Hu.. I do almost the identical thing, with the PVC tube and dowel.. I cut my dampeners by pushing the dowel through and using it as a cutting surface, as I roll the whole thing along the desk with the knife on top with one side of the blade up against the PCV pipe edge. Rubber tubes are used all over in industry for dampening. First time I saw them used was about 25 years back for dampening vibrations on a rail mounted injection molding system for GRP helicopter parts production. It's a great tool. Nice job with this application.
I've seen these on FlyBoySee's tri and they work very well. I've always used silicon tubing on my Tri, but never quite got the right inner/outer thicknesses. Although I'm suspending the battery/GoPro on them, as opposed to having the weight sitting on them. It's ok for normal flying, but the wind can cause wobble. Do you think the suspension technique works with them ok ?
Ah yes I remember sending FlyBoySee a set last year. Most mounts will work better under compression, these in particular become more stable with increased weight, they flatten out and their contact area increases. They can work well in tension, but with increasing tensile force they stretch and become less stable, to counteract this you can use more mounts or space them further apart. A wider footprint on the attachment points makes a huge difference. Also you can allow them to butt up against frame parts giving them some lateral stability as in the Ycopter 350 design.

For camera gimbals I like two or more rows of three dampeners, with the middle one perpendicular to the others. It seems to reduce wobble a good bit if they don't all fave the same way. . currently I have 8 tube sections like the one in the video, suspending my gopro gimbal.. I've set them up in a square... I have all four corners with the tube at 45 degrees and the side of the tube facing out. Then tube sections between each corner (the sides of the square layout) have the tube openings all facing out from the center. In the middle I have a proper gimbal mount dampener.. essentially another tube with varying wall thicknesses, standing on end in the center. It's as stable and jello free as I've ever made. :D

***** Hello itchy robot, your camera mount sounds interesting, can you share a photo or video showing the mount?
Sure.. I'll post some on my channel later this week.
this is a great idea
Very nice work...good thinking.
Thanks, some more interesting flying videos are in the pipeline...
Brilliant.
Brilliant !
