Ok, Have aquired 2 Aquacraft motors 3656, 1800kv and 2030kv. Seams to me that the wiring coming out of the motors are small in dia. I use 6.5mm bullets (esc to motor). Both the 1800kv has little 2.5mm (maybe 3.0mm) attached. Just wondering if changing them to 6.5mm bullets (seams kinda small wires for the size bullet) will motor handle 6s? with a x645?? (maybe m445) Just wondering about the motor size wires heating up being so small.
Oh, and a 150a ESC in a MC29v3, batteries would be 2s series to make 4s, 5000mah 50c each

Hope I explained this well enough for you'all more knowledgeable than me to explain.
