First off let me say that this drone ,P4P, has the best options in the market. That being said, I'm on my third one. I think I am jinxed. I thought I hit pay dirt with this one. Even did the firmware update and flew 4 or 5 times , perfect! Then yesterday I was recording a sunset just hovering for about 15 minutes, no wind. I noticed the video was jerking around a bit like jello. I brought it down and shut it off. Went inside and started it back up and now I have vibration in the gimbal that is causing it to be unstable. Did several gimbal calibrations that didn't help. It sounds like the motor is rubbing on something. A metallic sound. I hate to send it back, but I feel if you pay $1500 for something it needs to work correctly. It's not like I'm not familiar with flying. I flew a Yuneec quad for 4 years, and have flown full scale airplanes and jets for 20 years. I love the quad,I just wish I could get a good one. Anyone have any ideas? Serious thought only, leave out the sarcasm.
