Scale Soaring UK

Have a look at this.



If you have any ideas how I can mount the Mobius, to get rid of the shakes, I would be pleased to know.

This one was mounted rigidly, but I have tried rubber mounts, and taping lead to the camera to damp the vibration.

I have seem smooth video from a tug, so it must be possible.

Change from IC to electric?

Ahhh, The ever helpful Mr B...

Barry, have you seen these http://www.banggood.com/3D-Printed-Anti ... AmC58P8HAQ (hobbyking also do a similar one), might do what you need.

Yes, I might try one, but they are designed for Quad copters. These have High frequency, low amplitude vibration, where we have low frequency, high amplitude vibrations.

Sill we have to try everything.

Watching with interest as I now have a Mobius to play with. There are a father and son team who film a lot of the LMA shows including onboard footage and they produce top quality videos, I will try and find out how they do it.

Electric tug....about as much use as a chocolate fireguard if you want to tow more than a couple of times

PoD, Barry

The father and son team are the Coxon's and they attached their cameras to my Klemm at Elvington last year and got some great footage. All they did was to put sticky backed velcro onto the model and use this to attach the cameras. Seemed to work fine and after filming I could pull the velcro off with ease.
There is a video on youtube of the flight, search 1/2 scale Klemm.

Pat, the electric suggestion was very tongue in cheek as I never for a moment thought it would be a contender for Barry
I hope you find a suitable mount Barry, but suspect that something suitable for a single cylinder powered model is likely to be a little harder than for John's Klemm as that has a lot more cylinders, making the vibration model rather different.

I agree Peter. The airframe is a lot stiffer, and has more inertia to absorb the vibration. Also as you say, his nice 5 cylinder radial is much smoother that our singles, and twins, which both have only the one bang per revolution. Nice video though, and a nice display. It was good to watch, as I did play a very very small part in it's construction.

The quest for smooth video will continue.

So that's it then, just re-engine it with a radial

I could not afford the propeller, let alone the engine, but thanks for the idea.......

The videos the Coxon's make all use the same Mobius camera and velcro mount regardless of the model and engine. They have had good success even with single cylinder engined models. I think the trick is to get the normal self adhesive velcro which allows some minor movement and not the stronger stuff which is too rigid.
Also , where you mount it on the model will affect quality as it does need to be on a rigid part of the structure.
all the above assumes you have a balanced prop !!!!

Never mind the Satanic Vibrator, Pat... stick the Mobius on your Petrel

I shall do that as well Chris but thought it would be nice to do some from the tugs as well.

Very little vibration from the Mobius on my video, Pat. https://vimeo.com/76270815

The electric porter video was a lot more stable, but still had some vibration coming through.

I love the Red strobe though! where did you get that from and can you show us how you set it up.

We tow at our local small airport that is reasonably active with full size planes. a strobe would add to our visibility.

Stuart - yes a little bit of jello, but a lot less than some.

There's not much setting up to be done, just connect up and apply power! I will add though that I don't feel they add much to the visibility of the model on a bright day. If you really want to make the model more visible, take a look at the other offerings from Emcotec, particularly the white LEDs.

The Americans call this effect "Jello" so if you enter "Anti jello mount" into your favorite search engine you come up with hundreds of answers to your problem. I use the two pieces of plywood fastened together with cable ties method plus anti-vibration grommets fixing the mounting to a third piece of ply which Velcros to the airframe. The Mobius is also fastened with Velcro and the whole thing hangs down under the airframe. The Velcro is the blue self adhesive thick stuff from HK. I think having it hanging helps, if you get my meaning! You have to rotate the camera image 180 degrees of course. I also recommend a safety strap from airframe to camera as Velcro unaccountably lets go after a short sharp shock.

Thanks for that tip Richard. Having looked on Amazon ( other websites are available ) under anti jello mount I found some anti vibration mounts that can be incorporated into something I am making up. Lots of the cheap stuff comes from China via carrier pigeon in around a month but there were some UK suppliers at a very reasonable price.
