Noob question. I have patiently gone through all the set up, had to re-solder a couple of ESC bullets. But now when I plug the Lipo in one of my motors is twitching and beeping continuously. So I have soldered the ESC and motor leads but it still twitches and beeps.
Any ideas anyone?
I had the same problem.
Use CLI to get it work.
Calibrate the ESCs during the cli session and activate the magnetometer. This helped me a lot.
If all else fails I'll have to do as you say and try new ESC's.
I'm using a Turnigy 9x altered from mode 1 to mode 2.
here are the results from U command.

No previous experience what so ever.
Thanks for all your help
I am having similar problems, I am using ArduCopter Kit ESC and motors.
Been through CLI, tried ArduCopter and ArduPirates code.
Changed Motors, changed ESC. My rear channel seems screwed, last resort I've got a new APM on the way.
your problem sounds a bit different to Ken's ( his transmitter/receiver channels are mixed up).
What do you mean by rear channel - do you mean rear motor? and what is up with it?
I think its the channel (output 4) that drive the rear motor, as when the rear ESC is connected to the front, left, or right channel outputs, the motor functions fine.
Under ArduPirates NG code the rear motor has a mind of its own, under ArduCopter NG code, the motor worked perfectly during the motor test initially, then when I switched to flight mode, the all motors just responded to throttle, then the rear stopped, then after power cycling, all motors work fine, except rear won't start.
Today, I swaped out the rear ESC, and the quad is working, roll/pitch/yaw numbers NOTgoing crazy with the sonar disconnected. Flight successful.
Only issue is my original isssue, ESC needs to be connected to Output 5 instead of the standard Output 4. Connected to output four I either get no response, no startup, or this happens http://www.youtube.com/watch?v=KLZhXtUhFAA
Next flight, the numbers are all screwed up again.
That's really good data and makes it easy to see the problem which is straight forward.
It looks like Yaw(Rudder) on your transmitter (left stick right/left) is connected into channel 5 on your APM (fifth value along on that serial output). It should be coming through on channel 3 (third one along on the serial output).
The ArduCopter is looking for minimum throttle and maximum yaw to arm the motor - the way your reciever is connected to APM it looks like it will never see that.
Can you swap channel 5 on you receiver for channel 3 and see if that lets you arm. If that is not clear let me know and give me a picture of how your receiver is connected to the APM.
It also looks like some of the other channels may need reversed but that is easy and you can look at that once you manage to arm.
I think you're nearly there - in case I forget - make sure that your first flight is on Stable mode with GPS off.
I had the same problem with just one motor/esc, the other 3 boot up just fine. The 4th motor boots up with the others with their usual set of beeps, but then it gets stuck beeping forever and will not power up when I arm the other motors they spin up but the 4th does not. I re-calibrated that ESC manually, and it seemed to help for a while, but now it's back doing it again. Sometimes if I let it beep for a long time it will eventually stop beeping and give me the two beep done signal, then it works. But I'm guessing it's just a bad ESC. I'm going to replace all my ESC's. Any one have a good recommendation? I'm thinking of switching to these Turnigy 25A ESCs, any one know if that will be compatible with the rest of my Arducopter kit?
