Right. I don't think the high aspect ratio of Draco was the direct factor in his loss of control. But the extreme low aspect ratio of the V-173 is more roll stable in the high angle transition to vertical hover. The V-173 stalls at around 40° and Draco may have stalled at around 25° with the slats. I don't have the data on slat wing stall angles.That'll do it to any light aircraft..
Mike might have got away with that takeoff in a Helio Courier. The Helio has big spoiler knives in front of the ailerons and with full spoiler on the left wing it might have kept his left wing down.
