Do the 5 cell hump packs fit under the fuel tank in place of the aa batteries, or under the truck in the other batt. holder? i thought the one under was for flat packs. im not sure tho. i have some 2500mah aa batteries but only 4 and they are 1.2volts so only 4.8 volts total to the servos. not sure if thats good or not.
