Don't fret Ken,
There's no reason a 3.4m wing should be as strong as a 4m wing.You can be confident in the strength of the Arriba' wing.
The low cost is a simple reflection of the higher costs to produce a larger sailplane.
The Arriba wing planform prolly has more in common with the 3.6m DG-600 wing.In looking over the Arriba picts Jared posted,it looks like flaps can be added if you should want more variety,increased roll rate,highly effective TE reflex/camber adjustment and even crow (not really neede with spoilers though).
Show us a build thread eh?
