No problem at all. KNSU doesn't have to be heavier, but there are trade-offs. KNSU has higher density and lower ISP than APCP, so you can shoot for equivalent performance with a size/weight trade-off, or equivalent motor size or weight with a performance trade-off. Either way there is a compromise. APCP is the dominant propellant for a reason Are there any retailers within driving distance that regularly stock AeroTech? If you can sweet-talk them into getting you RC reloads with their next order you might avoid the HAZMAT. |
