Even though the first flight was not a good one, the adapter seemed to have worked as advertised and I wanted to give it a second try. This time I loaded a 1/2A3-2.
The flight was much better but problems began at apogee. Instead of ejecting the streamer, the charge ejected the motor mount. The rocket came down ballistically, glanced off the GSE truck and hit the ground. The only damage was some minor crumpling of the BT.
