  Good evening,

  I don't see a 2.8.1 parameter file for the 3DR ArduCopter Quad-C in the download section. Is it available?

  Thank you
  Randy

  @Altaf re how to use user_hooks,

      I've never personally used it but it looks like you should put your code into UserCode.pde and UserVariables.h.  I guess it depends very much on what you want but the userhook_50Hz function in UserCode.pde will be called at 50hz.  Just make sure it all completes within 5ms to ensure that you don't interfere with the main loop which runs at 100hz.

  So has anybody managed to get the APM 2.5 working with Turnigy Trust esc's or do I need to return to the APM 1 ?

  @Zachary, can you explain a bit more what you plan to do and on which axis

  Updating to 2.7.3 erased eeprom hence this radio calibration. Updating to earlier firmwares left eeprom so no calibration was needed. Anyway, I just wrote what helped me in similar situation. You can try (it takes no more than a minute) or wait for other hints.

  Zachary: did you do radio calibration after uploading new firmware? I forgot about it and had the same effect as you described.

  @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.

  @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.

  @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.
