So I'm trying to get some jello free video with my H-quad, and am wondering what is it that I need to do.
I'm using the FT H-Quad design that I'm sure many of you are familiar with. It has 1/2" square booms, and a 3"X17" or so, piece of light ply on the top and bottom, with the ESC's inside. The lower, removable piece of ply, has a "tongue" sticking out in the front, about 1-1/2" for the camera.
I tried mounting my GoPro directly on the tongue with Velcro, then using a battery strap to secure it more. Lots of jello.
I understood that the vibrations are traveling from the props and motors, directly to the beams, directly to the ply... And the only thing insulating the vibrations for the camera was Velcro. Understandable.
So then I put Velcro on a piece of foam, to add some more spongey... And a piece where the back of the camera touches the wood. Still jello-ey... That's a word right?
Then I started thinking. What if took a 3"x 5" piece of light ply, mounted the camera to the front of it, with some thicker double sided tape, (a little spongey ness right there) then put some foam, about 3"x 4" of it on the back of the ply, removed the tongue, and stuck it under the frame. Then I used rubber medical tubing, with long zip ties through the tube to loosely hold it to the frame.
I figured then there is no direct contact between the frame and the plywood.
The camera is very loose and wiggles easily with your finger. I worried about it being too loose though.
I also thought that maybe the foam was too soft, so I cut some strips in the foam and layer in some of that same surgical tubing to act as kind of a dual rate suspension for it.
It still gets jello.
Now before you ask... No I haven't balanced the motors and probably could do a better job balancing the props but let's say I did... Would something like this be suitable for jello free video, or am I missing a key ingredient in this recipie for disaster?
Other than using a gimbal, what's the trick?
Should I lose the zip ties and use bolts to connect the tubing like I've seen before?
Harder foam like neoprene?
Softer foam?
A combination of foam densities?
Wire and rubber bands with air between the frame and camera mount?
Forget about all that junk and just balance the props and motors.
Here's some videos of what I've done. The first one was using the tongue, the second one was with the lower camera mount described above.
