Getting ready to trim the turtledeck for the flapperon cutout slot. I have seen two different styles of cutouts. The "curved slot" and the "straight slot". Is there a preference to one or the other or is one easier to re-install over the flapperon tube? Also, is there a blueprint of the cutout? I went through my stash of full size blueprints and couldn't find one for the flapperon slot. Thanks.
