I am struggling with finding a set of parameter descriptions/ instructions that match those that are in my version of Mission Planner. I am using 1.3.5 build 1.1.5260.33055.

I am finding references to lots of parameters that simply do not exist in this version of Mission Planner. For example - starting at the very top of the list of Standard Parameters shown on this website:

http://copter.ardupilot.com/wiki/standard-parameter-list/#APM_Mission_Planner_Standard_Params

there is the parameter called ARMING_CHECK, but there is no such parameter in the MP Full Parameter List. Another example: CIRCLE_RATE. It's listed on the site, but doesn't exist in MP.

Since both the website and my version of MP are fairly up to date I really would like to know what I am missing here. Is there another list of parameters somewhere in MP?

Since I'm writing, maybe someone can help with this setting in particular. I had to invoke RTL a few days ago because I lost sight of my quad while it was on an auto flight plan and I lost my nerve. It took a long time, but finally there was my quad chugging along towards "home". What took so long is that it was flying backward, and it was only going a few feet at a time then sort of loitering, then moving a few more feet. Had I gone further away before invoking RTL it might have drained the battery before coming back into view.

On this website: http://copter.ardupilot.com/wiki/rtl-mode/ it says I can set the quad to turn to face toward home for RTL by setting WP_YAW_BEHAVIOR to 1. Problem is, I can't find WP_YAW_BEHAVIOR in the MP parameter list! And, even if it's flying backward toward home, why would it keep stopping and starting?

Sorry so many Q??s but I can't seem to find relevant answers anywhere.

    Parameters exist in the vehicle code, not the GCS code.  Some parameters listed above may not exist in the version of the code you have loaded onto your vehicle.

    • Sorry, but what is the vehicle code, and what is the GCS code?

      • Developer

        The vehicle code is Arducopter.  The GCS or Ground Control Software is  MIssion Planner.

        • Thanks, it's making more sense now.

          When I first got started I had to change some parameters in ArduCopter(Arduino) and load them. I used the APM_Config.h tab for these settings. There are a lot of other tabs. Since loading ArduCopter on my control board I have made a lot of configuration changes through Mission Planner. How do I make changes in ArduCopter yet keep the MP setup I have worked out? I know this may require a long answer - if so, where can I go for clear instructions on how to use both the Arducopter code and the GCS Mission Planner code? Or is it even possible to use both sets? Will Arducopter somehow read (or can I upload from my control board) the current setup I have, then I can work with the code from there and re-write it to my CB?

            • Thanks, I've spent a lot of time on that site. My quad flies because of what I learned there. What I am not finding - or I'm finding it without knowing I found it - are instructions for making changes to the code that is already installed on my control board, while retaining the parameters that I have spent so much time adjusting via Mission Planner. I know Mission Planner just updates the CB code via the limited interface provided, but can't get to all the details. Can you direct me to the precise set of instructions? I just spent almost an hour looking and I can't find what appears to be what I'm looking for. It's like studying for a medical degree just to learn to remove a splinter.

              Again, I specifically wish to

              1. View the current code on my CB

              2. Edit that code without resetting everything back to default

              3. Upload the tweaked, but otherwise intact code back onto the CB

              I do highly appreciate the help.

              • I think I know what's happening: I can get to lots of parameters, but not all of them are available when using a knockoff CB loaded with Megapirate. This is my very first build ever of a quad and I didn't want to throw too much cash into it so I went generic. It was even against some recommendations that a first timer shouldn't mess around with Arducopter & Mission planner, but I wasn't going to start at beginner only to wish within a few days that I had gone for a more advanced setup. I made the right choices and got lucky with a quad that actually flies really well. I'll soon be ready to move to more sophisticated equipment and programming capabilities. This is such a cool facet of RC modeling & FPV.

                I hope someday I'll be able to help others with questions like I needed to ask on this thread. It is such a mystery starting out - and I'm still in that stage.
