Definitely true about A LOT of drag on PSS biplanes. Probably a lot less drag on the Rutan model than on my Beech Staggerwing.

Sounds like a great project.

Ive heard of biplane PSS and it always went wrong because the airfoils were too draggy. The extra wing provides extra lift, but also lots of extra drag ..

Go for it! Id like to see a plane that nice flying as a sloper.
