Hello, I was just running my firestorm and the truck dosent yet have a filsafe so it was driving its self at a walking speed without receiveing any connection to the transmitter. The batteries I have bought last nigh and driven it for 3 tanks. Today I ran 3 tanks also and on the last tank it seemed that the batteries were low/dead. The servoes are slow also. the batteries were enegizer AA. Could they be dead already? And y?

Thanks in advance!
