Hi F3F diehards.

Look at this page to see how much is the drag created by the linkages of your plane :



http://www.mh-aerotools.de/airfoils/linkage.htm

The linkages account for a total 5 % of drag on your model. If you usually fly 40 sec., you could fly 38 sec. if you take away the lingages.

See how RDS works:

Also see my first homemade RDS :
