  • Hi all. Other than reading code line-by-line is there a manual/hierarchy of the ArduCopter code? How about a manual for the ports of the APM 2.5 and how to address them? My goal is to gut down lots of the code and I'd like to get closer to understanding how the whole code works, yet there seems to be very little literature on this.

    I'm also looking for someone who wishes to partner up, I have a lot of academic background and ideas I'd like to apply, share and implement.

    Warm regards,


  • I created an APM2.5 & DX6i flight mode settings post in my blog RCG

    it should help anyone setting up the radio and gcs

  • I will await the arrival.  Until then maybe I can make my mini arcade machine.

  • At Bradley and Chris, I really need to cross over to the other side. I also have a PI and been wanting to get a ArduCopter flying. Time to make that leap. Thanks, just the motivation I need.

    Bradley: We've already got MAVelous running Rasperry Pi, generating a HTML GCS over WiFi. Stay tuned for a product based on this soon. 

  • I have a Raspberry PI sitting here infront of me and would like to know if you think using this to control the Mission planner and contolling the copter would be good?  I have never done anything with the PI but maybe loading the linux OS, Then I wouldn't have to thave my laptop with me.

  • Thanks for the link.

    Point taken. I'll do it next time.



  • and heres arducopter help related for gimbals


    you dont need it to start, but when you are more experienced flying maybe as it just adds more to break learning

Drone flying to non visible point

Hi there,I encountered a problem, while flying in auto mode, with approching to point that was not set by trajectory and is not visible after downloading mission from flight controller by Mission Planner. Does anybody encountered similar problem. The situation is that in the middle flight I stopped the UAV and uploaded new mission and after changing to auto mode it starts to fly in some direction. It goes straight to some point, so I assume it's not mechanical problem. I attached the link to…

Will AHRS_ORIENTATION=8 for Arducopter 3.2.1 on APM 2.5 using a traditional Heli

I have been Reading Chris Olsen posts and watching his videos on Arducopter with traditional Helis using a Pixhawk.I have inherited an older Trex 450 heli with the old Align 3G FBL hardware.  The FBL controller appears to be bad.  So I have an old APM 2.5 without a compass or GPS on board.  I just want to replace the failed Align 3G FBL system with the APM.Now I have to mount the APM under the skids on the heli so the APM will be upside down.I have Two questions.1)  Is the AHRS_ORIENTATION=8…
