To clarify a bit, you had asked about photo quality between the cameras. Yeah, the cameras are pretty much the same, but the gimbals are not, and it is not just about the 360 degree rotation. The pitch (tilt) of a CGo3 may not work on a TH. I'm not sure if that is universal for all TH and all CGo3, but pitch is very glitchy when I mount a CGo3 on my TH. I can kind of get it to work by messing with it, but it certainly isn't a straight out response to the tilt slider. I tried two ST16s and four CGo3s, but I only have one Typhoon H available. All cameras on both controllers had the same glitchy performance. CG03+ cameras work smoothly using either of the controllers when mounted on that same TH.
This might be an issue isolated to this particular Typhoon H. I don't know. If anyone else has used CGo3 on Typhoon H, it would be good to hear some other opinions.
