Hi Gents, We have been having high frequency vibration problems in some aspects of our footage. It is not all the time and does not occur at specific times when the copter is flown in a certain way. It is frequent enough to ruin most shots. We have tried a number of things but are now running out of ideas. I will run through what we have been through but any further suggestions would be greatly appreciated. We have been mostly flying in windy conditions, but I do not think this is the problem because when I had the copter hovering just a foot off the ground juddering around in its own prop wash the footage was flawless, like the monitor was on pause, despite the airframe and electronics working very hard! Very impressive, but why does it struggle at other times? Our rig is a Cinestar 8 HL with Wookong M gear powered by 2 6s flight packs. Underneath is a Movi MR carrying a C300. We have worked hard on the balancing issues and understand the concepts behind it all. The camera sits at any angle you choose to put it and tilting the Gimbal does not cause any rotation, indicating a well-balanced gimbal. Our initial gimbal settings were: Pan: 80 Roll: 70 Tilt: 60 These were obtained by one of us holding the gimbal in the air while the other dialled the numbers. Once problems were noted we changed these settings to the following: Pan: 65 Roll: 65 Tilt: 50 This lower set of figures give a completely smooth gimbal suspended by hands, whereas the ones above show a little vibration in the hands, but actually seem to give better results in the air. (I am not sure how to adjust stiffness for airborne as I think suspending the rig in a frame or by rope will not be a good substitute for flying conditions. Instructions, as noted by Angus Benson-Blair are very thin on the ground for flying when compared to handheld.) Throughout our filters in the advanced settings have remained at: Gyro Filter: 5 Output Filter: 5 I have no idea if this is normal or not – there is no reference! We have tried to be methodical and scientific changing one thing at a time… we were initially using the harder vibration dampers (green and white dots) and now have 4 green and white and 4 softer red and white. We changed them because we thought the others too hard which might possible cause the transmission of the high frequency vibration. We also rebalanced the props for a second time. We have not done the motors yet (Tiger MN4014 Kv400’s). We also went over the whole airframe checking all bolts. Please see the video clip below, Password: vibrations https://vimeo.com/87608380 The beach and the windmill are using the harder dampers and the clock tower is with the softer dampers. Although this clip is cut to show the worst bits, there are clearly lovely smooth bits too. That is why we are so confused! Any suggestions would be greatly appreciated as we have some great ideas for our show reel but no way of putting them into action yet! Thanks very much for taking the time to read such a long spiel!
