So you need a few things to do that but it is possible. First on YouTube, someone put up a video that has the startup for all the birds. It was a mashup but it comes from DJI commercials. You need to snag the audio from that video. There are several YouTube to MP3 converters online you can use for free, just do a search. Once you have that, then you need an audio editor. I use Adobe Audition, but there are some free ones online as well, or you can use a ringtone maker. Then from there you just do some simple editing and some copy and paste so you get a repeat of the tone and then save it to a ringtone. I know I take a lot of assumptions that you know how to do all that but YouTube is your friend! I am no mechanic but I rebuilt the transmission in my Jeep once by watching YouTube videos, and it is still going strong.
