I decided to do a RockSim 9 sim on the Lucky 13. After all, the FLICS body panels are just flat fins. I just attached these 'fins' to a pod and moved it away from the body so that the 'V' is tangential to the body tube. At first glance, everything was copacetic. 592' on an A3-4 with an optimal delay of 4.7 and 600' on an A10-3 with an optimal delay of 4.3. But, I noticed a hiccup. The margin with an A3 is 0.5 but with an A10 is 1.2. Say what? I found RockSim thinks the A10-3 weighs ~1.8oz, vs. the actual weight of 3oz. Maybe someone entered the weight after burn out or only the propellant weight? Anyway, it looks like a margin of 0.5 would be acceptable IF I was confident of the accuracy of all my measurements. Methinks I'll see if I can find a way to attach a little weight to the wire loop in the base of the cone.
