Okay, I have a brand new in box Savage X 4.6 which I'm still contemplating selling because the nearest hobby shop is like 80 miles away. Anyway, so what batteries do I need. I have the fuel bottle, toolset, glowplug ignitor with charger. If I'm not mistaken all I need is fuel and a battery right? Sorry, I'm a newbie. From what I've read I think I need just AA batteries for the radio, and a hump pack with charger for the truck electronics??? Any help is greatly appreciated. Thanks...
