My quadcopter is V type frame.

Motors Emax 2213 / 935KV / 1045 props

Slightly soft props, not much like phantom but they are not rigid

4000 Mah 3s Lipo

APM 2.6

total weight of quad copter = 1600 grams

giving only 9 ~ 10 mins in a no wind condition and mostly loiter / hover

How can i increase my flight time (i cannot reduce the weight more) ??

suggest me motor / prop upgrades .

Thanks

Move to a 4s battery, get lower Kv motors, increase prop size, optimize lift target for 1.15x weight at the most efficient arc for your motor/prop combo.

  Dear Michael
  
  Thank you for replying, can you please explain this in little detail

Obviously it will need to be retuned, and be no where near as acrobatic, but it depends on what you are after....

Depends on the largest size of props your frame will handle, if you can get 15" props on, then swap your motors to 350-500 kv pancake motors, and double your batteries up, you will get at least 20mins....
