    I was just wondering about something more general. As far as I know, there is no parameter for the position of the compass on the copter. Why is this not necessary?
    Akshath-Singhal
    @Akshath-Singhal
    @fabianfaul I believe the heading will be independent of the position of compass and depend only on its orientation. Can you provide a case where the said assumption is not valid if you believe otherwise?
    Fabian Faul
    @fabianfaul
    @Akshath-Singhal, not really. I'm just not sure what happens when it comes to pitching. The compass delivers 3-axis values and some will change more than others, depending on how far the compass is mounted from the flight controller. I think this is a question of how the actual heading is calculated.
    I was also wondering how exact the compass must point to the front of the copter, i.e. how exact the compass must be.

    Hi, I have a ublox m8n rtk module. What is the correct value of EK2_GPS_TYPE?

    I am flying drone autonomously and controlling drone using GUI(GCS) which send and receive commands from RPI attached to Pixhawk, i am using mavlink commands to control the drone, i found 1 major misbehavior which happens very rarely, once in around 100 takeoffs, my drone start to move in one direction itself just after takeoff, when my drone behave like this then it stop listening to any mavlink commands given either from GUI or running at the backend of RPI, it doesn't even listen to land command, it goes completely out of control and keep flying in one direction, it's quite dangerous, anyone know any reason for this misbehavior or can suggest something to control my drone when it start to misbehaving like that

    umm Hey guys, sorry but idk if its a right place to ask something... Im very new to open source and I needed a little help to get started and also I had a few questions to ask related to the Mission Planner.

    @thefallenangel666 There is a development gitter channel for Mission Planner. https://gitter.im/ArduPilot/MissionPlanner?utm_source=share-link&utm_medium=link&utm_campaign=share-link
    @peterbarker i raised

    Who would be the person to talk to about cost to sponsor a feature? I'm trying to get a number to put on a budget for the people up the chain.

    @TunaLobster ArduPilot doesn't do paid support or development. But individual developers and companies do, we even have a page for commercial support: http://ardupilot.org/ardupilot/docs/common-commercial-support.html

    @TunaLobster
    @OXINARF Thanks! I wasn't sure who to contact on that list that might be will to do it. The fuel flow driver is the closest to what I am looking for so I might try RFD.

    Hi, can bad PID tuning result in 250mm quad taking off normally and then flipping mid air in Stabilize mode (in 4-5 m/s wind?)
    In DataFlash, Roll follows DesRoll and Pitch follows DesPitch, so I don't think it is a motor issue

    Hello everyone, can I ask here about simulation problems?

    i'm trying to simulate rascal with JSBSim, when I launch it, the plane doesn't appear in the map
    anyone can help me?
    Francisco Ferreira
    @OXINARF
    @VinhA2018 better to post it on main chat: https://gitter.im/ArduPilot/ardupilot Also please say what exact commands you are running and in which environment (Linux, WSL, Cygwin, etc...)

    Hi all ... I have baitboat and a question is it possible for each point to be the end point ?? E.g. I have 10 points on the map and I could choose to make the boat go to point 7 and back to the house but without passing through other points ?? Thank you in advance for your answer...

    @edsellar
    Is it possible to set up a servo gimbal on a pixracer (ie something without aux channels?)
    Peter Barker
    @peterbarker
    @edsellar naming is a bit interesting; we generally refer to pins coming from the flight controller as aux chanels and from the iomcu as main outputs. Given the PixRacer doesn't have an IOMCU, all outputs are kinda aux channels. But to answer your question, yes, you can set up a servo gimbal on a PixRacer.
    edsellar
    @edsellar
    .
    Oops. Thanks @peterbarker I’m just used to reading the online docs which either talk about the old apm ports or the aux channels on the pixhawk so great to hear this is possible on a pixracer. I’m going to have to pick one up to try for a smaller build. Thanks 👍👍
    Peter Barker
    @peterbarker
    @edsellar We'd like to stamp out everything to do with the older APM hardware, so if you spot anything which isn't marked as old-news, please let us know.

    Is astyle(http://ardupilot.org/dev/docs/style-guide.html) still used? I was working on solving this issue(https://github.com/ArduPilot/ardupilot/issues/12819) and after using astyle on mode.cpp and takeoff.cpp i have found out that it changed parts of the file that i didn't edit myself.
    Francisco Ferreira
    @OXINARF
    @krady21 It's not perfect so we don't run it automatically. It's best to just do it manually to be honest

    Hello everyone! I was trying to setup SITL in my Ubuntu 18.04 environments and the git submodule command fails. What could be the possible reasons for this issue?
    N Krithick Santhosh
    @Krythz43
    Okay, I solved it and I had to use git config --global url."https://".insteadOf git:// to get it running behind my proxy sever. Can I send a PR regarding this updating the README.md file?

    What is the main difference between ardurover omin-x and omni-+, I have a rover with mecanum wheels and not sure which to use x or +
    Pierre Kancir
    @khancyr
    Like for copter, in + the front wheel is the center and the front and rear and the pixhawk are close to be on the same line
    Think in view from top with the controler in the middle and giving you the front.
    adalta87
    @adalta87
    so with four mecanum wheels located at each corner of a rectangle it should be set to omni-x correct? https://discuss.ardupilot.org/t/how-to-setup-this-type-of-rover/37523/5

    can I achieve multi UAV GCS telemetry link using RFD900? Anybody experienced this setup?
    I found that there is a param called NODEDESTINATION. Using this, RFD attached to GCS will broadcast(NODEDESTINATION=255) and UAVs will only target the RFD in GCS using its NODEID?

    Hello, I just wanted to know if there is a proper method to cite Mission Planner. The format that I am referencing the software is: Mission Planner, [Computer Software], ArduPilot Development Team: [missing the city, and country], 2012.

    Hi, this is Aditya. I am in my pre-final year studying Computer Science at BITS Pilani Goa, India. I got very interested in the project which was offered by ArduPilot in GSOC 2019 by the name "ROS integration with Copter and Rover for non-GPS navigation and object avoidance". How do I get started if I want to contribute? I have prior experience with ROS and I am currently working on autonomous navigation on a mars rover.

    @OlivierJB
    Hi @AdityaKapoor74 you can check out the Ardupilog/GSOC channel here on gitter, also go through some posts on discuss like https://discuss.ardupilot.org/tags/gsoc19. Best would probably be to get familiarized with the code, perhaps look at some open issues and practice on some PRs.
    The GSOC 2020 season hasn't started yet, when it does it will be announced on the discuss forum

    If Ardupilot is accepted again it will be announced around February 20, and the student application period will start on March 16

    Hi, is it possible to have an Ardupilot board connected to a micro quadcopter frame using only DC motors? We are wondering if it is possible to have a micro size toy drone having Ardupilot capabilites.
    Andrew Tridgell
    @tridge
    Yes, ardupilot supports brushed motors. There are some commercial toy quads with brushed motors running ardupilot
    marcsay
    @marcsay
    Would there be DIY quads and hardware that can be assembled in the same way how the F450 frame is commonly used?
