Does your Vision + beep four times, like the P2V, after the initial 'tune' when you power it up ? Mine doesn't just makes the startup tune then nothing. I googled some vision + videos including DJI's and in all of them the vision + makes the same start up noise sequence as the original vision - should i be concerned? Hopefully it's nothing major - had the unfortunate experience recently of dealing with DJI customer support. thanks phantom community !
