"Underfed Connie": There is certainly not used many rulers at the designshop of De Havilland. it's extreme slick and as it shares the Plywood-construction with the Mossie i wonder if the strenght of the plywood lies in this un-edgy design :-/
Prop' size: Until now I've considered the treshold between two and three propellarblades to be about 700hp, but as it seems that the Fokker are on the limit it might be in the area of this 500hp instead :-/
Maybee the simplicity of the wooden fixed pitch double prop' did delay the decision of upgrading to three blades :-/
