Note that the motors I'm using are slower than the motors normally used. That's why I want to try higher voltage. The higher V range and the largest pinion set I have should give scale speed.
As I build this winter, I'll post the motor/gearbox/battery info.
Higher battery voltage does not mean faster speed.
These electronics have voltage regulators built in so the battery voltage is reduced before any motor controls are processed.
I use 8.4 V in the Leopard and King Hauler models with no issues (and no faster motors either).
