Default "Wavy" video on Dig cam

my wife bought me one of those $29 "Worlds smallest DV" camera's... not much bigger than a pack of wrigleys! Today was the first day with decent weather so I thought I would try it out!
it takes suprisingly good video just carrying it around, so I was looking forward to the flight video.
When I played it back it almost looks like it has electrical interference... as soon as the heli starts to spool up, the video gets "wavy" and distorted; as I spool up the waviness speeds up and vice versa. Any way to correct this?
I have it mounted to the nose of a scrapper canopy on a 1" square piece of 1/4 inch gel then ziptied for security... but again, it looks more like electrical interference than vibration. with it mounted to the nose, it is only about 2" from the ESC.
I would post it, but I dont have any decent editing software to cut it down from the full 5 min almost 300mb clip...

That's what you call 'jello'.

It happens when vibrations get to your 'Cmos' chip based cameras - which those small spy cams have.

You can mimic the same effect by hand, or by strapping it to something that vibrates.

It's really hard for these low quality cmos chips to get vibration free images from something like an rc heli - but the best way to minimize it is to isolate the camera from the vibrations the heli produce.

I never have liked jello...

so I guess I need to first minimize absolutely every possible heli vibration that I can, then come up with a better "isolating" mount. What are some good options? any one have anything that "works"?
