To be noted adaptor ring set is not included in the above. So, you'll have to make adjustments for it.

Also, ordering radios from international warehouses is a hassle. Batteries at times, but other parts usually come without a problem. Just ordering 4 motors will be no problem at all.

Hi ratul,
2200mAh will give you around 5-7 minute flying time. It depend actually on the weight. Minimum is the weight more is the flight time. Because, if your quad would take off at 60-70% throttle that means for keeping it in air you need to give atleast that much continuously. So, that will eat up your battery. If you can keep the AUW(all up weight) somewhere around 900-1200 gm then you can go for a 3300mAh too. It would give around 10 min. flight time.

I really want to get the 3300mah battery if possible. I think that its weight is nearly 150gm. By my calculations, if the total weight of the model is below 800gm, then I can get a 3300mah battery.

What are spacer rings?
Do these propellers work with CF 2822? And also, what is the approximate thrust generated (by all the four motors)?

I will order 4 EMAX CF2822 from Rcbazaar. And I am also looking forward to get a 3300mah if the weight is below 800gm.

I just used the Drive Calculator (a program used to calculate thrust, flight time, etc) with the same motor and a 8*4.5 prop. The battery is a 3300mah battery. Here are the results:

8*4.5 need to be spinning fast to provide thrust, bigger props and lower kv motors will be more efficient. Also, with those motors, there will be no point of the 3300mah battery.
Let me give you an example:
With 8*4.5 props and a 2200mah battery, my quad hovers at slightly above half throttle and gives me 5 minutes of flight.
With 10*4.5 props and 2200mah battery, my quad hovers at slightly below half throttle and gives me 8 minutes of flight.
With 10*4.5 props and a 4000mah battery, my quad hovers at above half throttle and gives 10 minutes of flight.

The links for the batteries I used are below:

http://hobbyking.com/hobbyking/store/__9185__Turnigy_4000mAh_3S_20C_Lipo_Pack.html

Comparing the prices, the 4000 is 3 times more expensive than the 2200 but gives me only 2 minutes extra.
I'd rather buy 3 2200 batteries in the price of one 4000.

You need bigger motors to be able to lift heavier weight, because these small motors are not very efficient with big props after half throttle.

A friend of mine running these motors: (http://hobbyking.com/hobbyking/store/__25082__NTM_Prop_Drive_28_26_1000KV_235W_short_shaft_version_.html)
with 10*4.5 props gets 15 minutes on the same 4000 battery.

Would the flight times be the same with CF2822, or are you using a different motor, and so the flight times would be completely different. By the way, I have decided to use 8*4.5 propellers with CF2822.

why do you think you need 8*4.5 better get 10*4.5

No, I am running these motors:
http://www.quadkopters.com/product/221213-1000kv-brushless-outrunner-motor-with-mount/

I can't say whether you'll get the same flight times or not, because it varies from motor to motor. Also, props are not very hard to change, so if you don't like 8" or 10" you can always switch them, without much hassle.

The CF2822 will not be very efficient if your quad is heavy and thus flight times will fall. Try to keep your All Up Flying weight within 1kg and these motors should be fine. As I have already stated before, a bigger battery doesn't always mean better flight times, because a bigger battery also means more weight, so take care of that. If you can keep the All-Up-Weight with a 3300mah below 1kg, then you should get about 10 minutes flight time.

The bigger the props, usually, the more stable your quad will be. You will have to experiment with props to find out which are the most efficient on your motor and battery setup and suit your flying style the best.
The most common sizes of props are 8x4.5, 9x4.5 and 10x4.5.

I would still suggest going with 9" or 10" rather than 8" props.
