I've read a bit on slotted flap design here, and gone through Theory of Wing Sections and the rule such as it is seems to be to make it look about right. What do yo reckon? Looks ok?

I've gone for just over .01c gap on a 25% flap chord. Airfoil is Wortmann FX 79 K 144/17.

Regarding actuating it... I can't quite get my head around whether I need two control linkages toward each end or if I can do it from one central one. What's the usual for a fairly long (2.4m / 8foot) slotted flap?
