I understand that the purpose of winglets is to decrease the wingtip vortexes to increase performance in climbs and cruising by redirecting the air over the wing. However on some old cessnas the winglets curve downwards. What is the reason for this?

$\begingroup$ @Pondlife The Cardinal II has wingtips that curve downwards, its difficult to get a good picture of it though. $\endgroup$– Ron BeyerCommented Mar 25, 2016 at 19:18
