Yea i thought of that i may go that way in the spring time as it's cold here now and i can't run the boats to much longer....and that brings up another thing the water was 54degrees so maybe this is why my electrics and motor ran so cool and the batteries got a little hot....Mybe in the summer things will really heat up?
On another note the 3300KV motor on 7.2V was 20.000rpm now on 11.1 3s it's 30.500rpm that made a big differance.
