I tried a polarizer filter but it didn't really help. But when I tried an ND filter the jello is suddenly gone. Finally! Haven't flown in really windy conditions yet but I'm encouraged.

Yes.

There in no "hoping" involved. An ND filter will eliminate jello because it forces the GoPro to use a slower shutter speed.
This has been well-documented for a long time.

An ND filter does not always eliminate jello. The frequency of the vibration, the ND filter rating, and the amount of sunlight on that given day will all determine how effective the ND filter is. All an ND filter does is reduces the amount of light that reaches the CMOS. When the reduced amount of light is detected, the GoPro reacts by slowing down the rolling shutter to compensate for the decrease in light...if the amount by which the shutter has been slowed allows for the vibration to pass before the CMOS commits the image to memory then the jello will be eliminated; if the day is particularly bright or the vibration's frequency causes it to intersect with the new shutter speed...jello will still occur.
This too has been well documented. There are plenty of reports of mixed success with just trying an ND filter, which is why I chose not to "hope" an ND filter would fix my issue. I haven't even mentioned the other side effects such as the impact of an ND filter in a low light scenario. If you are flying like I am strictly to get the best quality footage possible, then you only use an ND filter when it will improve the footage; not to hide problems with your setup.
