@Arehead

I have been messing around and come to find out.  As soon as I plug the battery in, that ESC that is on the motor will not make the correct sounds.  I have plugged the same ESC in a different motor and come to find out it works great.  Then tried another ESC with the motor I think is bad and it started doing to the same thing.  I think the motor is bad.  Is there a way to check?

Thank you Aerhead. 

I think my first problem is the programming.  After calibration the radio and other things Do I need to upload that information to the APM?  If you haven't guessed this is my first.

If you have a motor that twitches it's caused by a bad connection in one of the three wires that are between the motor and the ESC.  Or the motor is bad or the ESC.  A bad connection is usually the cause.  If you give too much throttle while trying to start a twitching motor you have a bad ESC very quickly.

@Andrew,  thank you.  I was just wondering.  I haven't made it that far yet.  I am still trying to calibrate the ESC's and not having very good luck with that.  I am currently trying to setup manually.

Now I am not quite sure what has happen now.  I tried the calibration on the ESC's and now one of them fires up on low position and another just twitches.

@Bradley, there is a 4-wire connector that sends the PWM servo signals from the APM to the power distribution board, and the mapping to motors can be changed by re-soldering the leads from this connector to the correct spots on the power distribution board.  I made a mistake with that on my build at first, it is fairly easy when working on the board upside-down.

While it would be possible to change this mapping in software, it is best to correct the wire connections so that the standard software configuration can be used.

I have a question that should be pretty simple.  I am setting up the motors on my new 3dr quad.  If the motors are not in the right postion.  Like let say No.1 needs to be NO. 3.  How can I change this so that the mapping is correct?

I am going to order the ArduCopter Hexa KIT v1.0, Pre-Soldered Flight electronics kit with the larger motors and the 12" props. My question is this, should I add a BMP085 is a high-precision, ultra-low power barometric pressure sensor and a MB1200 XL-MaxSonar-EZ0 High Performance Ultrasonic Range Finder. I will be using this as a camera platform in the future once I become proficent at controlling the craft.I am also adding osd and fpv.Any comments would be helpful.

Thanks, dhauer

Can you fly around in a Altitude hold?  That way if your trying to learn then the ground doesn't become your enemy.

10-4.  Thanks.  I was asking because I have not yet recieved my battery for the quad and was going to use my power supply to do the calibrations of the motors and getting everything loaded.
