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 !!!!

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.
