I'd been on the fence about adding this type of plane to my arsenal, until getting the opportunity to take my good friend Gregg Boltons DSII for a spin. The plane was so stable and easy to fly, diving into the backside, axial rolls, inverted, it just did whatever I wanted with precision and ease. It was hard to believe this was a 90oz foamie, kind of a cross between a Cadillac and Ferrari Another plus is nice having the owner and developer of the Gulp series of planes as your neighbor, so naturally I decided to pay Steve a visit to talk shop about this build and get started. I wanted to shoot for 85-90oz dry with the ability to "load her up" on the really big days

Somewhat typical (yeah right) foam plank affair, with some serious mods:
Joined wing halves, double full length carbon spars, 2' carbon ballast tube, square carbon drag spar, potted HS-5245's, fixed 3" of elevon at tips, added spars in fuse at (LE & TE of wing) and put all electronics in the wing.
