fix an issue with VTX functionality doesn't work on FCv1/CC ???
unify pro HV goes sometimes back to "lock" state when changing lipo.
Need to unlock vtx manual with the 25sec hold button to unlock it before smartaudio works again and all freqs are unlocked again.
Have this on 2 quads, next what i am going to do is remove FC and solder vtx smartaudio to crossfire channel 4 (set to smartaudio) to see if problem still occurs
