I would say that a 3S lipo in the range of 3000-5000 mah would be OK. I say 3S not 4S only because of the high kv motors you are using. Personally with this setup I would have gone no higher than 700 kv. Also, you may find that your motors may get quite hot and you'll have to drop down to 8" motors. BTW you don't have to bombard this forum with a copy & paste of the same question on every single thread, we heard you the first time

Geez, that nearly 2 pounds in weight and almost 2 feet in diameter. What exactly are you planning to use a quadcopter that size for?

A quad that size would be good for aerial photography and would actually still be pretty sporty to fly. It's not really that big

 

[Aamir khan]

My purpose of making quad is just for photography .
But still if u think i need to change things in it so plz let me know size motors esc any thing plz tell me

 

[Aamir khan]

Ooki i will go for battery 3 s 4200 mh
Weigt of battery is 306 gm now the total weight of ma quad is 1106
So the weigt is good or i have do some more changes

Here's a good tool for testing your setup. It will tell you if it will work and what kind or flight times you can expect.

If it were me, instead of trying to be Thomas Edison and figure out how to build one that might not be reliable, I would get a Phantom 3 or 4 and load it with a Go Pro Camera. Sounds like the amount your investing in money and time in the build would just about cover the cost of a Phantom 3 with Go Pro Camera. But then, that's just me. I buy them, and fly them and feel safer doing that.

What's the fun in that?

 

[LoneRCRanger]

Well, my extent of technology regarding quadcopters ends at loading the battery, pairing, launching and crashing into the nearest tree. With that in mind, I probably would not buy a $1,200.00 Quadcopter just to crash it into a tree. I am one of those people who should be hired to conduct durability levels of quadcopters.

Hello one of ma friend told me to go for 980 kv motors with9047 prophelers
Is tht advice is correct for more time in air
