I wish the video actually had him using it to hit a drone or something. As is, it only shows one actual launch, and it didn’t look all that impressive. His motors didn’t seem to have enough umph to let the missile stabilize properly.

That is what is needed more than anything, a way to take down drones.

Potassium nitrate and sugar. The first video is worth a look. He’s released another but I haven’t had a chance to check it yet.
