Flight Test Post Mortem
Tip |

Didn’t crash! Collect sufficient footage for proof of flight Range testing on 1.3GHz was successful with stable video @ 150m altitude Smart about taking risks, made sure to investigate any problems, were cautious with any issues Staged testing approach was effective Batteries did not sag, at the end we were close to 7% capacity Used custom WARG hardware (michael’s buck converters) for the ground station! Effectively communicated with other people at WRESTRC Verified ground video station Got ample footage for CV training with landing pads

Radio protocol usage can still be improved Communication before taking off could be better Priority of flight test: Cornflakes shouldn’t necessarily have to wait for other drones (e.g. the DJI) to get ready Practice with DJI drone usage Communication after landing on next steps Forgot nuts for wings, had to drive back (add to checklist) Radio chatter during Houston flights was a slight problem for PIC Almost forgot Houston props (again) Make sure checklists get published on confluence Servo trims did not save (potentially done by clicking extending trims) All of these items were rectified, but could have likely been rectified beforehand 1.3GHz vtx wire was loose on Houston Ground lead on the video relay was loose at the bay Props were loose on Cornflakes were lose before first flight RFD Harness was loose
Fish-eye perspective on Houston downwards facing camera is difficult to perceive distance 4:3 and 16:9 causes image to be stretched on monitors Batteries were almost not charged before we left due to being unbalanced Car battery charger is roughly useless - faster to charge by driving Communicate at least one other person if leaving the group, even if you’re wanting ‘to go’ High vibration on Cornflakes as reported by the flight controller Avionics platform is all on one single platform that’s not really stiff Telemetry wiring was not ready for the flight test Back third of the cabin was destroyed on the flight line, was successful but was necessary Diagnosed an issue last flight test that was only partially addressed Did not test the Vector-Nav. Did not test waypoint following Did not test autoland

Warning |
---|
No discussion on action items if crashes, Did not achieve 20 m/s transition speed Reached 15 m/s with tailwind (12 m/as TAS) Potentially want to fly on 17 inch Add airspeed sensor to aircraft
Signal wire on motor 5 / pusher motor was poor and disconnected during/before flight and was only found out in the sky
