Bean. More thread drift. Regarding tabs, I can't recall for sure (it was 32 years ago I left the fleet). Pleasant to fly, yes, except when flap was deployed. Aileron response then was rather sluggish. Perhaps the reason Fokker put the "foklkets" on the F-50 wingtips, presumably to limit spanwise flow. Built like a tank, and could take anything the weather could throw at it.
