How to animate slots?

Hi!I don't know so I ask...how is it possible to make moveable slots (on front side of a wing)?They should act automatically, in dependance on speed (low) and angle of attack (high).I think it possible somewhy by using a special gauge? If so, where I should find example I can use?I'm using FSDS2...Regards, Rysiekhttp://strony.wp.pl/wp/rippippip/ http://rippippip.tripod.com/posting to http://www.simnetair.com/forumplvatsim/
