I'm still not happy with the H3-3D Zenmuse. I was filming and randomly there is a twitch when the GoPro flicks upwards it only happens occasionally but can spoil the film. Today when running the motors no props and testing the FPV setup with a new antenna, as I powered everything down I noticed one of the Zenmuse motors was significantly hotter than the other. The hot one is on the camera horizontal arm. I. Take it this isn't normal or does one typically run hotter than the other. If the motor is on the way out can I buy a replacement? Nothing immediate showed up in Google when I looked.
