    Default Motor wires being so small

    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.

    You really can't change the motor wires.....go to 5.5 or 6 mm bullets...and on that hull you should be fine....Start on a smaller prop...and work up ...if you can....watch the temps..on ESC ...motor..and batts....

    These are 4s motors. I don't think the rotors would last any length of time on 6s.

    You might find some of this interesting.. https://forums.offshoreelectrics.com...5-1500Kv/page2

    If you run on 4s and fit some 6mm bullets all should be fine. we run the low kv aquacraft motors in our limited class racing and nothing gets warm whatsoever.
