I was using the dvr in the goggles (older spectrum box) but yes, the image quality on those is great for the price I think.
Of those two AIO cameras, I cant see any difference in quality or performance. I just prefer the one with a selectable power setting.
If I'm just throwing it on a model to mess with, like my UMX timber, and I'm running it on a little 280mah 1s velcroed to the top of the plane, I will set it to medium power. It doesn't get as hot and lasts way longer, maybe 5 times longer than the battery in the plane I'm flying. On that plane in the video I'm using one of the esc's to power the camera so I dont have to use a separate battery. When I do it that way I leave it on high (200mw)
Just another side note, I prefer box goggles. Some people just never get the fat shark style to feel right, I'm one of them...
