Inspire camera lens thread size?

[delirious]

I purchased some ND/polarizing filters. Pricey. I'd like to find a reducing ring to put them on my phantom 3 instead of forking over more money. Anyone know the camera thread size in the inspire? I think the phantom 3 is 30

As far as I understand, that would be outside the capabilities of the Gimbal and the camera would tumble forwards with the extra weight, just a few grams is enough.

37mm, but with non-standard thread pitch. The P3 doesn't have a filter thread at all that I know of.
