The DJI support said they cannot be changed, but I call BS on this one. Isn't the mounts and screws the same to install a Zenmuse and my own FPV setup?
Will work if you can get a 2.4Ghz transmitter and reciever for the video. Most are 5.8Ghz which the Vision range use for control. It had been done. Use the custom site search link in the General Forum Stickies. You should find detailed discussions on the subject. If you have more questions just bump the existing threads...keeps it neat.
