Here are a few simple questions for all you experts:

1. In a stock e-maxx, I just purchased and installed a 625MG steering servo, is it running at 4.8 or 6.0 volts?
2. I want to turn my stick packs into side by side packs. What is the best way to get the "tin" strips that connect the batteries together? Heating does not really work. Should I just take a pair of pliers, and pull them off?
3. What is a lighter alternative to the stock wheels and rims for bashing?

As usual, thanks in advance for all your help.
