I was trouble shooting vibes from my T-motor installed motors. Seems I have about 45 hours on them from when they were installed, give or take an hour. Not quite the recommended time to replace, 60 recommended by T-Motors, but I have bearings burning a hole on my work bench. So I have a project to perform over the next few weeks....yipee.
The vibes were distinctive through the power band. Basically felt it throughout the bird, even slightly to the gimbal/gopro. High frequency type of vibe, typical of a failing bearing, not what I had been accustom to from the T-Motors. Had noticed its influence on my videos over the last week.
Anyway decided to inspect further how the vibes were transmitting to the gimbal. With the motors running and the battery tray removed, I was able to feel the gimbal's data cable vibrate at the same resonant down to the connector....
I know many of you have said the data cable is a source of the vibe problem. I heard you loud and clear, but honestly I was not having any issue from it and never modified it from stock. Besides I was working the hdmi cable and the isolators angle for ridding vibes, which was not a waste of time. I humbly stand corrected regarding the data cable. The "S" curve I had on the data cable was somewhat effective, but not near enough it appears.
I was able to reduce the presently transmitted vibes by removing the heat shrink from both ends of the data cable along with the tie-wrap at the main board. I did leave on the mesh wire loom. Bam, could feel the vibes at the main board and the vibes dissipated as I moved along the cable to the connector attached to the gimbal....
So next move is to coerce a member to make me a new data cable with silicon wires... @pious_greek . But for now the video is fairly spectacular. Obviously removing the source of the vibration is very important, bearings and balancing of the motors and props. Possibly I'm finely done with vibes....
Will post a video this next week. Just wanted to share what I learned, that others already knew....Peace.
