    Interesting stuff and that may well be the answer to being able to use my Canon Vixia on one of the multi's, I'll find out around the of March when it gets here. Should arrive shortly after the new mount from Avertical so I can put the two together and hang it all under the Hoverfly.

    Would be interesting to see what it does at different frequencies!

    Ken have you given up with the Photohigher mount?

    Mount thought!

    Just a quick one ... Ken you thought about separating the main body plates from the landing gear using some anti vibe mounts like the ones in the photo?

    Not at all, it lives under the Droidworx Hexa, I need something better than the HiSight II I currently have under the Hoverfly quad but I'm not going to spend PhotoHigher $ to do it. I think the multi axis standard they have at Avertical View is an interesting setup for not a whole lot of money as quad camera mounts go, plus I could get them to build it to my specs, even better! It's a bit of a lead time as each one is made to order but I can wait, still have two feet of snow on the ground and the HiSight is getting the job done for the time being with the Cannon SX 200 and GoPro. I'm hoping the new mount along with the vibration dampener will be just what the Vixia needs to work on a multi. So far I have not had much luck getting ANY camera with image stabilzation to work well on a multi. Cameras that have none seem to work just fine, so I'm still experimenting a bit to get the right solution so I can use either. If that solution works out to be I can use it on the Hoverfly but not the Hexa then that's the way it will be, if the dampener lets it work on both then that's the ultimate solution. As long as I come up with something that lets me fly it and get useable video, that's really all I'm concerned with.

    ken, you ordered a vibration damper from dave's first post? it'll be interesting to see how it works out.

    Yes it will. The idea seems sound, whether or not it will do what I need it to remains to be seen, but for $20 something it's pennys compared to what I've already shelled out :eek:

    If that doesn't pan out, I've got another idea that should though I'll have to wait till it warms up a bit so I can spend some time in the garage working on the mill to make it.

    vibrations are extremely complex and what works in a lab doesn't necessarily always translate to real world benefit. it will be very interesting to see if it does its intended job. kudos for doing the testing.

    Did anyone tried the rubber stand-offs that come with the MK? just an idea.

    I tried them on the HiSight II on the Hoverfly quad which is a Hexa frame modified to only have 4 arms, it actually made the vibration factor worse to the point where I started getting the jello effect on the GoPro where there was none before. Removing the mounts and adding some extra bracing across the frame to the center of the mount made it much better, so removing the ability to flex actually lessened the vibration as seen in the recorded video.

    In this case the mount is very light and narrow and putting a camera on it effectively turned it into a pendulum. Widening the mounting deadened the pendulum effect and removed a lot of visible vibration.

    No, but I have tried the blue Align gel pad material used for mounting gyros and other vibration sensitive devices on RC Heli's, didn't help the Vixia at all. This material is roughly 5mm thick as well and is a reuseable adhesive surface on either side of a soft rubbery silicon gel type material.

    Ive just ordered some to give it a whirl. I need a week off work to do all the testing I want to but I am back down on London again next week Yawn... I hate the place!

    crahs,
    what's the scheme to try with the foam? squishing it between the camera and mounting plate?

    I use the antivibration foam made for wrapping receivers in RC airplanes under the GoPro when I put it on the Hoverfly quad. The HiSight mount isn't tall enough to use the GoPro case so it has to ride naked on the platform. A layer of the white foam wrap under the GoPro with a velcro battery strap around it and the platform works well to keep the cam in place and reduce the amount of vibration that makes it through. It's not perfect, there's still a tiny bit of vibes that can be seen in the video occasionally but it works much better than just strapping the camera straight to the platform.

    On the Droidworx the GoPro case can be mounted to the Pro Mini paltform using the tripod mounting foot, I sandwich a 1/4 inch thick piece of silicon rubber RC exhaust tubing between the mounting foot and the platform and that seems to soak up the remaining vibes that make it to the mount. Tried the same thing with the Vixia and it didn't seem to help much if at all.

    Good question. I don't know. I've seen many different opinions on vibration isolation and I have yet to see one 'right' way to do it that works for everyone.

    In my opinion, the first step to reduce camera vibration is to balance the motors and props as perfectly as possible. I see a lot of people skipping that step.

    That's a good idea balancing the motors and props. OK I have a prop balancer and that is no problem, but how do you balance a motor with out a strobe light?

    Cheers
