I appreciate the input and I understand what you are saying but that is not the case here. The stab is constructed correctly. It is built up from ribs, similar to a wing then sheeted. It may not appear to be in the pictures but it has the correct shape. Curved or airfoiled just as you describe. This is determined by the ribs supplied in the kit and matches the plans and instruction photos exactly. You can clearly see this by looking at the tip block which has been glued in place but not shaped yet. It is still flat and the rest of the stab is clearly shaped properly.

It is clear that the elevator LE is narrower than the stab TE. I want to know if this is intentional or if the stab LE's supplied were cut incorrectly. They were laser cut from 1/4" balsa sheet. The cutting was pretty bad; very burnt and not perpendicular to the sheet (irregularly angled edges).

Like I said, I can easily correct it with some 1/16 balsa but I want to make sure it is really a problem before I do that.
