The difference will be in the voltage which can change your handling factor. ie jumps, cornering...
With this being said then:
1: no it wont. You changed the gearing factor which took away the voltage advantage you gained with the 3 cell. But it should run cooler. (I think)
2: No. Same as above.
Hope this makes since. I have been up for 38 hours so far.   |
Maybe I should have been more clear.
Yes, if you go from 2s to 3s on the same exact setup, runtime will be lower. Of course, the car will go faster as a result. But, if you only apply the throttle so it is as fast as the 2s setup, runtime will be about the same, minues any difference due to the added battery weight.
If you changed the motor so you get the same total rpm with 3s as you did with 2s, then runtime will go up. If you keep the same motor, go to 3s, but reduce gearing, runtime should go up. It's all a matter of the amount of work the motor is forced to do.
