Does anyone have any tips on the aileron tips?
The skins come bent pretty tight, I followed the new pictorial assembly guidance.
When I got to trimming for the outboard tips, the dimensions in the drawing
(640-a-1) just didn't make sense. The rib 4 rivet line is 195mm inboard of the
untrimmed edge, the detail says add 15 mm to the rivet line and start the cut,
which should be no more than 135mm from out board edge. 135+15 is 150mm, not
195.
Anyway, cutting in 135mm would have you cutting into the hinge. So I made a conservative
add of 15mm from the end of the hinge, then drew straight lines to the
corner of the bottom trailing edgeand to a point 40mm back from the top bend.
that is someting on the order of 120mm cut back.
Started to try to fit the aileron tip cap on and it just isn't going to fit. Cutting
deeper would make the problem worse.
Did anyone have any trouble figuring out how to trim the tip, or did you trim it
to match the finished wing?
