I think I've asked for help about this before but couldn't remember. On my Phantom 4 I've noticed that 1 motor runs a little hotter than the other 3. Around 5 degrees hotter at the most. I used a ir temp gun and even though I know it's not especially accurate for displaying accurate temps but it's saying that 3 motors are 90-92 degrees Fahrenheit and the one in question is around 95-97 degrees Fahrenheit. It feels exactly the same as the others when I spin in. So I'm not sure what's up. Can anyone give me some insight as to what might be happening? Thank you in advanced . I appreciate it.
