The final flight occurred soon after sunset: the Big Blinka made its first flight on a C6-5. The LEDs worked great. For some reason, though, the Kevlar shock cord broke or burned through between the lower section and the parachute. The lower section landed close to the upper, though, and I was able to find it in the dark, where by “find” I mean “step on”. I couldn’t see in the dark what had gone wrong and I haven’t looked at it again since. But aside from the shock cord problem it seems to have been a successful flight.
