That's the kind of rockets we should have in Europe too.

good luck with the rocket tests, if after testing you feel there a bit on the large size, there is another option, a "hybrid motor" designed by the rocket master steve laduke.
speak to forum member fflach, hes built and tested these motors, and if i can remember correctly they can lift up to 650g!!!

Just found this. Remember that that guy had LOTS of safety distance in all directions -it didn't matter where the stick (plank!) came down.

More against the use of big rockets.... If as it says it takes 3.5kilos of whistle to lift a 12" shell it certainly doesn't take that much to lift a 12" ball shell maybe less than a kilo of BP! so you need more lift and a big stick to make a rocket.

agreed, large rockets are a bit on the silly side, they must be a purely technical exercise, although the grin factor must be immense!.
