# Test 2017-12 # 5 grain 75mm sorbitol motor with pyrodex pellet ignition in 4-inch Wildman rebuilt airframe at NCR North. Trimmed CTI 5-grain case (25.75" overall), Loki #42 nozzle, CTI aft closure ring, forward bulkhead from Terry's pile machined to have 0.5" inside snap ring plus 0.25" inside liner, with two o-rings, one pushing against liner. Liner 23.125" long with about 22.25" available for fuel load. Had to trim grains to fit. Four just required squaring up the ends and trimming excess casting tube away. Fifth one was cut in miter box with saw. O-rings made forward closure a *very* snug fit.

Neglected to re-weigh grains after trimming and before epoxying into the liner. * Grain , g gross, g net, 4.5" long * Grain , g gross, g net, 4.5" long * Grain , g gross, g net, 4.5" long * Grain , g gross, g net, 4.4375" long * Grain , g gross, g net, 4" long Total of g propellant, vs g simulated. ## Results ## Flight data logged as ? sn ?, flight ?.
