Two Stage Rocket Setup

Bad cold, could not talk at all, sorry
This is for anyone curious about how I set up the 2 stage rockets. Please ask questions if anything is not clear - thanks!

Do you attach two sticks or just one to the second stage?

@pyrozmuro One stick is attached. I haven't yet tried adding a second shorter stick, but I got to thinking it might be a good idea for a smoother flight - I'll try that next time.

Well done! Is the booster made with a sandart Stinger tooling? If yes how much can it lift and how many increments will I need to press it(Increments and how much fuel is needed) . I think they were much faster to press than a standart 1lb engine and can lift some weight for... lets say... small salutes.

@pyrochemieNET Yeah Jack, standard stinger tooling. Not sure of the maximum lift capability, but the second stage weighs around 150-155 g (including the stick), if you add a small report on top now you are at the 200 g level - it easily handles that weight. About 40 g fuel was used in 1.5 teaspoon increments, and there are 6.5 total increments, more or less - I cut the tubes to 2.75 inch length.

Very nice, acually same way as i couple my two stage bp motors, the method you use, makes it actually a bit "unconventional" ignition of the upper stage, right? i mean, since the small bp charge burst into the core and not just "touch" the bottom section of the grain, good to see this works on whistlers
