Found my error. Seems you can only change which aircraft you are in is when you are in a "gunner position. This was driving me
while I was setting up "Voice Attack" to take care of all my key board commands. Now, as an example, all I have to do is say gunner 2, then another command, "plane 2, plane 3 or plane 1.
Now the only thing I have to figure out is how to voice the message I want to put into the radio channels 1 through 4 and get them to save and print into the radio buffer. I have got the radio buffer to open, but not copy the text yet
