Hi phantomas.....
i have not had time to read all of your guide but i'am very impressed with what you have done with it.. here is my contribution that i would like to see in your guide or not but feel this information alot of people wont know about and will in certain situation come in very handy for them.
......return to home feature...fail safe.... as we know if fail safe is activated your quad will RISE to 20 meters or pre-set amount and return to 'home point' which was set. What i didn't realize was that if your phantom was flying above the rth set height lets say 50 meters and fail safe was activated it would not descend to 20 meters and return to home, in fact it would just return to home at that height . This is a great feature to know about in case you have walked past some really high trees or building, and if you are not sure how high they are or what your pre-set rth is and you lost orientation of quad or lost nearly sight of it just hit full throttle so it rises into the sky above all dangerous obstacles then hit rth it will travel at the height as long as its above the set limit or put it into home lock either way helps

..... when updating your phantoms firmware it decides to go crazy and make the loudest beeping noise, which sounds like an internal error has happened and you immediately want to turn it off. i feel this should be mentioned that its part of the update and not to panic like me lol. i went crazy and thought i had destroyed my phantom. Also i didn't know when your connection has been lost while updating your phantom, it will go into pause mode. the beeping sound may be activated but it will actually pause its update on the phantom it self not on your pc so no damage is done (i dont think). all you got to do is then reconnect the cable and it will continue to update. Just don't turn the phantom off completely while doing this process.,
when i update my phantoms firmware my usb disconnects all the time. it doesn't when updating say the battery of other features just the main firmware of the phantom. i don't know if this happens to anyone else., and my phantom makes that god awful beeping sound like its about to explode. well all i do is unplug from pc and re plug back in and it will finish updating it and then just power cycle your phantom.
i feel these two points re-worded to your magic should be mention and are great to know about (just in case it crops up)
