One last thing.... how many of you guys 'seal' the hinge-lines on your planes? As in use covering to seal one side of the control surface? My father is an old-time flyer and kept mentioning that it would greatly improve my airplanes performance. However, when I did this to my SS nothing really changed; maybe a click or two adjustment to the sub-trim but that was it. So when I'm building this should plane, do you guys recommend that I do this to the Ultimate?

Thanks for your thoughts,

Mark
