Default 3s power

I am running a Scx10 ll with stock esc and motor with a 300in oz servo. I am happy with using 2s batteries as far as power and low speed control. What would I gain by switching to 3s ?

More power and speed.
First check that your ESC can support 3S.
And in order to keep things safe and cool it is recomendable that you reduce the size of the motor pinion.

As the Holmes Hobbies motto goes:

"Volt Up, Gear Down!"

A great side effect - if you use, for example, a 3S 3300mAh LiPo compared to a 2S 3300mAh LiPo, you can also GAIN runtime at the same speed!

I know this is unpopular, but Ive personally decided to stay on 2s. There is more than enough wheelspeed, about a jogging pace, and plenty torque for the rocks I run. BUT I started rock crawling having 4 2s high capacity batteries. If I was starting fresh I would definitely recommend 3s, though you will break more parts that way. 2s is not as horrible as some make it out to be, it has plenty of power and can still be great fun. As long as you are going lipo instead of nimh you will be fine.

One advantage to 3 cells, (and the reason I run 3 cells in all my RC planes), if you gear them both for the same top speed, you can get the same performance with lower cost (lower C rated) 3 cell packs vs 2 cell packs.....

I vote yes for 3S

You're going to gain power and speed.
