard, only for pro and advanced. So my question is: which motor should I buy (remember that I have the phantom 3 STANDARD)? The following motors are available on the DJI Spare Parts page: 2312A (CW), 231A (CCW), 2312 (CW), 2312 (CCW). Any help would be greatly appreciated! Thanks!
