V2 UPDATE ! <<<<<<<
So after some testing on my quad I notice some optical refractions caused by the layer in between the gopro and the ND filter. So I moved the ND Filter closer to the Gopro to avoid this kind of issues.
I didn't find any gopro mount that fit well the ND filter TBS without scratching it so I made one ;). Made for TBS Jello guard ND filter, with an immortal T mount on top, you just need to lock the antenna with zipties.
Enjoy feel free to comment
