Heres a quick test I did today with Peau modded Go Pro 4 Black with 5.4mm lense + ND8 filter. Balanced props, hubs and balanced gimbal (added weights to side and back). Just colored in post. Captured @ 2.7K/60fps No post stabilization. I like the results so far.
thats pretty smooth, are you still running the stock HDMI cable? I have the ribbon now, but honestly think it is motors causing those micro vibrations. I may put my stock cable back
