Home made 5 sided "saucer" with KnSB-2 bates grains o' propellant in a 38/360 case. Out o' ignighters so I had t' use a fuse. Aye aye! Would have gotten up t' speed quicker with an e-match and head end ignition and some iron oxcide for catalist in t' propellant. Ya scallywag! Kinda wobbled at t' end?
