I ordered the timer with the alarm this morning. Thanks for your suggestion. I thought maybe that that feature might be on some kind of software that came with the cell phone app that one uses to watch from the camera on the plane. If there is not such a thing, someone ought to write an app for it.Joesrevolution said:Hi there n4lb welcome to the hobby! If you're anything like me your bank ballance will hate you as with the batterys for the fc40 of you are not weighing your phantom down with anything extra such s an extra battery/ go pro you should be able to get 12 mins out of the battery. Although if you're unsure 10 mins is a good time to bring it home. To time this you can always set a timer on your phone or invest in a timer for the transmitter. http://www.ebay.co.uk/itm/like/28124725 ... 0&ff14=108 the other option if you don't plan on going long range is put a lipo allarm on the battery which will make a loud been when the battery falls below a set level. You should be able to hear this over the sound of the motors provided it is not too far away. You can get smart allarms and battery checkers built into each other llike this one which I use. https://www.google.co.uk/shopping/produ ... CFMQpiswAA these are particually useful when you have more than one battery where it can be hard to keep track on which is the charged battery. This particular checker also acts as a programmeable alarm with a very loud buzzer which you can see in the bottom half of the pack. Hope this clears things up a bit. If you have anymore questions feel free to inbox me!

The smart bit means that it knows what battery you have plugged in too so there's no calibration necessary. The only thing you need to set is the low voltage setting that you want to go for. See the pic below for both of these points

Of course it won't warn you, and a battery monitor would be best, but I have found it a good way to keep track of things.
