    • RE: Required antenna

      Hello @local-ad those are U.FL (UMCC), IPEX MHF1 connectors. Those can be purchased from us here

      Any LTE antennas with a U.FL / MHF1 terminal will work.

    • RE: replacement body parts for RB5

      @MaxG we are currently low on stock of the replacement parts, but they can be found here on our web store. Please check back in the next week or two and those will be in stock.

      Replacement landing skids can be special ordered. Do you need the entire skid assembly or just the landing skid itself (black part)? Please send a picture to contact@modalai.com and we can get you the parts that you need!

    • S.Bus Receiver Compatibility and ESC Firmware

      Can’t get the connection working to the FrSky Receiver we installed, no inputs seem to be visible in QGroundControl – Is the installed PX4 firmware compatible with the FrSky S.BUS receiver?

      Are we missing any settings?

      The motors aren’t working, it seems the ESC Firmware is missing (fast flashing blue light) – where to get it?

    • Use onboard vision system for stabilization and disable the GPS/compass?

      If you go into QGC select [vehicle setup]-->[parameters], do a search for EKF2_AID_MASK. It should be 280, which means ignore GPS and only vision is used for positioning (can literally disconnect gps to confirm if you like). This should have been shipped as default since seeker is an indoor mode drone. Turning off the compass is just a couple more parameter settings, but let's go one step at a time.

      Beware of your failsafe settings and that vision control requires good lighting conditions. This is a very critical point for [any] VSLAM to work. If there's a vision fault (e.g. bad lighting) the drone will typically drift away from position hold such that you need to put it in manual mode or alt-hold mode to regain proper control. The position control camera is the 45degree down facing camera--hence good ground lighting is desired.

      If EKF2_AID_MASK is not 280, cancel out of that and click on parameters again, select [tools] and [load from file] using the indoor parameter file you can get here. If you check the aid-mask parameter again, it'll be 280.

    • Can you use the Seeker VOXL Cam portion and put on another frame?

      Yup, you can take the Seeker VOXL Cam portion and put on another frame.

      If you do, ensure that it's in the same orientation with the VIO or downward camera with a clear view.

      For PID tuning, this PX4 guide is very helpful: https://docs.px4.io/master/en/config_mc/pid_tuning_guide_multicopter.html

      Here's a link to PX4 helper parameter files that we use to switch between indoor and outdoor modes: https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/tree/master/helpers/seeker

    • Blue LED does not flash once PX4 and VOXL boot up

      When booting up the VOXL Flight it is expected to have the normal green solid LED and flashing blue LED.

      The issue is that the blue LED does not flash once PX4 and VOXL boot up.

    • RE: m500 using extended RB5 landing gear

      Hi @yu-zhang we are not offering extended landing gear at this time. You can extend the tubing on the landing gear legs if you would like more height on the M500.
