I don't know if this will help or not but I'll offer anyway. I have not had any detectable issues with vibration causing video problems on the M600 until I mounted an Olympus 45mm lens using the X5. I think getting all the gimbals to balance is very important with any lens greater than the 12mm or 15mm. I did a test 6 months ago after mounting a new 25mm on an Inspire 1 Pro and could detect a small amount of jello in the video especially when sitting still. The gimbals were not well balanced so I corrected that issue and the video became stable, lesson learned. The 25mm is my favorite lens. If you are using a 45mm lens everything needs to be balanced because it will magnify any imbalance you have. I went out to the local airport a few weeks ago and was testing the 45mm. When I got home and viewed the footage I was not happy. Bad shaky video that was unusable. Luckily I just happen to have a new Garmin Vird 30 mounted on the bottom rear plate pointing forward at the X5. Sure enough you can see the X5 dancing like crazy which explained the bad video. The camera wasn't moving all the time and seemed to have a rhythm or a resonance to it, kind of hard to explain. I thought about what could be causing the issue because I already had 40+ hours on the bird with no issues, at least any that I could detect, and several hours with the 45mm. I started looking at my props for damage, something that could cause an out of balance situation but found none. The one thing I did notice, there were several props on different arms that seemed very tight. Don't know why or what could have caused this, maybe dust or a change in humidity and temperature that day. There is no way to adjust or measure how tight the screws are and you can’t use a torque wrench so this is what I did and it seemed to work. I point the arms straight down in their storage position first. Then unfold the props parallel to the floor. Release the props and observe what they do. I loosened them just enough to allow them to fall slowly at the same time. Seems like this is a good way to match them together. I know it’s not scientific but it seemed like it could work. Bottom line is that it did work. I do not have any more problems. I think that I had one or more props on different arms that had become tight and could not completely extend. If this happens, especially on different arms, I could see why there was intermittent vibrations. This could be why some people have been flying for many hours without issues and then suddenly one day, as I did, the issues begin. I didn't try this but you could mix up the props and reinstall to see if the vibrations change. You need to be careful using this method for obvious reasons. Of course you could buy or borrow a high end scale and weigh each prop. I tried taking the prop hubs off the motors and balancing the hub and props together but I'm not convinced that will work becasue you need to be able to perfectly extend the props before balancing. I hope this can help someone. |
