5 cell Rc10b4?
 

If I keep the same motor but reduce the number of battery cells from six to five, how many teeth on the pinion gear should I gear up to?

I believe its two but dont quote me on that.

I don't know of any 'rule' about changing gearing when going down on batteries.

what are you trying to achieve by doing this?

it does seem that the people that are using 5 cell on low grip tracks go to a hotter wind of motor and run the 'right' gearing for that motor.

I do not re-gear my B4 when I use 5 cells.

Six minute mains, same motor temps as with 6 cells in 5 minute mains!

I run them as 3x2 with 3 full front and 2 a 1/2 pad from full rear.

No weights in rear of B4.

Two reasons that I hear,

1. Reduced weight.

2. Low grip tracks.

OK a 3rd reason :)

3. Lower cost >>> Thinking is if you build 5 cell, you have a extra battery and if you do five packs you have enough cells left for one more pack!!!! You get 6 packs instead of 5.

I stopped using 5 cell cause I had a ESC go bad, smoked the brakes, and the replacement ESC is a 6/7 cell only ESC.
