Strake fairing kink

The plans have us build the strake skins with the outboard edge ending at the OD (outboard diagonal) rib. Notice how this leaves a wedge gap between the strake's outboard end - and the wing's inboard edge. This is done intentionally so that the builder can bond a piece of foam here and smoothly blend the strake with the wing.

When I finished installing the top foam skins onto my strakes, I noticed that if I held a straight edge parallel with the wing's leading edge, it would require the fairing block to have a drastic ramp or "kink" in order to mate with the strake... WHAT?! WHY?! Did I do something wrong?! Did I measure something incorrectly?!

I went back and triple checked all my measurements (waterlines, angles, wing incidence, etc), all checked out! So what was going on here?!

I then decided to pull up my CAD model and see if this "kink" in the fairing block was present in the original design. So I took a slice plane to the airplane...

...and positioned the slice plane to be parallel with the leading edge of the wing... here is a top view..

With the slice plane parallel with the leading edge of the wing... I could now zoom in and see if the fairing block had a smooth transition or not...

Zooming in...

Zooming in some more... it is very clear that the fairing block does NOT spline naturally with the wing's leading edge!

Notice the "kink" between the wing's leading edge and the fairing block... the OD (outboard diagonal) rib's top contour sits at a much higher waterline than the wing's inboard edge! In order to blend the wing with the outboard diagonal, the fairing block needs to "ramp up" to it!

Seeing this in the CAD model really helped put my mind at ease! I can now stop questioning if there was something wrong with the way I built the strakes and move on! What an emotional roller-coaster!
