Hi, looks like very interesting project.

Did you mannage to complete the flight?

You should be able to arm pixhawk through the QGC or Mission planner. I know for sure that in QGC you can do it.

hello we are from a school and we are going to use a weather balloon and attach the Pixhawk to send data to our ground station via 2.4 video … As the balloon ascends, the pressure of its environment slope unblocked decreases, and the balloon begins to expand. This expansion continues until the material of the balloon is stretched to its breaking point, causing the balloon to burst. This typically occurs at stratospheric altitudes between 30 and 35 km.
