Electrical problem??

[nitrostarter]

Ok, so I bought a Hitec 3-Ch Aggressor radio. Ran it for the first time with the new BL system, flipped over and messed up the antenna wire so I threw the stock TQ3 back in. Everything was working fine for a while. Then my steering servo quit working. I thought it was a low RX pack so I charge it back up. After 2-3 runs on the fresh charge the steering servo quit working again. I unplugged the RX Pack wire and plugged it back in and the servo worked fine. This keep up for a while and I just keep recharging the Rx pack. Well today the servo quit working completely, even if I unplugged the RX pack and then plugged it back in again. By the way the servo is a Hitec 645mg. Also the shifting servo would perform flawlessly throughout all of this.

What do you guys think my problem is? The RX pack or the servo? or possibly the reciever.
