Hello everybody,
I am planing on building my first quadcopter, for the same I am considering:
http://www.ebay.in/itm/Quadcopter-F450-Kit-4xBLDC-1000KV-Motor-4x-30A-Motor-Controller-4x-Propellor-/121978742900?hash=item1c667fe874:g:ReAAAOSwLs5XLNy2(OR)
http://www.ebay.in/itm/1400KV-Brushless-Motor-30A-ESC-1045-Propeller-Set-/121983640287?hash=item1c66caa2df:g:UvsAAOSwyjBW4wlb (X4)
Can you please help me out in choosing the KV rating of the motors, the frame I will build myself. The battery i will be using is a 1250mah, 20c at 11.1 V, I have 2 of these
1) Is it possible that if i balance charge all the cells to the exact same voltage that i can hook them up in parallel using a "Y" connector cable to help spread the batteries weight across the frame and also increase the flight time? (I am thinking that the output after paralleling them will be; voltage=11.1v and current=1250+1250=2500mah is this correct?)
2)What is the difference between using 1400KV and 1000KV motors?
3)What will be the difference in the flight times?
4)What is the most efficient combination of the above mentioned motors and props?
Any help is much appreciated.
(I apologize if there are any obvious or stupid questions i am just starting to build multi rotors)
