feigao 6xl or 3s of 8xl on 4s

thanks for your reply. makes sense (though I don't know what loaded kv is...)

but what if I have more than enough current avaliable, lets say 150amps constant and 230 amps burst. With 11.1V I would have > 1500w available and 2300w availabale in bursts...???

would the points you mentioned still matter?
