This is our first demo of our unit. We ended up doing a few gold courses too. Super fun to do and the hole by hole fly-by with Pro-tips was a hit.
Here is mine i'm still working on building it. ( its waterproof and floats the airframe i bought from aquacopter - took about 3+ months wait time )
3d designed and Printed a new lid for it.
3d designed and Printed a wire holder and battery mount.
I will probably run two batteries in parallel.
Hope to finish the lid and get all the electronics buttoned up and fly this thing soon.

Is that pic one guy to pilot it and seven to supervise?
I need to get get one or two of these for patrols. Need something with good range and long battery life. Also need to take min 5 megapixel stills. Hardest thing to find is long range and batt life.

Greater than 5 M pixels isn't a problem but what sort of battery length you talking about? Greater than 20 minutes?
I would like a batt that is good for 45-60 mins with a flying range of 1-2 kms. What is the longest lasting batt now? What about range?
Check RCGroups there is some guys that post trying to build the longest flying multirotors. Some have got over an hour but they are all custom built and built only for long battery life. They are not carrying anything extra to save weight.
I doubt your going to get anything anywhere near that long with a camera on it. Range is farther than you can see it. i think First person view range is close to a mile depending on your setup.
20 min might be possible.
I finished mine this weekend, still need to build a gopro mount and landing gear. I'm lucky to get 5 minutes on mine. 10 if I run two batteries. I'm restricted on space. Also at some point if you keep adding bigger batteries your flight time will get worse due to weight.
Yeah absolutely. More or bigger batteries hampers more than helps. Been there.
The best we have with pinpoint accuracy is line of sight with can be 1.5km range and we have let it live past 25 minutes. But when the batteries get low, even tho they aren't supposed to, strange things happen. We've needed to track her via GPS a few times after she went crazy and disappeared on us.

That's not good !! I need the best of both worlds...long flight time....good pics while hovering and zooming in....long range with POV, don't really need to see the copter...and return home function so I don't lose it when it is out of sight or batts run low. Its for work so time is money.
Seems to me that these devices should have an "Auto return before battery runs out" feature.
I would think with todays electronics, these devices could be made to return to the take off point automatically when the battery drain rate gets to the point where it might not make it back without a microprocessor decision to send it back.
You have GPS which tells the unit how far it is away from the take off point. You could have a battery drain rate monitor in the electronics. Then you could have a microprocessor to do calculations based upon how far away the unit is from the take off point and compare that to the rate of drain, and make an automatic decision to fly the unit back with specified margin of safety before the battery depletes before making it back.
That way you can use 95% of the battery life without having to guess that you might/might not be able to fly the unit back in time.
The scuba industry has been doing this on its dive computers for more than a decade (Signaling a diver to return to the surface given how long, how deep, and how fast he/she is burning though the air tank(s))
Thoughts?

I thought they did (DJI Phantom) or is the auto return only if it fly's out of range from the controller?
Im not sure about the DJI Phantom but I have the DJI Naza M Light flight controller in my custom build. I'm pretty sure I can program it to give warning light when battery is low and program it to land immediately when the battery gets even lower ( both thresholds are settable ). I'm not sure if it can be set to return to home though, i think it will just land where its at. There are custom flight control boards that are for the real hobby/tinkerer that you can program them to do whatever you want. Quite a bit more complex than the regular store package units.
I just run a timer on my radio that beeps at me.
I have mine setup to return to home if it looses signal. I also hooked it to a switch on my radio for testing purposes. I tried it once and I wasn't confident in wtf it was doing so I flipped back into manual mode and landed myself.
