ok so the motor im looking at is max 120A (turnigy 2560kv), then if i got for the 150A esc, and change the batteries to 5000mah 4s 45c should give me 225A, would that be better? this has a much higher ampage but with it only being 5000 not 6000 will that effect run times much? also do you think i can make it quick with this setup?
