  You just did.  It's hard to tell if a motor is bad by using an ohm meter because their resistance is so low.  If you know that the ESC you tested it with is good and all three wire have a good connection then the motor is not good if it doesn't work.

  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.

  @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.

  @Bradley, If I am not mistaken the dip switches are no longer used.  They used to be used for enabling camera functions, etc.  They are now user definable in the code.  The 5V comes from the ESCs', which is relayed through the PDB.

  @marco, thanks very good to know :) keen to see some comparisons in terms of vibrations (i.e. how good the bearings are) and thrust..

  @Anish: as you can see also the table of characteristics is the same, changing only the outer bell:

  @Anish: i use Tiger Motors 700kv on my heavy X8, this one (SunnySky is the company who makes them for the TM):

  They are made very well, excellent bearings mounted, I would say that the quality exceeds even that of Pulso.

  Gerry, i haven't found nothing about this, I've buyed a good hdmi-composite converter, is not very heavy if you remove it from the case in which is contained:

  @jani would it be possible to publish test results, would be keen to see those
