Tip
  • Didn’t crash

  • ~1.5ish comp laps with 4x 5000mAh batteries (old batteries)

  • Flew at 30m/s (108 km/hr ground speed)

  • RFD900 works

  • RTK got to fixed mode at 5mm accuracy

  • Set up quickly and followed checklists

  • Checked the pre-arm warning in the bay before leaving

Note
  • Speed was unpredictable. set at 18 m/s but flew at ground speed 30 m/s

  • RTK easily switches back to float

  • Noise in the video signal

  • Didn’t have a mission planner setup with coordinates for task 1

    • Meant we had to adjust it in the bay before and also during the flight test.

  • Lack of visual observers - most people heads down on the laptop. Someone on the flight line should be looking at the drone at all times

  • Very fast turns - acceleration at direction changes looked very high

Warning
  • LTE dropout

  • OSD dropout (same interference probably)

  • Batteries very uneven voltages, failsafed and had a mid-rough landing at the end of the 3rd flight.

    • probably cooked for good. these ones are bad now.

      • good thing we’re getting new batteries on monday

    • can use a couple of them for ground tower things, but shouldn’t fly them again

Card #1 Debrief

Flew 4 flights total.

Flight #1

Took off in typical configuration, experienced GS Lost Link after ~ 5 seconds. Continued mission until first waypoint, and then failsafed into RTL.

LTE was swapped for RFD900’s.

Flight #2

1.2km total flight

Action items

  • Reset the LTE module because current settings made it worse

  • made a board that switches RFD to LTE

    • takes PWM input

    • Do we have GPIO? -@aidan

      • if so we can just use this to switch transmission

    • Can we just measure RSSI?

      • LTE doesn’t report a RSSI.

      • need a LUA script to say ‘if disconnected' check after 20 sec and if still disconnected, switch over.

      • This should be ok for comp because control is still connected. ELRS.
