I flew the Luna bug three times on Friday at the edge of a newly mowed soccer field. First flight was MicroMaxx in an adapter, went much faster and higher than I thought it would, ejected going up, and, streamlined in but not too fast, landing pad drag I guess, and didn’t bury itself. It landed three feet from me right next to the bleachers. Next I tried a 10 year old 1/4A3-3, I angled the rod a little more and it went higher,but the thick tracking smoke made it easy to follow, and was easy to see the rocket at ejection (clear skies sun low in the sky). A moment after ejection I heard a ‘pingggg’ as the ejected motor hit the bleachers two feet from me, so I recovered the motor and rocket. Third flight was another 1/4A from the same pack. After liftoff the Luna Bug turned sideways at 10 feet, burned out and tumbled it’s way to a low apogee, then started tumbling toward the ground when it ejected at 20 feet, so the rocket and motor were just 25 feet from the launcher. It looked like the motor nozzle, which was the white fine poopy clay, had ejected part of the throat, effectively making the nozzle larger and offset to one side, vectoring the thrust. Overall, this is a nice little rocket.

MM flight. Keep an eye on the upper left after the pop:
