Great job!
I think you will go through several attempts to mount your camera better - it is a new tangent to the DF hobby. As for eliminating the high frequency vibration issue - I think I have done that successfully. I haven't been able to fly outdoors in over a month do to our strange winter weather - raining, above average temps and when it clears it drops to -15C and windy as heck. I have been flying indoors only.
Here is a video showing anti-vibration at work in my setup
http://vssi.ca/dfvideo/DFV_novibe.wmv . It has been edit through windows to reduce size only - no other processes (I left the full 80Mb file in the directory as well). I don't think you will see any vibration (lots of crappy flying but - the room I'm flying in is 12x12 and has the curtains of death on the right side).
