Sure thing Upper, here's one more link and may be the most important. If for no other reason than battery level, an OSD of some sort is critical to FPV flight. All the other things it shows, like number of satellites acquired, distance to home, altitude, lat/long, elapsed flight time, and a few others, are really nice when flying. Just remember, the info is there to be used, so it won't help you if you don't use it, like what happened to me on my last flight with the crashed machine. The last telemetry I saw was the battery voltage of 10.1v, which is the secondary warning in NAZA Assistant, and at that voltage, it auto lands (or auto crashes as my buddy in NY says) no matter where it is.
So here's where I got my N1 NAZA OSD. It's US company and knocks off about two to three weeks of waiting for something on a slow boat from China. Prices are stable across vendors.

Now, here's the catch with the N1 OSD. Everything on the screen is in Chinese if you use the default screen. There are two other choices, the DJI screen, which looks similar to the iOSD-mini, and the Custom screen, which allows you to turn any icon on or off and allows you to position them anywhere on the screen. When using this screen, there are only two Chinese icons on the screen, one is latitude /longitude (which is such a large number, it's painfully obvious) and the other is altitude, if I remember correctly and it's easy to just remember one. There's one more drawback, NO USER MANUAL at all!
But not to worry, some dude has posted some extremely helpful videos online. The first two are a general installation and setup video, as well as a followup that shows the OSD in use by placing the Phantom in his truck and driving around. The third one is the charm though, as it shows how to get through all the Chinese programming menus to set your unit up. This is kind of overwhelming at first, but gets really simple and fun to use once you get your feet wet. So here are the videos:
this is the installation video
this is the follow up showing actual use of telemetry
this is the one translating Chinese instructions to English
These were priceless to me in getting my N1 OSD configured. The last one was just published on April 8 of this year, so I'm glad I didn't get one before then.
OK, have fun and ask questions AFTER researching and BEFORE buying to avoid some heartache and an empty wallet.
