Towerpro Mag 8 ESC help

I just got two of THESE brushless combos from UH with the Mag 8 20A ESC's. I soldered the motors and battery connectors on and plugged the first one in. It gives the arming beep, but the motor won't spin. I soldered the other one together the exact same way, and it works fine. I swapped the motors, and both motors work ok. Both ESC's beep the same, just one won't spin the motor. Can the ESC be fried even if it still beeps properly? I was testing with a 2S battery, could this ESC be set for 3S? I've red the programming threads but am baffled by them as my beeps don't seem to match what the charts in the threads say. Any help would be greatly appreciated. Thanks.

You're not alone. First mag8 worked fine for 5 flights powering big red cf2822 that works and makes good power. Last flight heard the motor making strange sounds and landed. Ground tested a little, swapped motors, still had strange noises with stuttering. Swapped another mag 8 and no rotation at all. All the beeps were there. Tried a known gbl single and nothing.But the beeps were there. Tried a 3rd mag 8 and now back to normal. good luck

ive got the same problem, ive figured the motor does not spin up because of lipo cutoff because mine starts with 3s and sits still with 2s !

But the sounds are not as described in the forum posts from 2006 ! they changed.. *lol*

Cheers !
