I seem to be able to make them go with a slow take off ok but if i try to use a faster powder and a shorter core they still explode, so sticking with the sugar mix or a comp that burns at that rate (i have a charcoal mix too) can anyone sugest what migt be happening or give me some other dimensions to try?
Ihave been working to the spec on this link to which i have the missing jpegs for the dimensions http://huizen.dds.nl..._rocket_EN.html
many thanks
