Higher pinions = safer MMM's? Or no? Someone's lying....

lol, ok.

The amount of resistance depends on the setup. A low current setup won't be affected as much by battery resistance as a demanding one. Obviously, the lower the resistance, the better. Ideally, it should be 0 ohms.

You can get an idea of the effect that resistance has on a setup by playing with this little demo I made: http://scriptasylum.com/rc_speed/_vdrop.html
