You may have to do similar to me, gear for a touch under 40, and have a ~6000mAh 6S pack to get 20 minutes.

Yes I have less potential power but I am dropping the kv of the motor and increasing the voltage which will mean I am going to be pulling a lot less current out of the batteries. I am currently geared for 2250kv motor on 4s for 33.8mph but the 1550kv motor on 6s will be 35mph on the same gearing and at the higher voltage it will be running cooler as well due to the lower current draw of lower power motor and the use of higher voltage. Well the only real way to see is to put it into the car and give it a go. I have nothing to loose!
