Model weighed in (fully loaded) at 11.25 ounces. Well, blow me down! Quite heavy for a scale model o' that size.  Liftoff was very good, t' D12 gave it a nice acceleration, matey, more than I expected.  However, at burnout thar be a slight "wiggling" but t' Atlas - V straightened up and continued up for more altitude (probably due t' t' extra mass given by t' weight) where t' ejection charge went off right at t' apex (apogee), arrr, allowin' both parachutes t' deploy nicely.
