Greg,

working on it. There are still some issues.

One thing I can't recall from the build and can't tell from the tracings is whether the TE of the ribs is constant. The LE appears not to be and by looking at my wing it isn't either - it tapers to a thinner tip LE.

The TE however, I don't recall having to sand down the 3/8" thick aileron stock to a thinner aileron. In fact, the wing tip is a piece of 3/8" balsa which, if I recall my build correctly, means that the sheeted tip TE should also be 3/8" thick. The problem with that though is, if its the case, how does one end up with airfoil contour at the root! It would be way too thin!

I recall maybe sanding my ailerons to airfoil slightly and the wing TE is a piece of 1/4" x 1/2" to allow the sheeting to be butted up against the TE which is then sanded down. The root TE thickness at the hinge line ought to be 3/8" to match up with the aileron.

In short, it strikes me as though the rib TE thickness ought to be uniform at a tad over 0.25" so that when one adds the 1/16" sheeting the thickness is just over 3/8" in order for it to be sanded down to 3/8" thickness at the hinge line.

Make sense to you?

David.
