Elevon Servo hatch modifications
The following photos show the modifications that I made to allow for a standard servo and use the stock flat servo hatch cover; I drew up new formers in AutoCAD and made some trial fittings.
I decided to cut out the skins with the hatch openings and flip them 180 degrees in the wing panel. The new position allowed for a standard servo to sit within the confines of the wing cord. I used a razor saw to cut the panels out, after re-gluing the panels a fine panel line remained which I will paint in with a darker color to accent the line.
