Santa ... Ya scallywag! be afraid, me bucko, be VERY afraid! At this year's MDRA Christmas Tree launch, we kicked it up a notch by drag racin' 'em. Note that t' rightmost tree in t' big race had its motor mounted on t' "wrong end", t' optimize t' tree's drag profile (make t' branches bend back towards t' trunk instead o' further out in t' slipstream). Well, blow me down! Judge for yourself how effective this strategy was. I wonder if t' trees would all corkscrew counterclockwise if we launched 'em in t' Southern Hemisphere...
