Just a few words for now: I tried to imagine an even smaller Cri-Cri, in biplane form (Mitja would say... topspeedish-small at just 9 ft. 6 in. long), but also less complex, expensive and time-consuming to build. ...Woud it fly though, despite its span of 16 ft.? And how good? - This would be the major point of debate, being a real theoretical nightmare at a first glance (prone position of the pilot, sesquiplane, inverted V-tail... or sort of, electric and/or IC-propulsion etc. etc.) P.S: The pilot in the scale-image is... sort of me also, being 30 years younger and - more important - 30 lbs lighter :gig: than the actual Me.
