What are you guys using in your Jato's?
im using the stock battery pack with four aa's strapped to the front shock tower using a velcro strap from my laptop charger.
what my buddies use:
5cell flat pack
1. Team Orion 1400mah 6V NiMH
2. Venom 6v 1600mAh 5-Cell Flat Receiver NiMH
Tamiya nitrage 5.2
the stock flat pack from traxxas works great
