This is the smallest lens hood for a GoPro Hero 3.
After making and testing the first iteration it became apparent that the original design was a bit overkill for use on a gimbal'd FPV setup. This is smaller, lighter and more compact than the original design. It still can act as a sail, so keep an eye on wind speed (though it's much less of a problem).
As always, the darker matter material will work better.
I have received word that there may be some fitment issues. Ensure a snug fit before any prolonged flight.
