Been searching to find out exactly how many mW the Video TX is, but can't find any info on it. All the manual says is: Video transmission range - up to 1 mile (1.6km). Been getting a lot of choppy video on the ST16, trying to figure out why. Tried the CGO3 app (iOS) and it works, but only get about 25ft before I lose connection. Granted this is in my backyard, lots of wifi around. Anyone have any info on this VTX at all?
