<br>
Probably the biggest reason for top (or near top) hinging anything is<br>
weight savings when using very large ailerons on relatively thick wings<br>
as may be the case with AA 3D designs. <br>
<br>
If 45 degrees of travel is desired, and even if both the aileron and<br>
wing are beveled, a quite thick balsa edge is needed to do it<br>
conventionally. With top hinging the foam can be cut to the bevel and<br>
sheeted with 1/16, having only some 1/4" insets for the hinges. Saves a<br>
bunch of weight.<br>
<br>
As for the gap, on my Widebody 60 with top hinging and very wide bevel<br>
on the bottom (actual gaps sealed) there was no deleterious effect. I<br>
did tape (front edge only) some 1/64 ply "covers" over the bevel opening<br>
and saw no change in upright flight. Nearly crashed in inverted flight<br>
as the covers stood up like spoilers in the now lower pressure area<br>
(top). <br>
