I'd like to thank you all for your supportive feedback. I've now taken my drone out again for a second flight, this time using an ND filter on my GoPro. Again, any feedback is greatly appreciated. Two questions I have are: How to improve the quality of the GoPro footage? Even when using the 4K setting, it doesn't appear to be 4K and is quite blurry when viewed on a 4K TV. Even in daylight the GoPro footage seems to be noisy, how do I stop this? Gear: phantom2, GoPro hero 4 black, black pearl monitor, immersionrc 5.8ghz 25mw, fat shark cp antennas, iOSD mini.
