Haven't had the chance to fly my MCX in a couple of months. Got the urge tonight, installed new AA batteries in the charger and charged my lipo. I only got about 2-3 minutes of flight. When I tried to charge the battery again, the LED began faint rapid (1 per second) flashing after about 20 seconds. I tried to charge my other lipo and found the same thing. I rechecked that I had installed the AA's in the charger correctly and tried again with the same results. Anyone else run across this problem ?

thanks
Scott
