Great little rocket. Give it a high-visibility paint scheme (the one on the packaging works well for me) and load it up with the 1/4A to start with. No matter how high you think it’ll go on that little motor, it’ll go higher. Adapting down to the 6mm micro-sized motors works too.
It might be hard to see on the way down or once it lands, but if you can get everyone to be quiet, you might be able to hear it hit the ground.
If you’re completely crazy like I am, it even works as a two-stager.
