The aircraft looks stable in flight, although we only have the still picture, so it’s hard to say for sure. The gear collapse confirms your wisdom in constant testing and re-testing, and waiting for the proper parachute. Now is an opportunity to design a more durable gear system, perhaps one that is better suited to dry lake bed terrain and winds. Lots of aeronautical knowledge in your own experience and in those around you. We should be able to devise a lightweight, strong, versatile, and durable system.
