Posts: 757 japan | Darryl, the pics show some sexy looking kick up rudders on some/earlier? f14's as well as the t-foil rudders.
notice that the t-foil rudders are not kick up but have their own special up/down carbon sleeves
is that because the upward forces they generate don't work well with the typical kickup system, or are you just trying to keep the t-foils at the lowest drag angle all the time. i can imagine that if the rudders were put up or down the usual way the t-foils would act as huge brakes....

I think you answered you own question, plus I think you would break something while "kicking" the rudders up - unless you are not moving. <img src="http://www.catsailor.com/forums/images/graemlins/smirk.gif" alt="" />
