Anybody with experience want to talk about how/why this happened? Seems like part of the problem was the small opening on the right side of the plane. But I imagine its should be designed to not break so easily considering the use case. In addition, I’m surprised the canopy would open instead of staying locked. Good thing this pilot didn’t panic and was experienced enough to still safely land the plane.
You can probably do a “paper clip” test to help you confirm its the PSU and nothing else. Basically removing the PSU and connecting a paperclip to specific pins on the PSU to act like an “ON” button.
But based on the symptoms you’ve indicated, it does sound like a PSU problem. Nollij’s idea of buying another PSU that would allow you to return it sounds like another good solution/test.
