Flugg: it's closed by a wall.

Dick: It does have a large, 2 place slab sided canopy with quite a blunt windscreen which runs from the mid point of the wing to about 4 inches from the tail. Never considered the canopy. Will check this come spring. Would the extended gear counteract the effect of the canopy? If you go to google Curtiss helldiver page 1 and look at the title "1-1" you can see what my plane looks like. Should convince that the tail is large enough? There was a monoplane and a bipe called helldiver; mine is the bipe.
