Motors - Hmm

This is how I have my battery packs wired. Like I said I noticed slight speed increase when I connected the second battery... but... also added weight from a second battery pack.

I'm using two 3000mah packs. I don't see how a single 3300mah battery would make much of a difference. I am still wondering if they're fully charged or not. runtime is still very short. I am almost ready to recycle the aluminum and go back to stock plastic! LOL!

Anyone who can suggest an engine/battery combo that will bring my rustler back to the speed it once possessed while still being aluminum will be my hero.
