Turnigy 80 plush? Arming?

[RVFR]

I just saw this category in this forum thought I might throw this out here as well.
I have a turnigy 80 plush on my Trex 500, it has been flying great for the last 6 months up till now, seems as though My battery came un plugged in flight , luck had it I wasn't that far off the ground 10' so it was just a flop ,nothing broke. Whew! it was when I walked up to it I saw that the battery plug had come lose, now I haven't turned off the TX, so I plugged the batt back in, only to get the feeling that it was to lose to fly it like that, so I admittedly un plugged it and put another battery in it's place, it was then I noticed it wasn't arming up, no beeps, I thought that was odd, so went and checked everything I could think of and still it's not arming up. I tried other batteries, shutting down the tx and starting over from scratch, doing all what i thought would solve this, Nope, is it a bad esc? the servos work. Any ideas here.
