Paper claim: The physical aerodynamic design targets a safe static margin (SM) between 1.5 and 2.0 calibers.
Recomputed result: Barrowman computation using motor Estes C6-5, launch mass 1.209 kg, confirms SM ∈ [1.55, 1.57] cal. The sampled model outputs lie in the stated window. This does not establish dynamic stability, physical validity, or flight readiness.
