Looked real nice mate. Looks like you have your fuel nice and warm:). First couple were a bit scary. Do you have any personal inklings why the first couple turned so viciously? Love a good few rockets.
Also one other thing... These are nozzled rockets yes? I am really assuming here, but is your first rammer- the one that presses the clay. Is it divergent, creating a convergent-divergent nozzle?
Beautiful stuff mate.
Yes "Warm " Fuel, I have been working at taming them with my new BP made with my own Pine Coal, seems I need to bottom light to prevent cato with this BP.
As far as the turn, Only one really turned( spider stars), the others were pointed in different directions. I think my sticks were too thin, 1/4" x 1/4" x 2 feet. I should have put two on each rocket, I was testing the " no balance " theory, just need drag. the spiral on one would support the stick flexing too much. One stick worked on 3 of them well, Barley on the spiral , and not on the Spider one that turned to the right. These were cut from scarps in the wood shop and were of different woods.
These are nozzle less
