Tube fins I gather have a lot o' drag. So I was nay too concerned about usin' a B6 in t' confined space o' t' smaller SCRA launch area. Avast! Plus this ole warhorse is pretty rough on t' outside. Great flight with ejection just after apogee. Ya scallywag! T' POS stiff Quest chute did nay deploy but it tumble horizontally onto t' soft grass with no damage.
