Thanks for the prompt reply Dave. I'll give it a try.

Yes, adding weight helps. With a 5 pound camera on a Flyer, you'll want to add weight to the top.
Grab a pencil. Hold the pencil between the thumb and finger of one hand, and move with the other hand. Hold it in the middle. When you move the pencil, the eraser moves a lot. Now hold the pencil much closer to the eraser. When you move the pencil with your other hand, the eraser moves much less.
So in order to decrease the effect of movement on the lens, you want to get the gimbal closer to the lens. In order to keep a reasonable drop time (2-3 seconds), you will need to add weight to the stage (top) in order to move the gimbal closer to the stage. The best way to do this on a Flyer is to add a weight plate or practice cage. A velcro weight might also work, but be sure that it's absolutely secure, otherwise it will move around and throw off your balance.
Hope this helps.
