royster Posted October 4, 2020 Share Posted October 4, 2020 After dozens of tests this is the first complete rocket i made. Its not competition material but it is the fruit of obsession. 4oz nozzleless on universal tooling with 2.5 inch ball shell.Cut willow stars with bp coated rice hulls and about 3g of slow flash. I dont know if its the proper amount of boost. I do know the stars were all different sizes and unfortunately i made them burn faster then what the composition called for, they burnt off right as it was getting interesting. Im definitely buying some star plates and will make them slower next time. I also found that i like the shorter delay better on the 2nd rocket. What do you think? Filmed with wide angle because sometimes i can't catch the suckers on the screen. I hope somebody enjoys 😁 Movie 3.mp4 1 Link to comment Share on other sites More sharing options...

justvisiting Posted October 4, 2020 Share Posted October 4, 2020 That was an excellent rocket(s)! If anything, maybe too good on the thrust, so the header was quite far away. You've got enough power to add a little (5-7%) coarse charcoal for a nice tail, and still have enough height on the burst. The propellant sure was zippy. How did you make it?

dlking59 Posted October 5, 2020 Share Posted October 5, 2020 I thought they looked nice. By slow flash do you mind telling what you are using. Link to comment Share on other sites More sharing options...

How did you make it? thanks, i think i do what everyone else is doing to get hot fuel, 75/15/10 thoroughly milled. I use weeping willow for charcoal because i have access to it, only thing i might do different is i finely granulate the fuel with denatured alcohol, no water at all, its seems fast when dry, packs nice and dries in about 2 hours.

rogeryermaw Posted October 24, 2020 Share Posted October 24, 2020 those were quite nice! i don't think i'd slow the stars at all but maybe next time, for an interesting twist, lighten the break slightly and add a touch of ferro-titanium for some long hanging, droopy sparks. good hot fuel there. even with a load that thing jumped right off the pad.
