What kind of engines and propels should i buy?
 
Ok till now i have this:

-a nice frame (40 cm from one engine to other)
- 3S3P battery - 15.000 mah
-a total lbs of 2000 grams (actually 1800) but i already added the engines weight.


So what kind of engines and propellers do you suggest me for:

-fast speed
-to make it hover a very big time in the air?

How big is your battery?
2kg is way too much for 400 size quad.

The 3 battery is waving around 1200 grams. You think i should buy a bigger frame ?

Something is not right if the battery is 2/3rds the AUW of you quad. 15,000 mAh is more appropriate for an 800mm frame and some big motors I would think. I am going to be using 16,000 mAh on an 800 mm hexa with very powerful motors (3KG thrust each.)

By the way how much time do you think you could fly? Also from what a range can you see the quad by your eyes? 1 mile ?

Flight time should be around 3hours and 4.78 miles range ^_^

Are you building a b52 bomber?

Build plane if you want to do long range. I multirotors are not for distance flying
