also, would using C batteries be a bad idea? they supply more current at the same voltage, so would this increase range?
thanks!
*edit: come on pros, im lookin at you spanky, chelboed, anyone...

C cells have more current capacity, meaning they will last longer. Given the same voltage, the current will be the same; the load dictates this. Increasing the voltage with a given load will increase the current.
I would not recommend going above three cells. Also, if you want to increase the battery life put the same number of cells in parallel. For example,
+cell- --- +cell- --- +cell-

+cell- --- +cell- --- +cell-

Some alegbra ... V=I*R (voltage equals current times resistance).
