ESC calibration

Hi I am following the instruction from https://code.google.com/p/arducopter/wiki/AC2_ESC from setting all the way to ESC calibration and everything went well until the calibration part.

I tried calibrating the motor and it managed to arm but after that it couldn't proceed to step 7 (Unplug the battery again and then reconnect. Now arm the APM with right rudder/low throttle for 4 secs, release rudder and then all your motors should spin if given a little throttle). I've tried both right rudder/no throttle and right rudder/ low throttle but to no avail. 

Any solution? Thanks!

  • I'm the newest noob on the forum (1st post), so I can't comment directly on the cause of your problem. However, if it is not a result of poor connections, you will soon encounter problems that are. Your first picture shows a number of cold solder joints that will compromise the reliability of your machine. In particular, note the black wire at the 3:00 position (far right). The solder has not flowed out to completely cover the pad, and looks like a bubble surrounding the end of the wire. Cold solder joints figure prominently in many failures I have read about on this site.

    You should start by 'tinning' each pad and the end of each wire with a small amount of solder before attempting to connect the wire, making sure the solder flows smoothly over the pad and is absorbed into the wire. Then place the soldering iron tip in contact with both the wire and the pad while adding additional solder. You know you have a good connection when you see the glob of melted solder 'slump' and fill in all gaps smoothly. The red wire at the 4:00 position is probably the best joint on the board, as you can tell by the smooth appearance. It is possible that your soldering iron is not of sufficient wattage to handle these large connections. Check out some of the YouTube soldering tutorials.

    Good Luck
