Not a lot you can do to upgrade it really I think, it's pretty limited by it's size.
There are plenty of other Micro and sub-micro copters out there.
Next step up is a more fully fledged quad but that can get pricey.
Those with an Inspire 1 and P3P (and possibly Advanced), have you seen the app Dronepan?? It will take 20 pictures from the height you set, and when finished you can stitch them together with your favourite software.
There's a closed facebook page (if you're on it), just request to join - https://www.facebook.com/groups/dronepan/
Its for IOS an Android beta.

Just a shame its raining for the next few days

Does anyone have a good website/resource that can teach me about batteries, C ratings, Amps etc.
I have a emax nighthawk 250 arriving today and need to order a second battery - It is confusing the hell out of me at the moment - I kind of get it but then theres some aspects I don't!
I know we should go by the max amps of the motors, so for the emax 2204's, I have a max amps of 46a, assuming Im using 6030 props. I take it its best to plan for 6030 props, if I switch to 5030 at some point, I can without worry.
Anyways, from my calculations, it seems a 25-50c battery is best. However I have been supplied with my kit a 60c battery, capable of nearly double that in burst, I think at least 100c burst.
Then different C ratings depend on mah too, and after this I get lost...
Then when using a battery that has a much higher C rating than required, what does that mean or accomplish?
It'd be awesome if there was some sort of table to help you pick what you need!!

I'll give you a brief run down.
The C rating of the battery is the discharge rate that the battery can deliver as a multiple of its capacity.
So, a 1C battery that's 1000mAh can discharge at 1A.
A 10C battery that's 2000mAh can discharge at 20A.
It's a good idea to have a battery that can discharge in the middle of it's C rating. So, if you need say 60A then you want a battery that can discharge at around 120A to give you headroom. For a 5000mAh battery, this would be 24C battery. For a 1000mAh battery you would need 120C to get the same discharge current.
The only effect of running a battery with a higher discharge rate than you need is weight. High C cells tend to be heavier. Running a battery with too low rating can cause brown-outs or worse, cause the battery to become very hot.

Ok - so you obviously know how to calculate the maximum demand of your power consumption. There's a thrust test here if you want to delve a little deeper into your motors capabilities.
The maximum amps the battery can deliver is (the capacity in Ah) * (C rating)
So a 1500mah 25c Battery will deliver a maximum continuous discharge of: 1.5*25 = 37.5a
As long as the continuous discharge is above what you need for your motor/prop combo you should be ok.
Some things to bear in mind though.....
1) The C rating of a battery isn't always an honest representation of what it's capable of. I have some 25c batteries that definitely don't keep up as they should. The voltage sags massively under load meaning less power available.
2) A higher, over specced, C rating tends to mean that the battery will keep delivering under high drain situations like punch outs. but......
3) Higher C rated batteries weigh more - so you have to balance that against the thrust available from the motors. No point in running a 150c battery if you only need 25.
If this is your first quad, I wouldn't worry too much. It's unlikely that you will be stressing the batteries as you are unlikely to be running at high throttle for large amounts of time.
Any batteries around or above 35c and between 1300mah and 1800mah will be best for you I think. There won't be a massive amount of difference in flight time as the extra weight of the larger batteries will mean a higher power draw.
Get a few though. You will only get around 5 or 6 minutes flight time per battery at the maximum.
Finally, not sure if your kit comes with one or if the flight controller is set up with a buzzer but if it doesn't - get a lipo alarm. It will stop you over discharging the batteries and knackering them. Don't fly them until the quad drops out of the sky, it will shorten their life very quickly.

Sure, if they have got a congested area permission for the flight in question.
Dont you have to notifiy the neighbouring property that you are flying within 50m though?
Expense crash anyway

Had my Phantom 3 Pro about a month now and loving it (first quadcopte i've owned).
Still lots to learn when it comes to shooting and editing video but here is a couple of videos i've done over the last few weeks testing it out.

Picking up a tarot 680pro this weekend comes with naza v2 and osd 8x 4s 6000mah battery's a t2d gimbal a spare complete frame and an 8xr receiver probably won't get chance fly for another week but will give me a chance research on the naza fc
T'would be fairly difficult to canvas an entire neighbourhood for permission on the off chance your I1 went rogue and crashed.
He will have had insurance, that's peanuts compared to the cost of bothering with CAA congested permits etc..
The media love to make massive deals about drone crashes, similar damage problem gets done on an hourly basis with cricket or golf balls etc..
Have you flown anything before? Might be able to give more help with Ann idea of your ability/experience.
Have a look around on the net. Flitetest and some other sites have some beginners guides but really it's just practice, lots of practice.
Flying fpv is easier for some than line of sight. I learnt the other way around. Mostly just flying figure of eights.
