  @Randy
  THANKS. I was extremely worried that my programming could have created some problem with the power distribution and inadvertently fried the apm.
  
  But now, we realized that our NEW program allows the apm to function properly (i.e. board powers up, ESCs arm, motors respond to throttle input). However, uploading the regular ArduCopter 2.7.3, the motors stay in calibration mode (consistent beeping), regardless of what we do. Do you know why?
  
  

  As for ESC overheating, is it caused by malfunctioning power distribution?

  Thanks.

  @Zachary re frying board through errors in the arducopter program,

      I don't think that's possible.  For things like an ESC where you've got large voltages that are being controlled by the firmware it's possible but as for the arducopter software, it's just running a program that changes signal out to ESCs, xbees, etc so I can't imagine how that could happen.

  Is it possible to fry your apm board through errors in the arducopter program?

  @Lucas re obstacle avoidance,

      Somebody asked that same question on the sonar wiki earlier today, i guess it's a popular thing that people want.  We don't support that at the moment and no specific plans to add it although it wouldn't be too difficult.  People would have to buy at least 4 more sonars though..$120-ish..not terrible i guess.

  What are the features that can be realised for an Arducopter? 
  Are there something like obstacles avoidance?

  @Bradley re what is the pwm coming out of RX.  If you have your APM connected to the mission planner, go to the configuration screen, radio configuration screen and below or beside each of the green bars you will see the raw pwm value.

  Could somebody tell me what the PWM is coming out of a RX.  I don't have my scope anymore so I really don't have a way of telling.  I needed to see what the range is coming out of my futaba radio..

  Bonjour,

  une petite question: avec Mission Planner 1.2.11 comment avoir la fonction "Prefetch" ? le bouton a disparu!!

  Hmm, we've just received another bigger, heavier, more powerful quad. It was passed down to us from a couple of people who have flown it fine before.

  After re-assembling it, we tested it's flight. During rolling, the motors on the relevant side are supposed to power up to allow it to roll, however one does not do this. This is the same when rolling in either direction. Does anyone know a fix for this?

  Thanks. X)
