    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.

    @tridge
    Yes, ardupilot supports brushed motors. There are some commercial toy quads with brushed motors running ardupilot

    @marcsay
    Would there be DIY quads and hardware that can be assembled in the same way how the F450 frame is commonly used?

    @auturgy
    @marcsay yes: I’ve put ArduPilot on a couple of F405 tiny whoops before. On one (a brushed controller) needed to add a baro and compass. On the other, using a Revo-mini, I added a converter to drive the motors (found something on oshpark). There are also a couple of threads for 3” builds in the forum, but all brushless I think. Obviously the SkyViper RTF quads are around as well, which are ArduPilot out of the box if you get the right model.

    Hi. I'm using ArduPlane with QGC on Windows 10 PC (SITL). Does QGC upload terrain data to the vehicle the same way Mission Planner does? Because at the moment, it's not doing this..?
    Also, I wanted to ask if anyone's working on getting ArduPilot to work on that SeriouslyPro H7 board. That thing looks great

    Hello everyone , I would like to know that what is the current state of the ardupilot interface with simulink in sitl mode?I have seen some discussion over the internet in trying to implement that and now as ROS and gazebo interface has been added I believe that only modelling of the Ardupilot architecture would be left ? Am I right? What my aim is to model the ardupilot architecture in simulink and then playing with input commands and control things . Is it hard to do so ? what do you guys think?

    Is there a way to ban users from gitter? Sending the same message in all the channels is worth banning
    The docs only show how to connect it directly via the telemetry serial; I'm not smart enough to know if it is possible to connect it via I2C instead. If so, I'm trying to figure out if I should solder the Tx wire to SDA or SCL on I2C. Any thoughts?

    Thanks Patrick. I've reviewed that, but it does answer my question regarding an option for connection via I2C

    I have an answer from @auturgy. Thanks!

    @auturgy
    To put the answer here: no, it’s serial only, but Jimmy is (regrettably) using a mini-pix, so can reassign a pin to expose usart6
    (his problem was one Patrick knows well - more serial devices than serial ports).

    Hi all, who do I have to talk to regarding the firmware manifest.json file that should be used for firmware selection and download? I have some questions about redundancy of the firmware version.

    I am trying to iplement a new firmware install page for Apm planner and found some strange data in the file.

    @Arne-W Hi. What's strange?
    Arne Wischmann
    @Arne-W
    @peterbarker Hi - take a look at entry 1316 or 1317. The first thing is the version number that is encoded in the in the "mav-firmware-version-type" field too. It is the 3rd encoding of the version and in case of this entrys it seems to be wrong. The version-type field says "STABLE-3.6.8" and the version field 3.2.1. I would prefer to remove this encoding in the "mav-firmware-version-type" field as redundancy always is somehow error prone.
    Peter Barker
    @peterbarker
    @Arne-W OK, those aren't actually my changes - tacking on the version number to the stable isn't mine :-) I'll have a look tomorrow, 'though.

    Hi!
    I have a little problem with the Ardupilot connection with my computer
    is there anyone to help me?
    When I connect Ardupilot board to my computer, nothing happens, and my computer does not recognize any hardware.
    I use Windows10.
    what should I do? Am I missing some drivers?
    Arne Wischmann
    @Arne-W
    @peterbarker regarding the firmware manifest.json it looks like the version in the which is encoded in the "mav-firmware-version-type" field is the correct one (matches the file path) and the one in the "mav-firmware-version" is wrong (always 3.2.1). Moreover it is not possible to get those files which include the bootloader by reading the json data - you have to parse the filename to find the ones with BL and the ones without.

    have anyone already replicated the model of EasyStar II plane on JSBSim?

    @dmos62
    I'm looking for a budget-ish copter/plane/anything that's dev-friendly and has at least a minimum of modding potential. In other words Raspberry Pi of drones. Sky Viper Journey looks amazing, for example. Care to make recommendations?
    Or maybe there's a better place to ask?
    Olivier Brousse
    @OlivierJB
    Skyviper would be my recommendation. I don't know about the journey but I have a few of the originals (2450 GPS) an they are great. A few major advantages imho:
    • Very resistant to crashes. ;) Haven't been able to break one yet, and several took some serious beatings.
    • Full Ardupilot hackabity/programming, both flight controller and companion computer.
    • Full autonomy at low cost.
    • Can be used either with phone app or via your favorite GCS.
    Olivier Brousse
    @OlivierJB
    Next choice up would be a small quad, say 3" or 5", with full fledged Linux flight controller or non Linux FC + Pi or equivalent companion computer with camera. More possibilities given more computing power, but also definitely more expensive.
    dmos62
    @dmos62
    @OlivierJB yeah, journey seems to be a branding of their GPS drones. Are there kits or RTF for the linux flight controller quads you mentioned?
    marcsay
    @marcsay
    Would this be correct that if I use the Skyviper board, I can place it on a different frame and have it function with a DC motor setup? If I would use a Pixracer, I would still need a brushed motor controller connected between the Pixracer and the DC motor?
    Olivier Brousse
    @OlivierJB
    @dmos62 Not aware of any, there were/are some like Intel or Qualcomm Flight Pro with the snapdragon but support is discontinued, also has some proprietary code I think. But maybe someone will chime in that knows one I am not aware of. There's also Solo of course but discontinued + separate FC and companion computer.
    @marcsay Yes you can extract the board and use on different frame. You'd need additional brushed motor controllers if the motors were bigger otherwise if similar it's on the board already iirc. See also https://discuss.ardupilot.org/t/using-the-skyviper-sonix-board-with-any-pixhawk/23932

    hello guys, what is the best beginners plane to control either RC or with arduplane, with no experience in RC planes?
    jilliancfls
    @jilliancfls

    hi there!
    Im trying to deploy 5 vehicles (2 quads and 3 planes). They need to all transmit video, telemetry and rc quite far (60km) and all at the same time (all 5 vehicles). We have access radio towers 50m in elevation we are allowed to use to for the antennas and transmitters and receivers but im having a hard time wrapping my head around a few things.
    • If I put a bunch of high gain antennas to cover near 360º and simply alter the frequency of the receiver and transmitter, will that work given we will need to take these to their end of RF capabilities? (and their frequencies will be too close)
    • If I switch to a digital link, does anyone have any suggestions. I'm not too cost conscious. I don’t want 5 sets of 20k silvus radios but 2-5k for each system (I presume I will need 5) is ok.

    - It's just that doing the math, I can't get this to work on a fully digital links (i.e. microhard) unless i add such high gain antennas i need to start tracking them which i need to avoid. I want a healthy link budget so im trying to keep the frequency a low as practical but I cant use 900mhz, it would need to be 868 so a lot of the stuff ive seen isnt available in 868. I thought of ubiquity units but the 900mhz side back an issue.

    I am trying to manage how I can get 60km coverage (for telemetry, video and rc control) and not have all the vehicles not let the other have any RF space.
    Any thoughts (LTE is also out)? (edited)

    @krady21
    I'm interested in solving this issue (ArduPilot/ardupilot#13194). Is it still open?
    Pierre Kancir
    @khancyr
    yes
    Jaime Machuca
    @jmachuca77
    @krady21 That already exists or existed in the code check it first it was activated with a switch or throttle stick I believe
    Jaime Machuca
    @jmachuca77
    hmm... just double checked and I can't find the changes to enable it automatically with the crash check... guess they never made it to master.

    @southsideboats
    Is it possible to use GPS hold without altitude hold? I'm trying to figure a way to keep a tether from having a bunch of slack in it. I was thinking instead of holding altitude the UAV could just always be barely above hover throttle.
