I just switched from phantom to naza and i thought that the beeps when i start the phantom would be *** usual, just that in naza mode it would do three extra beeps. So when i start the phantom in naza mode it sounds exactly the same when i start it, there is no extra beeps. Is that normal? from videos ive seen theres always three extre beeps in naza mode. Is it three extra beeps only on phantom 2 (non vision)? Thanks in advance.
