  My bet after not thinking about it very much is that you have it in X mode instead of Plus mode.  You can change this in the CLI using the setup, frame command.

  Adli: Did you double-check EVERYTHING on the Troubleshooting Page?

   

  And have you done the hand test as instructed in the manual?

  Chris: I double checked everything on the troubleshooting page. Blades mounted correctly. Maybe if you can see this video, you will know. https://www.youtube.com/watch?v=4BNWlOvHC2A. Thanks.

  Adli: Go through the Troubleshooting Guide. If that doesn't fix the issue, post a full report of the issues, including what you've already checked, hardware/software versions, etc. in the main discussion forum. BTW, if the props are spinning but the copter won't rise, you probably have the props on backwards.

  Hi all. I need help. I just cannot get my Arducopter to take off. I tried all the calibrations there is in Wiki but didn't work. I'm using FUTABA 6EX for the radio.

  Thanks, i did not realise there was a wiki page about the sparkfun module, thaks for sharing, I was also looking and it seems like the orientation is the same of both DIYD, and sparkfun :)

  Alex,

       I haven't verified but you should be able to make the Sparkfun Magnetometer HMC5883L work it's just a bit more painful than with the DIYDrones one.  In particular the sparkfun one is 3.3v so you'll need to use a level converter from DIYDrones or Sparkfun.

       There's an out-of-date wiki page here which shows how to wire up the older compass (HMC5843) and I think these instructions will still mostly work.

       Note that you'll need to test to see what orientation works with the APM code.  It'll be components down but no idea which of the 4 directions the pins will need to face so you'll have to figure that out by experimenting.

  Does anyone know if I can use the Sparkfun Magnetometer HMC5883L on APM?

  Marianne,

   

       No, they are a bit out of date (sorry, I'll update the wiki).  Note that if you load your code from the AP_MissionPlanner you'll get the right values.  Here are the best PID values for a Trex450.

   

  // roll
  #define STABILIZE_ROLL_P 0.70
  #define STABILIZE_ROLL_I 0.025
  #define STABILIZE_ROLL_D 0.04
  #define STABILIZE_ROLL_IMAX 7

  // pitch
  #define STABILIZE_PITCH_P 0.70
  #define STABILIZE_PITCH_I 0.025
  #define STABILIZE_PITCH_D 0.04
  #define STABILIZE_PITCH_IMAX 7

  // yaw stabilise
  #define STABILIZE_YAW_P  1.4
  #define STABILIZE_YAW_I  0.02
  #define STABILIZE_YAW_D  0.0

   

  // throttle
  #define THROTTLE_P 0.075
  #define THROTTLE_I 0.001
  #define THROTTLE_D 0.100
  #define THROTTLE_IMAX 100

   

       By the way, for questions/comments on the TradHeli, I think you should put them in this discussion.  This is where we have the most trad heli people.  http://www.diydrones.com/forum/topics/600-size-heli
