I apologize if this has topic has already been covered. I'm wondering if there is a aftermarket conversion to change reciever to a AA battery setup. Not sure if AA will have enough power for all the servos on the revo 3.3 . I'm not sure if maybe I have a bad battery pack. The truck is only a day old. The battery maybe lasted 40 minutes of runtime total. My Tmaxx batteries last hours in the truck before needing to be replaced. Is short battery life a common issue for the Revo 3.3?
