I'm planning out motors for a launch at MWP in Nov. I'm thinking about a 6-grain longburn. Has anyone ever flown this on a CTI K260-CL? Seems like it shouldn't tax the airframe too much.
Flight calculations:
Motor: CTI 54mm 6-grain K260 CL
Stability calibers: 1.39
Thrust-to-weight: 260 N / 4.17 kg = 6.4:1
Velocity off rail (6): 17.2 m/s (38.5 mph)
Velocity off rail (8): 20.5 m/s (45.9 mph)
Max acceleration: 81.6 m/s2
Max velocity: 263 m/s (588 mph = mach 0.78)
Apogee: 2,648 m (8,687 ft)
Has anyone pushed this airframe past mach? I'm a bit nervous about having it sit in the transonic region, so I'm staying under mach 0.8.
