Good afternoon,
I was wondering what considerations might influence the location of the horizontal foil on the rudder blade.
There seem to be several cherubs running the foil as an inverted T but i dont understand the pro's and con's for moving it up or down the rudder blade. 14s tend to have them mounted closer to the surface, but i dont know the reasoning.
A separate conversation is around where it is mounted in the horizontal axis on the rudder. leading edge, infront of the rudder, mid rudder or trailing edge. I can see the further forward it is the great the reduction in moment around the rudder stock pivot for changing the angle of attack.
Thanks,
Ed
