    @john. Your HiTec will be perfect. If you want to buy a new TX though wait for the Taranis from FrSky. It uses Open9x firmware so is awesome for drone use. And it's only $200!
  • Glad to be part of the group. On the brink of ordering a loaded quad from udrones.com however I want to use my Hitec Aurora radio is there anything i should be aware of? Or should I just order a TH9x for it and be done with it.

    Re, "where are we with ArduCopter 3.0", we're at release candidate #2 now which you can find here.  There was a temporary problem with the downloads area so initially I could only put rc2 into the old downloads area.  Anyway, the new wiki is the place to get it.

  • http://ardupilot.com/downloads

    the version 3 is listed there (rc1)

  • Just wondering when is the Arducopter 3.0 release scheduled?

    From the git log I can see that 3.0rc2 milestone has already been reached.

  • Thanks Randy for saving me a bunch of time - I didn't realize till your reply that I could change parameters from the Advanced Parameter List thinking it was only a listing of explanations.  Dumb me.

    @Jim,

         Re where to find the ACRO_P parameter.  You can find it in the Mission planner's Configuration, Advanced Parameter List.

  • Where do I find Acro_P to make adjustments per the Wiki?  It is documented in the parameter listing and Wiki but I cannot find where to actually adjust it. 

    The APM does acrobatics.  WOW!  I'm thinking I need to increase the Acro_P to increase the rate of roll and pitch.

  • Hello Remus,

    I am doing the same work as you. There is no manual about the structure of ArduCopter but the code is very well commented.

    Howerver, the structure of the program is easy to understand and will not take more than one week to be fully understood.

    Start by the Arduino References to learn basics.

    Arducotper code is written in C programming language. I advice you to start by reading the ArduCopter sketchbook and figure out which operations the program perform and at which rate.

    Then, read the files defines.h , config.h , parameters.h and parameters.ino

    They will help you to master all parameters of the ArduCopter program (Parameters are very important if you want to make code improvements compatible with Mission Planner, I advice you to read the AP_Var lib in the AP_Common lib).

    After, it is up to you to follow de lines from ArduCopter.ino to get a better knowledge of some arducopter functionnalities you want to improve.

    Best regards,

    Guillaume Braibant

    PS :

    I apologize for english / spelling mistakes but it is not my native tongue (French) and I do not have much time now to correct my message.

  • Might be best for you to start small with the arduino site

    if you can grasp that then your on your way

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…
