I thought this was odd when I took it out of the box the other day. I've been flying about 20 flights now and it flies good however lot of vibration on the craft. I figured it could be the firmware but got to thinking I recall one motor sits lower than the other 3. Pictures and video is great but the gimble is doing the work. Anyone else see this on their craft? If I turn the blades no matter what the one motor sits lower. The one blade is lower no matter which way I turn the one blade.
