Default Vibration issue with Video

I bought one of the 808 key chain cam's and I have serious vibration issues with filming. I changed all for rotors and inspected all the carbon shafts. I did noticed 3 of the 4 thruster booms seemed more fragile when twisted from side to side. Pulled all 4 out and didn't noticed any cracks. Any ideas?


Thanks

Balance anything that spins, and try to vibration isolate the camera. This is difficult as the camera doesn't have that much mass, and thus is harder to damp. You could strap the main battery to the camera, and try and isolate the two of them. The battery would add more mass, making it more resistant to movement.
I'm currently waiting on a similar cam, I'll let you know how mine turns out.

I currently have the camera stuck with velcro underneath the battery tray. Should I move it to the top of the canopy or try another fastening method?

Again, it's about isolation. The camera has little mass compared to the quad as a whole. Putting it on the canopy won't help. Combining the mass of the battery and camera gives you more of a chance. Velcro is not bad, but there are foam gyro mounting tapes that will do better. I have used rubber iso mounts in larger quads they look like rubber donuts. Mcmaster carr has several kinds.

Issue solved. I decided to use a zip tie to help fasten it down more. It worked!
