This was the worst fight, had engine blow by. didn't go very high and melted the chute and cord. landed on its side and broke a fin loose but can be fixed easy.

Note:       When putting the engine together I put the delay grain in backwards and had a gap between the grain and closure. When I loaded the powder it fell through the hole and into the cavity. I pulled the delay out and put it in correctly, I tried to clean it off but still had powder on it , I didn’t think that would be a problem but thought wrong. It must have burned up or around the delay grain instantly. The flame blew up through that little hole in the closure and out the top to burn up everything inside.
