4S will require a pretty stout ESC. I have been testing a couple larger 39" riggers on 6-7 and 8S. KV from 1100-1600, 40X92 to 40X100mm motors. On 6S a TP 4060 (92mm) 1350kv (4Y) and a 200 amp Castle with props from 2115-2219 pull 180 to 240 amps and mid 70's. 8S and a 1250 kv will put you in the low 80's. I have tested with a 300 Swordfish but it is a brick heavy and large. The Flier 250 is lighter and stout 8S capable. 4S batteries in series make 8S and I have plenty from P/limited use. To run 6 laps stay lower on prop and or KV's. Many ways to skin the cat here depending on your goals.
Thank you I picked up a 1620 kv and a 6s 130amp and if not enough I'm upgrading to 8s 200amp and 1200KV,I'm starting small on prop and going to read temps I was told I would need a 1/4 " cable if I want a bigger can and more power with stepdown shaft to 3/16
